Description:
FIELD OF INVENTION 
     This invention belongs to the field of the systems for drought resistance in plants, in particular, of those systems related to the irrigation of electrons and protons at the plants roots for drought resistance, more particularly, relates to systems of two components: a liquid fertilizer providing protons and ions and an electric circuit providing electrons to the plants roots for drought resistance, naturally supplying the components of the water photolysis without the need of any genetic handling in plants. 
     DESCRIPTION OF PRIOR ART 
     World population increases at a great speed. One of the problems arising from this scene is how the increasing food demand being generated therefrom, is being met. 
     In order for the food demand to be met, an increase in the performance of the cultures will be necessary. Apart from the new technologies that are being developed around the world to achieve this object, it is essential to have an appropriate rain regime. A drought at the time of flowering of a cereal as well as the high temperatures and solar radiation drastically reduce its performance, causing severe economical damages and food shortage. A global drought could generate the greatest worldwide crisis over the time such as famines, wars, diseases, great migrations at global level. 
     This detailed analysis made by Aiguo Dai from the National Center for Atmospheric Research (NCAR) leads to the concerning conclusion that the increasing temperatures associated to the climate change will probably create, each time more firmly, the adequate conditions for drought, throughout the world, in the next 30 years. Besides, everything indicates that by the end of this century, in some regions the drought will reach a magnitude that has never been seen before or perhaps only in certain occasions: 
     By using a group of 22 climate templates by computer and an exhaustive index of drought conditions as well as an analysis of previously published studies, the new investigation indicates that most of the Occidental Hemisphere, together with wide zones of Eurasia, Africa and Australia, may be under the threat of extreme drought in this century. In contrast, certain regions of high latitudes, from Alaska to Scandinavia, are prone to become wet. 
     Dai advises that the results of this analysis are based on the best present projections of greenhouse gas emissions, but what is going to happen in the coming decades will depend on a lot of factors, including the future real greenhouse gas emissions as well as the behavior of the natural cycles of the climate as the meteorological phenomenon named “El Niño”. 
     Dai&#39;s study indicates that most of the two thirds of the occidental region of the United States will be significantly drier within 20 or 30 years. A large part of that nation may face an increasing risk of extreme drought during this century. 
     Among the other countries and continents that could face an increasing risk of significant drought, the following may be mentioned:
         A large part of Latin America, including large areas of Mexico and Brazil.   Regions that adjoin the Mediterranean Sea, which may become specially dry.   A large area of the Southwest Asia.   Most part of Africa and Australia, with particularly dry conditions in certain regions of Africa.   Southeast Asia, including areas of China and adjacent countries.       

     The study has also disclosed that it is expected that during this century the risk of drought will decrease in a large part of the north of Europe, Russia, Canada and Alaska as well as in some areas in the south hemisphere. However, the planetary average will be of most serious droughts. 
     It has been estimated that the factors of environmental stress cause a reduction in the performance of the culture of up to 70% in comparison with the performance in favorable conditions (Boyer, Science 218, 443-448, 1982). Accordingly, the stability of the culture as regards the changes in the environmental factors is one of the most valued features for the reproduction. However, the traditional reproduction is restricted by the complexity of the features of stress tolerance, the low genetic variance of the performance components and lack of effective selection techniques. Accordingly, it may be useful to follow specific genes codifying components of stress tolerance in the reproduction by markers assisted selection as well as by genetically modified plants to be more tolerant to the stress. 
     Among the complexities of the reaction to the environmental stress in the culture plants, the use of the simple template for  Arabidopsis  offers an opportunity for the precise genetic analysis of the stress reaction pathways common to most plants. The importance of the template for  Arabidopsis  is evident in the recent examples of enhancement of tolerance to drought, salt and freezing (Jaglo-Ottosen et al., Science 280, 104-106, 1998; Kasuga et al., Nat. Biotechnol. 17, 287-291, 1999) by using genes identified in  Arabidopsis . These genes are factors of transcription of the family ERF/AP2 that regulates the expression of several genes downstream which confer resistance to stress in different heterologous plants. 
     One of the most serious environmental stresses that have to be borne by the plants worldwide is the stress caused by drought or the stress caused by dehydration. Four tenths of the world areas intended for agriculture is located in waterless and semi-waterless regions. Furthermore, also the plants cultivated in regions with relatively high rains may suffer drought episodes during the growing season. Many regions intended for agriculture, especially in countries under development, systematically have short rains and depend on the irrigation to keep the performances. Water is scarce in many regions and its value will undoubtedly increase with the global warming, resulting in even a greater need of culture plants tolerant to the drought, that keep the performance levels, or even better performances, and the performance quality in conditions of little water availability. 
     Even though the reproduction, for example, the one assisted by markers, for drought tolerance is possible and is being applied to a variety of culture species, mainly in cereals such as corn, rainfed rice, wheat, sorghum, pearl millet, but also in other species such as  caupi, guandu  and  alubia Phaseolus , it is extremely difficult and tedious as the tolerance or resistance to drought is a complex feature determined by the interaction of many loci and gene-environment interactions. Accordingly, there is a need to find unique, dominant genes that confer or enhance the drought tolerance and that may be easily transferred to varieties of cultures and lines of high performance reproduction. A large part of water is lost through the leaves by perspiration, and many transgenic approaches have focused on modifying the loss of water by means of a change of leaves. 
     For example, the document WO2000073475A1 describes the expression of a malic enzyme C4 NADP+ of the corn in epidermic cells and occlusive cells of tobacco which, according to the disclosure, increases the efficiency of the use of water in the plant modulating the stomatal aperture. Other approaches involve, for example, the expression of osmoprotectants such as sugars, such as the biosynthetic enzymes of trehalose, in plants to increase the tolerance to the water stress; see document WO1999046370A2. Other approaches have been focused on changing the architecture of the plants roots. 
     Up to date, another promising approach to enhance drought tolerance is the over-expression of genes CBF/DREB (DREB refers to binding to an element of response to dehydration; DRE binding) codifying several factors of transcription AP2/ERF (factor of response to ethylene); see document WO1998009521A1. The over-expression of proteins CBF/DREB1 on  Arabidopsis  resulted in an increase in tolerance to freezing, also referred to as tolerance to dehydration induced by freezing (Jaglo-Ottosen et al., Science 280, 104-106, 1998; Liu et al., Plant Cell 10, 1391-1406, 1998; Kasuga et al., Nat. Biotechnol. 17, 287-291, 1999; Gilmour et al. Plant Physiol. 124, 1854-1865, 2000) and improved the tolerance of the recombinant plants to the dehydration caused by hydric deficit or exhibition to a high salinity (Liu et al., 1998, supra; Kasuga et al., 1999, supra). Another factor of transcription CBF, CBF4 has been described as a regulator of the adaptation to drought on  Arabidopsis  (Haake et al. 2002, Plant Physiology 130, 639-648). 
     The document WO2004031349A2 describes a factor of transcription referred to as G1753. This reference also describes plants of transgenic culture comprising a sequence of nucleic acid codifying a protein having the sequence of factor G1753. In accordance with this reference, G1753 may be used for creating miniature forms of ornamental plants and for altering the signaling of sugar in plants. 
     In spite of the availability of some genes that have shown their ability to enhance the drought tolerance in a number of vegetal species, such as  Brassicaceae  and  Solanaceae , there exists the need to identify other genes having the ability to confer or enhance the drought tolerance when expressing in culture plants. 
     Biotic stresses as well as pathogens such as bacteria, fungi, virus or plagues such as insects, nematodes, are the most common and, typically several mechanisms protect the plants from most of these threats. However, in certain cases, the plants show a reaction susceptible to specific pathogens or plagues and are considered hosts for those pathogens or plagues. The interaction host-pathogen has been characterized by the concept gene by gene, where specific genes of the host plant and a pathogen/plague interact with each other to exhibit a susceptible or resistant reaction. Even though the molecular genetics of such interactions has been characterized in the last years, the use of such simple resistance genes has faced difficulties due to the versatile mutation of the pathogenic system that produce the diversity to surpass the resistance genes. Generally, the resistance genes belong to a few general classes of proteins formed by additional leucine-rich repeats and domains. Even though these genes and genetic interactions are interesting to study the plant-pathogen interactions, they are not ready to be used in the protection of the cultures against a wider diversity and range of pathogens. Another way of providing resistance is the use of genes that take part in the protection of plants against a varying range of pathogens by using mechanisms that do not depend on the recognition of plants and pathogens. This would confer a specific non-racial resistance which is wider, as it would confer resistance to a wider range of pathogens. 
     The development of plants tolerant to stress is a strategy that have a potential to resolve or remedy, at least, some of these problems. However, the traditional strategies of plants reproduction for developing new lines of plants that exhibit resistance or tolerance to these types of stress are relatively slow and require specific resistant lines to be crossed with the desired line. The limited resources of germplasm for tolerance to the stress and the incompatibility in the crossings between species of plants remotely related represent important problems found in the conventional reproduction. 
     Apart from these problems, the tendency throughout the world is to consume non-transgenic products. 
     There exists the need, therefore, of an alternative system for drought resistance that may resolve the present problems of the art, a system applicable to any plant, a system that during drought periods may supply electrons and protons to the plants roots which is what generates the photolysis of water in those plants of oxygenic photosynthesis.

     DETAILED DESCRIPTION OF THE INVENTION 
     Therefore, the object of the present invention is to decrease the impact of drought on the performance of the cultures. 
     As we know, these cultures perform oxygenic photosynthesis, where the giver of electrons is water. At the photosystem II the water photolysis is made where the water molecule (H 2 O) rupture is produced by the oxidizing action of the pigment p680+ releasing two electrons (2e − ), two protons (2H + ) with the release of atomic oxygen (O) which will be combined with the oxygen of another water molecule and will be released as gaseous oxygen by the stomates. 
       H 2 O→2H + +2 e   − +1/2O 2  
 
     This invention comprises of a system of two components of radicular absorption that will provide electrons (e − ) to the transport of electrons and protons (H + ) to the transport of protons for the phases of light of the photosynthesis during water stress and droughts. 
     The first one is the component I, a liquid protonated fertilizer of equivalent degree NPK 0-0-0 +3.2S+0.8Zn+0.4Fe+0.3Mg+0.2H + , where, depending on the equivalent degree, N refers to % w/w of nitrogen, P refers to % w/w of phosphorous expressed in phosphorous pentoxide (P 2 O 5 ), K refers to % w/w of potassium, S refers to % w/w of sulphur, Zn refers to % w/w of zinc, Fe refers to % w/w of iron, Mg refers to % w/w of magnesium, H +  refers to % w/w of protons which is a liquid fertilizer of radicular or foliar absorption providing protons (H + ) together with enzymatic activators micro elements and, optionally, nitrogen or nitrogen and phosphorous, or nitrogen and sulphur together with glucose and L-tirosine as metabolic activator; and 
     a component II which is a system of electrodes that generates an electric current that provides electrons (e − ) of radicular absorption. 
     According to the present invention, the following provided to the plant by radicular absorption: 
     i)—electrons (e) and protons (H + ) to compensate the water photolysis to keep the photosystems operating and to keep the ATP synthase and the generation of energy (ATP). 
     ii)—Magnesium cations (Mg 2+ ), ferrous iron (Fe 2+ ), zinc (Zn 2+ ) and sulphate anions (SO 4   2− ) as activators of the enzymes catalase and ribulose-1,5-biphosphate carboxilase oxygenase (RuBisCo9 and for the synthesis of chlorophyll achieving a greater photosynthetic efficacy. The sulphate anion (SO 4   2− ) is important for the protein synthesis. 
     iii)—Additionally, nitrogen (N) as the most important nutrient in the nutrition, production of biomass, being required by cultures as corn, wheat, sorghum, oats, barley and rice. 
     iv)—Additionally to the nitrogen, phosphorous (N, P) as important nutrient for the storage and transference of energy, particularly required by the soya bean culture. 
     v)—Additionally to the nitrogen, in some embodiments of the invention, sulphur (N, S) which is important for the proteins synthesis together with glucose (C 6 H 12 O 6 ) as source of energy and L-tirosine ((C 9 H 11 NO 3 ) as metabolic activator, being this combination suitable for an application via foliar on any culture such as soya bean, corn, wheat, sorghum, oats, barley and rice. 
     Particularly, the combination of i) and ii) allows obtaining an activator of catalase enzymes and RuBisCo, and for the synthesis of chlorophyll with magnesium and iron that gets a better absorption of solar energy increasing the activity of the photosynthesis and producing a plant with greater metabolic activity and greater efficiency in the photo acyclic phosphorilation by excess of electrons, as with the same number of sun photons, having a radicular electronic (e − ) stimulation and introducing protons (H + ) to compensate the water photolysis and to keep the photosystems operating, the excess of protons is used to keep the enzyme ATP synthase and the generation of energy (ATP) active which are necessary to keep the photosynthesis. 
     The present invention is applicable to the plants of C4 photosynthesis such as corn, sorghum, tomato, among others, as well as to plants of C3 photosynthesis such as wheat, soya bean, barley, rice, among others. 
     The component I of the proposed system is a liquid protonated fertilizer of equivalent degree NPK 0-0-0 +3.2S+0.8Zn+0.4Fe+0.3Mg+0.2H + . 
     This product of radicular absorption provides the necessary protons (H + ) for the generation of ATP and the zinc cation (Zn 2+ ) operating as radicular fertilizer of essential importance in the development of the culture, being zinc a metallic activator of the enzymes and taking part in the synthesis of the indoleacetic acid. It also performs electric operations before its radicular absorption, catalizing the Zn/Cu stack, in the diffusion of electrons on the soil. The magnesium cation (Mg 2+ ) performs electric operations at the beginning and fertilizing operations of nutrition when being adsorbed by the root. The most important function in the plants is to be a part of the chlorophill molecule, so it is actively involved in the photosynthesis process. However, in this role, only from 15 to 20% of the total magnesium of the leaves is involved. The magnesium activates more enzymes than any other element in the plant. It has important enzymatic actions, specially related to the process of CO 2  fixation. 
     In effect, the magnesium specifically activates the enzyme ribulose 1,5 biphosphate carboxilase oxygenase (RuBisCo), increasing its affinity to incorporate CO 2 . That&#39;s why the positive effect of the magnesium in the assimilation of CO 2  and the associated processes such as the production of sugars and starch. It also takes part in a series of vital processes for the plants requiring energy, such as the photosynthesis, breathing, and synthesis of macromolecules such as carbohydrates, proteins and lipids. 
     It has also an important structural role in the pectins, though in a very lesser amount of calcium and, lastly, it is an integral part of the ribosome. 
     The sulphate ion (SO 4   2− ) has several functions: enhances the efficiency of the nitrogen, is indispensable for the synthesis of amino acids containing sulphur and influences over the total synthesis of the proteins, important active enzymes in the energetic metabolism and that of the fatty acids. It is a component of the protein of the chloroplast, is a component of the B1 vitamin, present in the cereal grains, and is important in the production of substances such as phytoalexin, glutathione, necessary in the mechanisms for the defense of the plant. On the soil, it takes part in the exchange of aluminum phosphates, iron and calcium to get an increased availability of these elements in the plants, specially the essential elements such as iron and calcium. All this is always controlled so as not to compete with the magnesium absorption.

     The component II of the system, according to the present invention, is an electric circuit formed by two buried electrodes that form an antenna with the wire netting of the batch.
     Anode: zinc Zn→Zn 2+ +2e −  0.760 V oxidation   Cathode: copper Cu 2+ +2e − →Cu −0.340 V reduction   

     The zinc anode is a wire of zinc of 1.7 to 5 mm of diameter which is buried at a determined depth into the soil in a linear way, using an agricultural tool manufactured for this purpose, having a disk furrow opener, a wire attachment, which is supplied with a roll at the top, a dead furrow and a leveller wheel. This agricultural element is dragged by a tractor, generating a continuous anode. The cathode of wire of copper is from about 1.7 to about 5 mm of diameter and is placed in the same way as the anode, parallel thereto, in the other end of the field. 
     The depth to which the electrodes are buried depends on the type of culture, particularly it is related to the development of the culture roots to be stimulated. In wheat and soya bean, for example, depths of electrodes comprising a range among 3 to 7 cm may be used. For corn, the depth which is on the order of 7 cm is suitable. There is no limit of separation between both electrodes. This is shown in  FIGS. 2 a    and  2   b.    
     For example, the zinc anode is arranged at the West of the cultured batch and the copper cathode is at the East. In this way, the electrons will have, then, an orientation of circulation from West to East among the sides of the cultured batch, in such a way that they cross along with the lines of the magnetic field of the soil, generating a current of electrons on the order of μA an equivalent to 1.6×10 11  electrons, which are sufficient to supply the current of electrons necessary to replace the water photolysis of the photosystem II. 
     In a preferred embodiment of the invention, the south end of the zinc anode binds to one or several wires of the south wire netting and the north end of the copper cathode joins to one or several wires of the north wire netting, thus generating a kind of antenna that captures energy from the environment, of the atmosphere, such as static, among others, according to what is shown in  FIG. 2   a.    
     The arrangement of the antenna was achieved from a trial in a pot where wires of about 25 cm of length in an L form were used, they were buried at about 7 cm and the large part was left as an antenna to carry out the measurements of the current intensity in the trial. With this arrangement, a surprisingly unexpected result was obtained when by cutting said antennas the plants got dry in a very few days and those that remained operating were kept green and with resistance to drought. 
     Also, another object of the present invention is an agricultural tool ( 1 ) to place the wires working as anode and cathode of a batch. 
     Said agricultural tool ( 1 ) is a machine designed to put a wire working as electrode on the soil and then to cover it. This machine may be designed in a three points version or for dragging 
     Said agricultural machine ( 1 ) has a disk furrow opener ( 2 ), a wire winding ( 3 ), which is supplied with a reel ( 4 ), arranged at the top of the tool ( 1 ) and a dead furrow ( 5 ), constituted by two disks which are inclined and faced to each other and a leveller wheel ( 6 ), wherein the anode is a zinc wire and the cathode is a copper wire. 
     The elements constituting the tool ( 1 ) are assembled on a hinged structure or chassis ( 7 ) that may take a semi lateral working position, which allows the task to be carried out near the fence. 
     The first operation consists of penetrating the soil and opening a furrow where the electrode is being placed as the tool ( 1 ) moves forward. 
     At the top there exist two axis ( 8 ) that allow arranging each reel ( 4 ) where the electrodes are wrapped. 
     The wrapped electrodes are guided and pass through a wire winding ( 3 ), which role is to guide the electrode up to its final arrangement in the furrow without damage. 
     The land at the sides of the furrow is covered by two dead furrow wheels ( 5 ) which are inclined allowing the coverage of the electrode within the furrow with the possibility of being adjusted at a determined height. 
     At the last stage of the process of installation of the electrodes, the tool ( 1 ) levels the land that was removed with a leveller wheel ( 6 ) located at the rear part thereof. 
     Therefore, the agricultural tool ( 1 ) for placing a wire in a field comprises a structure or horizontal chassis ( 7 ) comprising anchorages ( 9 ) at the front end to bind together the tool ( 1 ) to a motorized vehicle, above the chassis ( 7 ) there are two supports ( 10 ) which are symmetrically and transversally assembled in line and at the same height with axis ( 8 ) that hold reels ( 4 ), where the wires that constitute the electrodes are wrapped, and below said reels ( 4 ) and in the middle of the chassis ( 7 ) a wire winding ( 3 ) is assembled for the wire to pass as the tool ( 1 ) moves forward along the field. 
     Below the chassis ( 7 ) and at the front of the tool ( 1 ), a furrow opener ( 2 ) in the form of an U is centrally assembled, behind this opener two dead furrow disks ( 5 ) are assembled inclined and faced in V and behind these disks a leveller wheel ( 6 ) is assembled which levels out the furrow already closed, where the dead furrow disks ( 5 ) are regulated in height. 
     The anchorages ( 9 ) in front of the chassis are located at the sides and enable the tool ( 1 ) to be anchored in a version of 3 points or in a version of dragging. 
     The version of 3 points is a combination of a superior bar o third point with two bars or inferior arms, all of which are brought together in their two ends and keeping together the agricultural tool ( 1 ) to the motorized vehicle, for example, a tractor, allowing said vehicle to be raised by means of an hydraulic system. Particularly, it may be assembled at the rear part of a motorized vehicle. 
     The dragging version allows the tool ( 1 ) to be dragged with a motorized vehicle, for example, a tractor, by means of a horizontal bar used for the vehicle to be fastened to the towed tool ( 1 ). 
     The chassis ( 7 ) is manufactured with a structural tube, preferably, of 40×80×4.75 cm, which is, preferably, painted with epoxy paint

     At a reactor with stirring, 10,000 dm 3  of component I (N, S) a liquid foliar protonated nitrogen sulphurized with metabolic and enzymatic activators were manufactured. 
     A stainless steel reactor of 316 was loaded with 4,000 dm3 of demineralised water, it was provided with an axis with a stirrer disk of four blades which caused a stirring at 1,000 rpm and 1,500 kg of ammonium sulphate were slowly added and stirring was kept. Next, 1,400 kg of glucose with stirring was added, 700 kg of ethoxylated lauryl alcohol of 7 mols OE were added. Next, 330 kg of L-tirosine previously dissolved in 2,000 kg of hydrochloric acid 2 N also under stirring were added. Furthermore, 70 kg of zinc oxide with stirring were added. 
     It was brought to a final volume of 10,000 dm 3  with demineralised water and stirring was kept during 25 minutes. The absence of a precipitate or insoluble material was controlled. Then, the solution was filtered in a vertical filter with a mesh of 300 microns and then the filtering operation was repeated with a mesh of 1 micron. 
     Example 5: Trial of Optimum Cartesian Orientation of the Component II 
     The trial consisted of plastic pots, all of them of the same size of 10 cm of diameter, 7.85×10 −3  m 2  containing 4 plants of wheat at the same vegetative stage. Plants were irrigated during 1 day and then water was suspended during 10 days and measurements were taken. 
     On day 1 of the trial the zinc and copper electrodes in the form of an L were buried in each end of the pot in a parallel way with the antennas upwards as it is shown in  FIG. 13 , with a north and south orientation, at a depth between 3 and 4 cm. 
     The trial consisted of determining, if any, an optimum Cartesian position of the component II, for which the emf (electromotive force) of the electrodes was measured as well as the current flow at the four cardinal points by rotating the pot in order to direct the zinc electrode to the East, North, West and South.

     As it can be seen in tables 1 and 2, the component II works in any of the four directions, getting the greatest values of emf and current flow with the orientation of the zinc electrode to the East and the copper electrode to the West, being, therefore, this last one the optimum orientation of operation of the component II. 
     Example 6: Trial of the Component II, an Electric Circuit Formed by Electrodes Zn/Cu 
     Trials were made in order to determine the behavior of the current recirculated in the land, points of energy collection and if it is feasible, applying pre-established formulas such as, for example, the Ohm&#39;s Law. 
     At an area of the field of about 20 m 2  of surface, where only grasses of 5 by 4 meters appear, voltages and currents got from the land were tested with 2 wire electrodes, one of zinc and the other one of copper to generate an emf, and another of zinc in order to take data based on the distances, taking as a reference point the negative electrode. 
     The electrodes used were buried at a depth on the order of 5 cm. 
     The time of the trial performance was the same moment as the one on which the component I was applied, and up to the senescence of the culture. 
     The conditions for the trial were the following: the temperature of the land at 10 cm of depth was of 24° C.; the linear distance among injector electrodes (patterns) was of 4 meters, the current of shortcircuit was of 0.58 μA; and the voltage between the terminals without load (emf) A-E was of 370 mV. 
     
       
         
         
             
             
         
       
     
     By placing among the electrodes a resistance R near 0 Ohm (Ω) the following data was obtained:

     Conclusions: As from the results obtained, it may be deduced that: 
     1—the land behaves as a enormous resistance. 
     2—It is acceptable to apply the Ohm&#39;s Law for approximate calculations in this type of trials. 
     Example 7: Trial of the Electric Behavior of the Electroprotonic Irrigation System in a Batch of Late Maturing Corn 
     Trials were made in order to determine the behavior of the current recirculated in the land in a corn batch. To this effect, the electrodes were placed, according to the previously mentioned description of the component II and were monitored with a tester as shown in  FIGS. 3, 4   a ,  4   b  and  4   c . The voltage in millivolts (mV) and the current flow in microamperes (μA) were measured as from the date of sowing up to its senescence. Several rains were registered. In table 4 two examples of rains may be observed at 52 days at the vegetative stage and at 107 days at the flowering stage.

     Conclusions: The values of the current flow and of the voltage were increased during the rains, then they were slowly being stabilizing to their normal values at the vegetative stage of the plants, which were kept high at the flowering stage. For this last stage, greater values of current were observed up to the filling of grains, then at the senescence stage the values were negative. 
     Examples of Application 
     Example of Application 1: Trial of Resistance to Drought of the Corn Pioneer 1833 HX in Pots 
     The trial consisted of plastic pots, all of them of the same size of 10 cm of diameter, 7.85×10 −3  m 2  containing 2 plants of corn Pioneer 1833 HX each at the same V3 vegetative stage. The trial was made in triplicate. Plants were irrigated during 3 days and then water was suspended during 8-10 days in pots  1  and  2 , and it was kept in pot  3 . 
     The pot  1  at the left of the  FIG. 5 a    is the witness pot, it was kept without irrigation during a period of 8-10 days. 
     The pot  2  at the center of the  FIG. 5 a    is the pot with the electroprotonic irrigation system, without irrigation during a period of 10 days. According to the image, on day 1 of the trial the zinc and copper electrodes in the form of an L, were buried, the electrode in the form of an L was folded, the short part was buried at 7 cm of depth and the large part of the L was left as an antenna, at the ends of the pot with East and West orientation, respectively. In this way, the component II was positioned. 
     The pot  3  at the right of  FIG. 5 a    is the pot with irrigation where water on the order of 5 cm 3  was applied per day with a pipette to each plant of said pot near the root. 
     The component I (N), a liquid protonated nitrogenous fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H + , was applied to the three pots at a dose on the order of 300 kg per hectare (240 mg/pot) so that no difference appears in the nutrition of the plants due to the micronutrients and nitrogen that this component has in its formulation apart from the protons. 
     After this period, a qualitative visual “score of drought” of 0-6 was assigned in order to register the degree of visible symptoms of stress due to drought. A score of “6” corresponded to non-visible symptoms, while a score of “0” corresponded to extreme withering and that the leaves had a “crunchy” texture. At the end of the drought period, the pots were irrigated again and were scored after 5-6 days; the number of surviving plants were counted in each pot and the proportion of total plants was calculated in the pots that survived. 
     The results obtained were the following: 
     The pot  1  was assigned, after the drought period, a score of 1, none of the plants survived when they were irrigated again and the final score was 0. 
     The pot  2  was assigned, after the drought period, a score of 5, and all the plants survived when they were irrigated again obtaining a final score of 6. 
     The pot  3  was assigned, after the trial period, a score of 6. 
     Conclusions: It was observed that the electroprotonic irrigation system gave a substantially unexpected result due to the fact that the “score of drought” of 6 at the end of the trial of the corn plants was comparable to the one obtained with regular irrigation. This showed a noticeable difference with respect to the corn plants under water stress due to drought. 
     Example of Application 2: Trial of Resistance to Drought of the Soya Bean Nidera NS 5258 in Pots 
     The trial consisted of three plastic pots, all of them of the same size of 10 cm of diameter, 7.85×10 −3  m 2  containing 2 plants of soya been Nidera NS 5258, each at the same V2 vegetative stage. The trial was made in triplicate. Plants were irrigated during 3 days and then water was suspended during 18-20 days in pots  1  and  2 , and it was kept in pot  3 . 
     The pot  1  at the left of the  FIG. 5 b    is the witness pot, it was kept without irrigation during a period of 18-20 days. 
     The pot  2  at the center of the  FIG. 5 b    is the pot with the corresponding electroprotonic irrigation system, without irrigation during a period of 18 -20 days. According to the image, on day 1 of the trial the zinc and copper electrodes in the form of an L, were buried, the electrode in the form of an L was folded, the short part was buried at 7 cm of depth and the large part of the L was left as an antenna, at the ends of the pot with East and West orientation, respectively. In this way, the component II was positioned. 
     The pot  3  at the right of  FIG. 5 b    is the pot with irrigation where water on the order of 5 cm 3  was applied per day with a pipette to each plant of said pot near the root. 
     The component I (N, P), a liquid protonated nitrogen phosphorous fertilizer of equivalent degree NPK 4-18-0 +5S+0.8Zn+0.4Fe+0.3Mg+0.33H+ was applied to the three pots at a dose on the order of 100 kg per hectare (78.5 mg/pot) so that no difference appears in the nutrition of the plants due to the micronutrients that this component has in its formulation apart from the protons. 
     After this period a qualitative visual “score of drought” of 0-6 was assigned in order to register the degree of visible symptoms of stress due to drought. A score of “6” corresponded to non-visible symptoms, while a score of “0” corresponded to extreme withering and that the leaves had a “crunchy” texture. At the end of the drought period, the pots were irrigated again and were scored after 5-6 days; the number of surviving plants were counted in each pot and the proportion of total plants was calculated in the pots that survived. 
     The results obtained were the following: 
     The pot  1  was assigned, after the drought period, a score of 4, all of the plants survived when they were irrigated again and the final score was 5. 
     The pot  2  was assigned, after the drought period, a score of 5, and all the plants survived when they were irrigated again obtaining a score at the end of the trial of 6. 
     The pot  3  was assigned, after the trial period, a score of 6. 
     Conclusions: It was observed that the electroprotonic irrigation system showed a completely unexpected result, the “score of drought” of 6 at the end of the trial of the soya bean plants was comparable to that of regular irrigation, showing a qualitatively detectable difference with respect to the soya bean plants under water stress due to drought. 
     Example of Application 3: Trial of Resistance to Drought of the Wheat in Pots 
     The trial consisted of three plastic pots, all of them of the same size of 10 cm of diameter, 7.85×10 −3  m 2  containing 4 plants of wheat BAGUETTE 601, each at the same vegetative stage 3 full tillering. The trial was made in triplicate. Plants were irrigated during 3 days and then water was suspended during 18-20 days in pots  1  and  2 , and it was kept in pot  3 . 
     The pot  1  at the left of the  FIG. 5 c    is the witness pot, it was kept without irrigation during a period of 18-20 days. 
     The pot  2  at the center of the  FIG. 5 c    is the pot with the corresponding electroprotonic irrigation system, without irrigation during a period of 18 -20 days. 
     On day 1 of the trial the zinc and copper electrodes in the form of an L, were buried, the electrode in the form of an L was folded, the short part was buried at 3 cm of depth and the large part of the L was left as an antenna, at the ends of the pot with East and West orientation, respectively. In this way, the component II was positioned. 
     The pot  3  at the right of  FIG. 5 c    is the pot with irrigation where water on the order of 5 cm 3  was applied per day with a pipette to each plant of said pot near the root. 
     The component 1 (N), a liquid protonated nitrogen fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H+ was applied to the three pots at a dose on the order of 350 kg per hectare (275 mg/pot) so that no difference appears in the nutrition of the plants due to the micronutrients that this component has in its formulation apart from the protons. 
     After this period a qualitative visual “score of drought” of 0-6 was assigned in order to register the degree of visible symptoms of stress due to drought. A score of “6” corresponded to non-visible symptoms, while a score of “0” corresponded to extreme withering and that the leaves had a “crunchy” texture. At the end of the drought period, the pots were irrigated again and were scored after 5-6 days; the number of surviving plants were counted in each pot and the proportion of total plants was calculated in the pots that survived. 
     The results obtained were the following: 
     The pot  1  was assigned, after the drought period, a score of 4, and all the plants survived when they were irrigated again and the score was 5. 
     The pot  2  was assigned, after the drought period, a score of 6, and all the plants survived when they were irrigated again obtaining a score at the end of the trial of 6. 
     The pot  3  was assigned, after the trial period, a score of 6. 
     Conclusions: It may be inferred that the electroprotonic irrigation system gave a completely unexpected result due to the fact that the “score of drought” of 6 at the end of the trial of the wheat plants was comparable to the one obtained with regular irrigation. This showed a qualitatively detectable difference with respect to the wheat plants under water stress due to drought. 
     Example of Application 4: Trial on a Field of Resistance to Drought in Corn 
     A trial was performed on a field of the agricultural establishment named Don Domingo located in Salto Grande, Santa Fe province, Argentina. The soil corresponds to class I of a very good productivity. Rains during the cycle of culture are shown in table 7; rains were regular during the cycle, but with periods of water stress due to drought in the flowering stage and of filling of grains. The experiment was made in a culture that was sowed by direct sowing (DS), at a distance of 52 cm between furrows, with soya bean as predecessor. Seeds of Pioneer 1833 HX were used. 
     The basic fertilization consisted of the application on the order of 70 kg/ha of monoammonium phosphate (MAP) and approximately 100 dm 3  of liquid fertilizer NTX 9N-12P-7S located in the sowing. As fertilization in V3 vegetative stage, the component I, a liquid protonated fertilizer of equivalent degree NPK 0-0-0 +3.2S+0.8Zn+0.4Fe+0.3Mg+0.2H + , was applied by blasting among furrows on the order of ascending doses of 0 kg, 100 kg, 200 kg and 300 kg per hectare. At the trial, a randomized complete-block design was used with three repeats and 8 treatments. The purpose of this trial was to demonstrate the tolerance/resistance to drought under the system of the present invention and to determine the dose of component I. A detail of the treatments is presented in the following table 5.

     Sowing was manually carried out, with stationary threshing of the samples. In an aliquot of the harvest, the components of performance, the number of grains (NG) per ear and per m 2  and the weight of one thousand grains (P1000) were analyzed. In order to study of the results an analysis of variance, comparisons of means and a correlation analysis were carried out. 
     The results obtained are summarized in table 8.

     Treatments T2, T3 and T4 were kept without electronic stimulation, varying the dose of the component I. Treatment T4 was the most effective of the three treatments, showing that the increase of the concentration of protons slightly increased the performance with respect to the witness T1, but it was not of significance. 
     Treatment T5 with respect to the witness T1, showed that the electronic stimulation is significantly important in the performance with an increase of 10%. 
     Treatments T6, T7 and T8 showed that the combination of the electronic stimulation and the ascending protonic gave a wonderfully unexpected result of up to 13% of increase in the performance with respect to witness T1. 
     Conclusions: The combination of the electronic stimulation and the protonic stimulation gave an increase in the performance of up to 13% with respect to witness T1, showing a clear resistance to water stress of the corn being treated. 
     Comparative Examples 
     Comparative Example 1: Trial of Resistance to Drought in Corn as Compared the Corn DEKALB DK 72-10VT3P Under Electroprotonic Irrigation with the Corn Resistant to Drought DEKALB DKC 5741 
     The trial was performed in 2 plastic pots of the same size of 10 cm of diameter, 7.85×10 −3  m 2  of surface, where the pot  1  contained 2 plants of corn DEKALB DK 72-10VT3P and the pot  2  contained 2 plants of corn DEKALB DKC 5741 resistant to drought and extreme heat, each of them in the same V3 vegetative stage. The trial was made in triplicate. The pots were irrigated during 3 days and then water was suspended during a period of 15 days. 
     The pot  1  at the left of  FIG. 9  is the pot corresponding to the electroprotonic irrigation system, without irrigation during a period of 15 days. According to the image, on day 1 of the trial the zinc and copper electrodes in the form of an L, were buried, with West and East orientation respectively, at a depth on the order of 7 cm. In this way, the component II was positioned. 
     The pot  2  at the right of  FIG. 9  was the pot corresponding to the corn seed DEKALB DKC 5741 resistant to drought. 
     The component I (N), a liquid protonated nitrogen fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H+ was applied to the two pots at a dose on the order of 300 kg per hectare (240 mg/pot) so that no difference appears in the nutrition of the plants due to the micronutrients that this component has in its formulation apart from the protons. 
     After this period, a qualitative visual “score of drought” of 0-6 was assigned in order to register the degree of visible symptoms of stress due to drought. A score of “6” corresponded to non-visible symptoms, while a score of “0” corresponded to extreme withering and that the leaves had a “crunchy” texture. At the end of the drought period, the pots were irrigated again and were scored after 5 days; the number of surviving plants were counted in each pot and the proportion of total plants was calculated in the pots that survived. 
     The results obtained were the following: 
     The pot  1  was assigned, after the drought period, a score of 6, and all the plants survived when they were irrigated again obtaining a score at the end of the trial of 6. 
     The pot  2  was assigned, after the drought period, a score of 4, and all the plants survived when they were irrigated again obtaining a score at the end of the trial of 5. 
     Conclusions: It may be inferred that the electroprotonic irrigation system showed a superior result, the “score of drought” of 6 at the end of the trial of the corn plants showed a clear difference with the genetically modified seed DEKALB DKC 5741 resistant to drought. 
     Comparative Example 2: Trial of Resistance to Drought in Corn as Compared the Corn DEKALB DK 4020 Under Electroprotonic Irrigation with the Corn Resistant to Drought KWS KEFIEROS FAO 700 
     The trial was performed in 2 plastic pots of the same size of 10 cm of diameter, 7.85×10 −3  m 2  of surface, where the pot  1  contained 2 plants of corn KWS KM 4020 and the pot  2  contained 2 plants of corn KWS KEFIEROS FAO 700 resistant to drought and to extreme heat, each of them in the same V3 vegetative stage. The trial was made in triplicate. The pots were irrigated during 3 days and then water was suspended during a period of 15 days. 
     The pot  1  at the left of  FIG. 10  was the pot corresponding to the electroprotonic irrigation system, without irrigation during a period of 15 days. According to the images, on day 1 of the trial the zinc and copper electrodes in the form of an L, were buried, with West and East orientation respectively, at a depth on the order of 7 cm. In this way, the component II was positioned. 
     The pot  2  at the right of  FIG. 10  was the pot corresponding to the corn seed KWS KEFIEROS FAO 700 resistant to drought. 
     The component I (N), a liquid protonated nitrogen fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H+ was applied to the two pots at a dose on the order of 300 kg per hectare (240 mg/pot) so that no difference appears in the nutrition of the plants due to the micronutrients that this component has in its formulation apart from the protons. 
     After this period a qualitative visual “score of drought” of 0-6 was assigned in order to register the degree of visible symptoms of stress due to visible drought. A score of “6” corresponded to non-visible symptoms, while a score of “0” corresponded to extreme withering and that the leaves had a “crunchy” texture.

     The results obtained were the following: 
     The pot  1  was assigned, after the drought period, a score of 5, and all the plants survived when they were irrigated again and the score at the end of the trial was of 6. 
     The pot  2  was assigned after the drought period a score of 4, and all the plants survived when they were irrigated again obtaining a score at the end of the trial of 5. 
     Conclusions: It may be inferred that the electroprotonic irrigation system showed a superior result, where the “score of drought” of 6 at the end of the trial of the corn plants KWS KM 4020 showed a clear difference with the genetically modified seed KWS KEFIEROS FAO 700 resistant to drought. 
     Comparative Example 3: Trial on a Field of Resistance to Drought in Corn as Compared the Corns Resistant to Drought DEKALB DKC 5741 and KWS KEFIEROS FAO 700 with the Hybrid Corns Non-Resistant to Drought KWS KM 4020 and DEKALB DK 72-10VT3P with the Application of Electroprotonic Irrigation 
     A trial was performed on a field of the agricultural establishment named Estancia Morelli at Correa, Santa Fe province, Argentina. The soil corresponds to class I of good productivity. Rains during the cycle of culture are shown in table 11, they were regular during the cycle and ascended to 502 mm, but with periods of water stress due to drought in the flowering stage and of filling of grains. The experiment was made in a culture that was sowed by direct sowing (DS), at a distance of 52 cm between furrows, with soya bean as predecessor. Corn hybrids DEKALB DKC 5741, KWS KEFIEROS FAO 700, KWS KM 4020 and DEKALB DK 72-10VT3P. were used. 
     The basic fertilization consisted of the application on the order of 100 kg/ha of monoammonium phosphate (MAP) at the time of the sowing. A fertilization at V3 vegetative stage was applied by blasting to furrows on the order of 350 kg of a liquid fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg, it was applied during treatments T1 and T3 so that no difference appears in the nutrition of the different corn hybrids due to the micronutrients that this component has in its formulation, apart from the protons, and the component I (N), a liquid protonated nitrogen fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H +  for treatments T2 and T4. At the trial, a randomized complete-block design was used with three repeats and 4 treatments. The purpose of this trial is to demonstrate the tolerance/resistance to drought under the system of the present invention as compared with the genetically modified seeds resistant to drought with a the basic fertilization in all treatments except in T2 and T4 where protons and electrons are added while in T1 and T3 there are no additions. A detail of the treatments performed are shown in the following table 9.

     Treatments T2 and T4 yielded the best performances, corresponding to the electroprotonic irrigation. 
     Treatment T2 rendered 6.9% of increase in the performance over treatment T1 of the genetically modified hybrid resistant to drought of the same seedbed KWS showing the efficacy of the system of the present invention over the genetically modified seeds resistant to drought. 
     Treatment T4 rendered 10.7% of increase in the performance over treatment T3 of the genetically modified hybrid resistant to drought of the same seedbed Monsanto DEKALB, showing the efficacy of the system of the present invention over the genetically modified seeds resistant to drought. 
     Conclusions: It may be arrived to the conclusion that the application of electroprotonic stimulation gives an increase of performance over the corn hybrid non-resistant to drought, over the genetically modified corns resistant to drought during the water stress caused by drought. 
     Comparative Example 4: Trial on a Field of Resistance to Drought in Corn as Compared the Hybrid Corns of Monsanto DK692 MG RR2 Syngenta NK 900 TDT6, Dow M515 Hx RR2 and Pioneer P2049 Y, with and without an Electroprotonic Irrigation System 
     A trial was performed on a field of the agricultural establishment named Estancia Morelli at Correa, Santa Fe province, Argentina. The soil corresponds to class I of good productivity. Rains during the cycle of culture are shown in table 15, they were regular during the cycle, but with periods of water stress due to drought in the flowering stage and of filling of grains. The experiment was made in a culture that was sowed by direct sowing (DS), at a distance of 52 cm between furrows, with soya bean as predecessor Corn hybrids Monsanto DK692 MG RR2, Syngenta NK 900 TDT6 Nidera Ax 870 MG and Pioneer P2049 Y were used. 
     The basic fertilization consisted of the application on the order of 100 kg/ha of monoammonium phosphate (MAP) that were applied at the time of the sowing. A fertilization in V3 vegetative stage was applied by blasting to furrows on the order of 350 kg of the component I (N), a liquid protonated nitrogenous fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H + . At the trial, a randomized complete-block design was used with three repeats and 8 treatments. The purpose of this trial is to demonstrate the tolerance/resistance to drought under the system of the present invention as compared with the genetically modified seeds resistant to drought. A detail of the treatments performed are shown in the following table 13.

     The component I (N), a liquid protonated nitrogen fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H+ was applied to each treatment at a dose on the order of 350 kg per hectare so that no difference appears in the nutrition of the different corn hybrids due to the micronutrients that this component has in its formulation apart from the protons. 
     The component II was placed in order to enable the electronic stimulation to be continuous with zinc and copper electrodes placed in the form as previously described here, that is, they were buried at about 7 cm of depth and put together to the wire netting of the East and West sides, respectively. 
     The analysis of the soil of the experimental site is shown in table 14, where representative results of the region are displayed.

     Sowing was manually carried out, with stationary threshing of the samples. On an aliquot of the harvest, the components of performance, the number of grains (NG) per ear and per m2 and the weight of 1,000 grains (P1000) were analyzed. In order to study of the results an analysis of variance, comparisons of means and a correlation analysis were carried out. 
     The results obtained are shown in the following table 16.

     Treatments T5 to T8 rendered the greatest performances, being all of them corresponding to the treatment by electroprotonic irrigation. 
     Treatment T5 rendered an increase in the performance of 14% over treatment T1; that is, the same hybrid Monsanto DK692 MG RR2 under the same conditions gave a noticeable increase of performance with the application of electroprotonic irrigation. 
     Treatment T6 rendered an increase in the performance of 12% over treatment T2; that is, the same hybrid Syngenta NK 900 TDT6 gave a noticeable increase of performance with the application of electroprotonic irrigation. 
     Treatment T7 rendered an increase in the performance of 11% over treatment T3; that is, the same hybrid Nidera Ax 870 MG gave an increase of performance with the application of electroprotonic irrigation. 
     Treatment T8 rendered an increase in the performance of 10% over treatment T4; that is, the same hybrid Pioneer P2049 Y under the same conditions gave an increase of performance with the application of electroprotonic irrigation. 
     Conclusions: It may be observed that the combination of the electroprotonic stimulation renders an increase in the performance over the corn hybrids in this comparative trial, being directly proportional to the potential of the hybrid. It may be estimated that as the potentials of the yields of the new commercial hybrids increase, the present invention will be more effective. 
     Comparative Example 5: Trial on a Field of Resistance to Drought in Wheat as Compared the Wheat Baguette 801 Premium, ACA 307, KLEIN Gladiador and SY 110 with and without an Electroprotonic Irrigation System 
     A trial was performed on a field of the agricultural establishment named Estancia Chamorro at Correa, Santa Fe province, Argentina. The soil corresponds to class I of good productivity. Rains during the cycle of culture are shown in table 19 where the existence of water stress during the period of trial is shown. The experiment was made in a culture that was sowed over crop residues of soya bean of first class, at a distance of 20 cm between furrows. Baguette 801 Premium, ACA 307, KLEIN Gladiador and SY 100 were used. 
     The basic fertilization consisted of the application on the order of 80 kg/ha of monoammonium phosphate (MAP) that were applied at the time of the sowing. A fertilization under tillering was applied on the order of 370 kg of the component I (N), a liquid protonated nitrogenous fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H + . At the trial, a randomized complete-block design was used with three repeats and eight treatments. The purpose of this trial was to demonstrate the tolerance/resistance to drought under the system of the present invention as compared with the same varieties without application of the mentioned system. A detail of the treatments performed are shown in the following table 17.

     The component I (N), a liquid protonated nitrogen fertilizer of equivalent degree NPK 27-0-0 +3.20S+0.3Zn+0.1Fe+0.1Mg+0.20H+ was applied to each treatment at a dose on the order of 370 kg per hectare so that no difference appears in the nutrition of the different varieties of wheat due to the micronutrients that this component has in its formulation apart from the protons. 
     The component II was placed in order to enable the electronic stimulation to be continuous with zinc and copper electrodes placed in the form as previously described here, that is, they were buried at about 7 cm of depth and put together to the wire netting of the East and West sides, respectively. 
     The analysis of the soil of the experimental site is shown in table 18, where representative results of the region are displayed.

     Comparative Example 6: Trial on a Field of the Performance, in a Regular Year, of Soya Bean as Compared the Varieties of the Short Cycle III ACA 3535 GR and DM 3312 and the Large Cycle III SRM 3970 and SP 3×7, with and without the Electroprotonic Irrigation 
     A trial was performed on a field of the agricultural establishment named Estancia Don Domingo at Correa, Santa Fe province, Argentina. The soil corresponds to class I of good productivity. Rains during the cycle of culture are shown in table 23. Said rains were regular during the cycle of trial. The experiment was made in a culture that was sowed over crop residues of corn, at a distance of 52 cm between furrows. Soya bean was used as compared the varieties of the short cycle III ACA 3535 GR and DM 3312 and the large cycle III SRM 3970 and SP 3×7 with each other, with and without the electroprotonic irrigation At the trial, a randomized complete-block design was used with three repeats and eight treatments. The purpose of this trial was to demonstrate the performance under the application of the electroprotonic irrigation system of the present invention as compared with the same varieties without the application of said system. A detail of the treatments performed are shown in the following table 21.

     The component I (N, P), a liquid protonated nitrogen phosphorous fertilizer of equivalent degree NPK 4-18-0 +5S+0.8Zn+0.4Fe+0.3Mg+0.33H+ was applied to each treatment at a dose on the order of 100 kg per hectare so that no difference appears in the nutrition of the different varieties of soya bean due to the micronutrients that this component has in its formulation apart from the protons. 
     The component II was placed in order to enable the electronic stimulation to be continuous with zinc and copper electrodes placed in the form as previously described here, that is, they were buried at about 7 cm of depth and put together to the wire netting of the East and West sides, respectively. 
     The analysis of the soil of the experimental site is shown in table 22, where representative results of the region are displayed.

     Treatments T5 and T6 rendered greater performances, on the order of 8 and 7%, respectively, with respect to the same variety without electroprotonic irrigation. 
     Treatment T5 rendered an increase in the performance of 8% over treatment T1; that is, the same soya bean ACA 3535 GR under the same conditions gave a noticeable increase of performance with the application of electroprotonic irrigation. 
     Treatment T6 rendered an increase in the performance of 7% over treatment T2; that is, the same soya bean DM 3312 gave an important increase of performance with the application of electroprotonic irrigation. 
     Treatment T7 rendered an increase in the performance of 5% over treatment T3; that is, the same soya bean SRM 3970 gave an increase of performance with the application of electroprotonic irrigation. 
     Treatment T8 rendered an increase in the performance of 5% over treatment T4; that is, the same soya bean SP 3×7 under the same conditions gave an increase of performance with the application of electroprotonic irrigation. 
     Conclusions: It may be observed that the combination of the electroprotonic irrigation renders an increase in the performance over the same varieties of soya bean in this comparative trial of application, in a year of regular rains. This shows that the system may be applied in all the environmental conditions, increasing, in each case, the performance and generating profitability to the producer in regular years, and profitability and security in years of drought or water stress. 
     Comparative Example 7: Trial on a Field of the Performance, in a Year with Water Stress, of Soya Bean as Compared the Varieties of the Short Cycle III ACA 3535 GR and DM 3312 and the Large Cycle III SRM 3970 and SP 3×7, with and without the Electroprotonic Irrigation Using the Component I (N, S) via Foliar 
     A trial was performed on a field of the agricultural establishment named Estancia Don Domingo at Correa, Santa Fe province, Argentina. The soil corresponds to class I of good productivity. Rains during the cycle of culture are shown in table 25. Said rains were scarce during the cycle of trial. 
     The experiment was made in a culture that was sowed over crop residues of corn, at a distance of 52 cm between furrows. Soya bean was used as compared the varieties of the short cycle III ACA 3535 GR and DM 3312 and the large cycle III SRM 3970 and SP 3×7 with each other, with and without the electroprotonic irrigation At the trial, a randomized complete-block design was used with three repeats and eight treatments. The purpose of this trial was to demonstrate the performance under the application of the electroprotonic irrigation system of the present invention as compared with the same varieties without the application of said system. A detail of the treatments performed are shown in the following table 25.

     Treatments T5 and T7 rendered greater performances, on the order of 32.9 and 32.1%, respectively, with respect to the same variety without electroprotonic irrigation. 
     Treatment T5 rendered an increase in the performance of 32.9% over treatment T1; that is, the same soya bean ACA 3535 GR under the same conditions gave a noticeable increase of performance with the application of electroprotonic irrigation. 
     Treatment T6 rendered an increase in the performance of 31.4% over treatment T2; that is, the same soya bean DM 3312 gave an important increase of performance with the application of electroprotonic irrigation. 
     Treatment T7 rendered an increase in the performance of 32.1% over treatment T3; that is, the same soya bean SRM 3970 gave a significant increase of performance with the application of electroprotonic irrigation. 
     Treatment T8 rendered an increase in the performance of 31.2% over treatment T4; that is, the same soya bean SP 3×7 under the same conditions gave a noticeable increase of performance with the application of electroprotonic irrigation. 
     Conclusions: It may be observed that the combination of the electroprotonic irrigation renders an increase in the performance over the same varieties of soya bean in this comparative trial in a year with water stress. This shows that the system may be applied in all the unfavorable environmental conditions generating profitability and security in years of water stress.
