Authors: Ferrer Rosa , Hernández-Andara Adalsa , Ortega Pertuz Ana Isabel
Published: February 2020

Introduction: air cells in the articular tubercle and the discontinuity of the cortical mandibular fossa are sites of minimal resistance, favoring the extension of various pathologies, which should be differentiated from similar processes involving bone expansion/destruction. The aim of this study was to assess pneumatized articular tubercle (PAT) and discontinuity of the temporal bone’s mandibular fossa (DMF) through computed tomography (CT), focusing on its distribution by age, sex, and laterality. Methods: 200 CT studies including both temporomandibular joints (TMJ) were selected, recording age, sex, presence/absence of PAT and DMF and their laterality. Results: 19% of patients had some anatomical variants. PAT was seen in 15.5% of cases (n = 31), 21 females (67.74%) and 10 males (32.26%). DMF was seen in seven cases (3.5%), all in females. 51.62% of PAT were bilateral, and 85.71% of DMF were unilateral. Conclusions: the sample under study has a high prevalence of PAT. DMF should be considered in the evaluation of TMJ by CT, with this being the method of choice to assess bone structures and air spaces in temporal bone.

Introduction: early childhood caries (ECC) is a public health problem. Recognizing caries patterns in affected children can help improve oral health programs focused on the preschool population. The aim of this study was to identify caries patterns in 3- to 5-year-old children in a low to middle-low socioeconomic area. Methods: a calibrated dentist recorded caries lesions using ICDAS criteria in 548 children attending four day-care centers in a low to middle-low socioeconomic area. ECC and S-ECC prevalence and theproportion of affected teeth/surfaces by lesion type for homologous teeth were calculated. Results: a totalof 419 (76.5%) and 238 (43.4%) children had ECC and S-ECC, respectively. Average dmft was 3.7±3.7 and average affected surfaces were 5.8±7.7. Occlusal surfaces showed the highest caries experience, varying from 17.7% to 36.1%, showing statistical significance when compared to other molar surfaces. The uppersmooth anterior surfaces were affected from 0.2% to 17.2%, while lower smooth anterior surfaces showed values between 0.0% and 6.8%. The percentage of dental caries experience in second molars varies from 37.1% to 42%, while in lower central and lateral incisors the values range from 1.8% to 4.6%. Conclusion:the specific caries pattern in preschool children with high prevalent ECC from a middle-low-income area indicate the need to design programs aimed at detecting early sings of dental caries in specific locations, as well as disease control strategies.

Published: February 2020

Globally, natural disasters have caused a large scale of damage and destruction every year, affecting millions of people, the economy, and development – and developing countries are the most severely affected. Odisha is one of India’s most disaster-prone states. This study explores the effects of, and resilience to, cyclones, floods, droughts, and heatwaves in Odisha, and identifies government strategies that help mitigate these natural disasters. We mainly used primary data collected through a qualitative study undertaken from April 2017 to June 2017 in three districts of Odisha. We conducted in-depth interviews and focus group discussions with community members and key stakeholders at different levels. In addition, our study analyzed secondary data on natural disasters using DesInventar, a disaster information management system data source. The findings show that floods, cyclones, and drought in recent years, along with heatwaves and lightning, have severely affected the people of Odisha. The impacts of these natural disasters are calamitous – particularly on livelihoods, food security, health, water, and sanitation. These natural disasters, which have affected agriculture, fisheries, prawn cultivation, roadside vendors, and daily wage laborers, have both short- and long-term effects on the livelihoods of people in Odisha, leaving them with scarce employment opportunities. The vulnerable and marginalized sections of the population have been the most severely affected, and common coping mechanisms have included selling off livestock, borrowing food, taking loans and mortgages, and migration. The government’s measures/programs, such as an Early Warning System, Public Distribution System, Multipurpose Cyclone Rehabilitation Centers, Seasonal Residential Care Centers, and Indira Awas Yojana, play a major role in mitigating the effect of disasters among rural communities. Our study indicates that natural disasters have impacted the population of the state socioeconomically, physically, and psychologically. The effect on livelihoods, directly and indirectly, exacerbates income, food security, and health. There is an urgent need to focus on reducing people’s underlying vulnerabilities by taking proactive measures, engaging the community in decision-making, and generating alternative and sustainable livelihoods.
The Eucharist as a Sacrament of Christian Initiation: Historical-Liturgical Aspect

Eucharystia jako sakrament inicjacji chrześcijańskiej — aspekt historycznoliturgiczny

Autor artykułu podejmuje problematykę miejsca Eucharystii w inicjacji chrześcijańskiej w aspekcie historycznoliturgicznym. Zwraca uwagę na obecną w pierwszym tysiącleciu zasadniczą świadomość jedności i właściwej kolejności sakramentów inicjacji chrześcijańskiej: chrzest –bierzmowanie–Eucharystia. Jej zanik zauważa na przełomie XII i XIII wieku wraz z odejściem od praktyki Komunii św. dzieci. Wskazuje, że w okresie potrydenckim doszło do odwrócenia kolejności udzielania sakramentów inicjacji chrześcijańskiej: chrzest–Eucharystia–bierzmowanie, a ten stan utrwalił dekret Quam singulari (1910), który jeszcze bardziej oddzielił od siebie te sakramenty. Autor zwraca uwagę, że powstałe po Soborze Watykańskim II dwa modele inicjacji chrześcijańskiej związane są z Ordo baptismi parvulorum (1969), określającym praktykę chrztu dzieci, po którym po kilku latach następuje I Komunia, a w późniejszym czasie – bierzmowanie, oraz z Ordo initiationis christianae adultorum (1972), dotyczącym przygotowania do bierzmowania i Eucharystii dorosłych. Odwołując się do poglądów Salvatore Marsilego, autor artykułu dokonuje oceny modeli. Za pełnowartościowy uznaje ten związany z Ordo initiationis christianae adultorum, w którym punktem docelowym jest Eucharystia. Model ten zachowuje teologiczną kolejność sakramentów i traktuje Eucharystię, a nie bierzmowanie, jako dopełnienie i szczyt inicjacji chrześcijańskiej. Pozwala także na właściwe określenie chrztu jako sakramentu włączającego w misterium zbawienia, wymagającego jednak bierzmowania i Eucharystii do pełnego włączenia w rzeczywistość Kościoła.

Authors: Bolaños Ceballos Fernando , De Keijzer Benno
Published: February 2020

El objetivo es describir y analizar la determinación social del malestar psicológico y el estrés en dos grupos de hombres de la Ciudad de México que asistían a programas reeducativos por violencia familiar. Para ello, se realizó un estudio no experimental, transversal, descriptivo con metodología cualitativa y enfoque interpretativo, en el que se aplicó un cuestionario y se realizaron grupos focales. Los síntomas de estrés reportados fueron dolores musculares; insomnio y pesadillas; náuseas, dolor de estómago e indigestión; dolores de cabeza, mareos, irritabilidad o mal humor. Los principales problemas que podrían estar generando esta sintomatología serían la economía personal y familiar; la salud de ellos y sus familiares y los malestares mentales, entre otros aspectos. Existen diferencias relacionadas con las condiciones de vida y los efectos de la violencia doméstica. Los abordajes que solo consideran la masculinidad hegemónica o el género para el trabajo con varones en sus diferentes condiciones y problemáticas, sin considerar la desigualdad social y, en especial, las condiciones de vida, pueden ser insuficientes para explicar y modificar las causas de las afectaciones generadas y experimentadas por los varones.

Published: February 2020

The article presents the results of theoretical studies of the technological process of operation of multi-blade working bodies of rotary type, intended for the distribution of solid organic fertilizers. To determine the length of the blades of the last row of rotors, and accordingly the overall dimensions of the spreader, theoretical dependences of the range of fertilizer particles on the radius of the blades are obtained, which made it possible to determine the size of the blades that provide the required performance of the rotary spreader. Considering the uniform distribution of fertilizer particles over the sieving width, the dependences of the “limiting” zone of loading of the blades (the maximum thickness of the layer of fertilizers captured by one blade) on the angle of their inclination at different lengths of the blades were obtained, which showed that when applying fertilizers with medium and large doses, several rows of blades. Computational experiments were carried out, during which, the number of rows of blades and the ratio of the lengths of the blades of different rows were determined to obtain the smallest unevenness depending on different doses of fertilizer application. As a result of mathematical modeling, the dependences of the working insertion width on the angle of inclination of the blades of the rotor rows relative to the radial position are obtained for various second-time supply of material, using which rational values of the angle of inclination of the blades are found.

Published: February 2020

The article discusses the thermal processes occurring in a biogas plant in which the mixing device and the heating element are combined into one node, which allows to heat and maintain a given temperature regime more evenly due to the rotation of the heat exchanger and heat transfer to the biomass throughout the entire bioreactor. Required to operate the unit in a thermophilic mode, after its withdrawal to the working state, the heat output is determined by the heat loss of the plant itself and flow with increasing litter temperature to the temperature of the thermophilic mode, which can be described by thermodynamic equations. As a result of theoretical studies, factors have been identified that allow determining the distribution of biomass temperature over the entire volume of the digester. Studies were conducted to obtain data on the impact of the main parameters (design, kinematic and geometric) of a biogas plant and a heat exchanger-agitator on the quality indicators of its work, as well as the thermal processes occurring in it. The theoretical temperature homogeneity of the mixed medium is achieved by combining the heat exchanger and the mixing device into one node, the design and technological parameters of which characterize the intensity of the forced movement of fermented waste, changing the value of thermal conductivity, and finding the temperature field is the main task of the analytical theory of thermal conductivity applicable to the processes occurring in the bioreactor installation.
Definition of Fuel and Lubricant Consumption Rates and Production of Tractor Units As Part of John Deere Tractors
Authors: Ivanov Andrey
Published: February 2020

Tractors are mainly applied in agriculture. The share of import in the structure of tractor machinery market is constantly growing. One of the information sources for the optimization of the machine and tractor fleet and the development of standards to satisfy the needs of typical farms in tractors and agricultural machines for crop production are the performance standards of machinery and fuel consumption. The recommended norms of fuel production and consumption imply the rational use of shift time, optimal composition of machine-tractor units and effective operation modes of tractors and self-travelling agricultural machines. In recent years, many tractors and agricultural machines of foreign companies, including John Deere, are working in the fields of Trans-Urals, Siberia and Russia as a whole. The standards of production and consumption of fuels and lubricants for these agro-climatic conditions are not available for all machine-tractor units. Therefore, it is becoming ever more relevant for agricultural producers to develop such. The studies to establish fuel consumption standards and performance rates of machine-tractor units as part of John Deere tractors were carried out in the fields of agricultural enterprises of the Tyumen Region. The paper presents the results of the study. For example, the productivity of a tractor for a field located at a distance of 5–6 km and an average length of furrow of 1300 m can be in the range of 5.8–6.0 ha/h. Taking into account natural and climatic conditions and different physical and mechanical composition of soil, as well as configuration of fields and length of furrows during processing, the data on the consumption of basic lubricants were obtained. Recommendations on the use of consumption rates for fuels and lubricants of modern tractors in various technological operations in agriculture will greatly facilitate planning and calculation of operating costs of machine-tractor units. The paper considers recommendations on the use of correction factors to the nominal range of fuel consumption depending on soil type for John Deere tractors of the 9th series on the example of disk tillage. Software for economic evaluation of agricultural machinery as part of agricultural technology was developed.

Published: February 2020

The methods of mathematical description of evaporation processes from light soils of the arid zone of Russia are discussed. The focus is on the evaporation of moisture from the aeration zone. The analysis of theoretical work in this area and the results of their practical implementation are presented. Mathematical models of evaporation are divided into two types: physical and mathematical, taking into account the interaction of moisture with the soil frame and phenomenological, based on balance relations with the use of ordinary differential equations. The analysis of the actual material on evaporation from light soils of the Privolzhskiy sands was carried out in the light of the theory of evaporation from the capillaries surface in the pore space, taking into account the diffusion and film movements of moisture. A semi-empirical model of moisture movement in the upper soil layers in the form of analytical formulas relating the evaporation rate to the physical state of the soil water was used to estimate the water loss during evaporation. Good agreement was obtained between the theoretical provisions on the capillary movement of moisture and the data on evaporation from the sandy soils of the steppe zone of Russia. Approximation of data on the precipitation falling dynamics during the year by semi-empirical dependencies in the form of analytical formulas determines their practical use in the work of agricultural producers.

In conditions of market reforming in all development directions in Smolensk region, there are changes concerning the conditions, rules and principles of branches functioning in social and economic development of the region and its government. The main focus is on the development of only two industries working for export – electricity production and mining industry. The region is located in Non-Black Earth Region and requires investment for the development of its agricultural sector. Therefore, it was decided to eliminate the sphere of agricultural sector, which in pre-perestroika period provided the domestic demand of the country population in pre-perestroika period. Agricultural sector also provided Far East and Polar regions. However, nowadays agricultural production is aimed only at meeting domestic regional demand. Even after the reforms, agricultural sector and its basic part farming continues to be a small island of real business working for domestic demand. It is a backbone component for the economy of Smolensk region, a source of labor market and force application of region rural population. It ensures its food and economic security and has a high potential for rural development. However, at present its position is in a state of crisis, which is associated with low procurement prices for perishable products, the elimination of a processing system and purchase of agricultural raw materials, seed stock, breeding farm, lack of own production of feed additives and animal feed; care of qualified personnel and specialists from the industry and deterioration of the social base (elimination of schools, settlements, hospitals and medical assistants, culture establishments). At the same time, the tasks are set to ensure food security in the context of sanctions, which leads to a noticeable revival of the industry. There are new concepts in industry regulation at the regional level, transformations in management methodology and interaction mechanism for all levels from modernization to processing of end products in accordance with the requirements of the country’s development.

One of the most important indicators of the quality of life is environmentally friendly nutrition implying the use and rational combination of eco-friendly raw materials contained in recipes of new generation products, thus guaranteeing full supply of food and biologically active agents to all vital systems of an organism. The development of the society fosters the increasing interdependence and interconditionality of processes within the “nature-person-society” system. The current environmental situation brought the problem of environmental culture and its role in the optimization of socionatural interaction to the foreground. The paper presents the materials of theoretical justification of conceptual relations between the quality of life and eco-friendly nutrition; it describes pilot studies of safety indicators, polysaccharide composition of aromatic plants for their use in the production of functional food to enrich the composition with protective components. It is established that the studied aromatic plants (AP) growing in environmentally friendly territories of the Republic of North Ossetia-Alania are characterized by low weight ratio of toxic substances (below admissible hygienic standards), high content of dietary fibers (DF). The sorption capacity of AP powders in relation to lead is studied. All studied powders of AP modification products are characterized by high sorption capacity. The technologies of flour food with addition of AP powders are developed. It is revealed that in comparison with control samples certain flour food products almost twice reduce the lead content in the blood of laboratory infant rats.

The paper studies the influence of systematic application recommended and estimated mineral (N69P63K45 and N141P68K60) and organomineral (manure 8 t/ha + N44P42K24and manure 15 t/ha + N87P36K7) fertilizer systems within grain-grass-hoe crop rotation on density, porosity, structural condition of soil, water stability of structural units, water permeability, change of humus content and basic nutrition elements in rainfed conditions and at irrigation in comparison with their initial content and with indicators in control option – without fertilizers and irrigation throughout long-term field experiment on ordinary carbonate chernozem in a steppe zone of the Central Ciscaucasia. It is defined that over 68 years of experiments the content of total nitrogen, phosphorus, potassium and reaction of soil solution did not change. The maximum losses of humus and available forms of nutritious elements occurred in options without fertilizers in rainfed and irrigated conditions, bulk density of soil increased, porosity and water permeability decreased. The use of fertilizers improved agrophysical and water properties of soil: its density decreased, porosity, structure index, water stability, water permeability and hygroscopicity increased. The introduction of estimated organomineral fertilizer system to the scheme of experiment since 1986 restored the humus content in soil to the reference value and ensured its positive balance (+2.6 t/ha).

Published: February 2020

In the Republic of Kalmykia, the horse breeding segment is reaching up to 6 % of the whole agricultural industry. The number of horses has a tendency to increase. This is determined by the low cost, as well as by environmental friendliness of keeping horses, and horses’ adaptability to harsh conditions. There are four breeding plants on the territory of Kalmykia, which are actively involved in Kalmyk horses breed rearing. Recently a distinct meat-type was isolated within the Kalmyk breed, which was named “Tselinny” meat-type (further Tselinny). The goal of the presented paper is to compare purebred horses with a pool of horses belonging to newly isolated type Tselinny. Genotype of both populations consists of 14 and 15 alleles, as 84.4 % and 78.8 % of horses have these alleles (purebred and Tselinny type respectively). Animal of Tselinny meat-type do not have 16 and 17 alleles, while more than 10 % of purebred horses of the Kalmyk breed have these two alleles in their genotype. The difference in genotype is confirmed by the difference in phenotype: these are differences in size and meat productivity of horses. Both stallions and mares of Tsenilly meat type are bigger and have higher weight. When we come to the meat productivity, the weight of the meat from young animals of Tselinny type was by 21 % (45 kg) higher. Horses belonging to the Tselinny type differ from purebred animals of Kalmyk breed both in genotype and phenotype. At the same time, exemplar of both groups keep features of Kalmyk horse breed. It is important to develop different types within the breed, based on the intended goal of breeding.
Exteriority of Holstein Cattle of Various Origins in the Conditions of the Tyumen Region
Authors: Svyazhenina Marina
Published: February 2020

The modern production of animal products depends largely on the quality of animals. Dairy farming is most often based on the use of Holstein cows as one of the most adapted to industrial conditions[1]. The Tyumen Oblast has been importing the cattle of this breed since 2006, and it was imported from different European countries, as well as was obtained as a result of the absorption crossbreeding of cows of the domestic black-motley breed [2–4]. Since the productivity of animals to a large extent depends not only on the origin, but also on the external qualities of animals, a study of the exteriors of the first exteriors of the Korovogolshtin breed was carried out. In the course of the study, it was found that both the origin and the ”farm” factor were influenced by the exterior quality of the animals. Moreover, the influence of the ”farm” factor was greater than the origin of cows. The cows of their own breeding, obtained as a result of absorption crossbreeding, did not differ significantly from the imported cows by the majority of external indicators. This allows us to conclude that the imports may be replaced by our own reproduction, including the use of absorption crossbreeding of black and motley and Holstein cattle.

In intensive technologies of cultivation of potatoes, the need for trace elements is increasing. The concentration of trace elements in plants is very small, but the importance of these elements in biochemical processes is difficult to overestimate. The deficiency of trace elements is the root cause of many functional disorders. Trace elements in plants are part of enzymes, stimulate and accelerate plant development, increase resistance to adverse environmental conditions, etc. Also, with their shortage, crop productivity decreases. The use of natural minerals, such as glauconite, containing trace elements, allows improving comprehensive nutrition and increase productivity. Getting early production of high quality potatoes in the summer is important and relevant in the modern world. The use of glauconite in the conditions of the Moscow region, along with fertilizers and irrigation, allows obtaining high-quality products and increasing productivity by 6.3... 29.0%.

Chickpea is a cheap source of nutrients and does not require special soil conditions of growth. In addition, the properties of the symbiotic relationship of nitrogen-containing bacteria in its root system make it a valuable crop for agriculture. Due to its droughtresistant properties, it is one of the most dynamically developing cultures in export potential, which allows producers making profitable trading operations in foreign food markets and improving their financial condition. The climatic conditions of the Russian Federation make it possible to grow chickpeas and produce its seeds. The cultivated areas of chickpea in Russia in 2018, according to Russian Statistic Agency, amounted to 851.2 thousand hectares. Over the year, they increased by 71.6 %, from 2013 – by 26.5 %. Volgograd region in the all-Russian chickpea field occupies 22.5 % after the Saratov region, on yield it occupies the seventh position after the Stavropol Territory – 7.7 c/ha. Chickpea is a valuable crop, the cultivation of which will make it possible to obtain grain beans that are valuable for human food and to engage Russian agricultural producers in export operations. However, weed vegetation reduces the efficiency of chickpea production. The article describes a method of dealing with weed vegetation in chickpea crops in dry conditions. This will allow the use of tank mixtures of herbicides, which are cheaper in cost and effective in combating weeds in chickpea crops. Using this method, it is possible to get a crop without spending extra funds and achieve a profitability of 15 and 25.6 %.

The article the results of investigation on obtaining of surface-active substance -SAS on the waste cotton oil for drilling of wells and intensification of the flotation process are presented. The main component of new SAS are waste, cotton oil refinery and chemical plants. SAS have hudrophobization (waterproof) action on easy-swelling rocks (clays, argellites, alevrolits). Direct water emulsions obtained from reagents have low viscosity, high stability and low filtration index. There reagents have influence at drilling tools (that is they increase the life of drilling bits and diamond bits) [1, 2]. The study flotation enrichments of copper-molybdic ore is revealed characteristic foam-former and collector surface-active substances (NA-1) and is simulation one oily provided creation without minerals fields extraction of gold and color metals has been determined. Optimal conditions of the syntheses: ratio of main components, time of reaction, temperature and concentration have been determined. The comparison of new SAS with other foreing analogies was carried out. The main colloidal-chemical characteristic of synthesized SAS: surface activity, adsorption, viscosity, concentration of micelle- formation have been determined. Technology of obtain of anion surfaceactive substances from local organic raw material was elaborated, which by qualitative characteristics is a substitute of the import reagent collector and foam-former [4, 5]. Dependence on obtained product from the temperature of the process, time of reactions, ratio of initial components optimal concentration of NaOH was investigated. The foam forming ability of the new reagents in comparison with standard reagent T-92 was determined and it was shown that by best ability of forms destruction the methyl syloxane’s liquid and mineral oil have possessed.The intensifications of the process of flotation’s enrichment of copper-molybdic ore with using new obtain reagent NA-1 was offered.

The State Agrarian University of the Northern Trans-Urals continues to breed spring wheat. Two varieties of Tyumen Jubilee and Tyumenochka have been created with the use of various source materials, including sources to the main cultural diseases in the region. Tyumenskaya variety has passed the State Variety Testing and is included in the Register of breeding achievements in 10 regions. The second variety is in the State Variety Trial. Research is continuing on both varieties to develop seed varieties. The results of influence of different levels of mineral nutrition on yield and quality of seeds of wheat varieties are analyzed in this report. It is established that in the northern forest-steppe zone of the Tyumen region on the natural fertility of leached black soil the average seed yield for three years was for the variety Tyumenskaya jubilee 2.48 t/ha, for Tyumenochka – 2.08 t/ha. In the variant with application of mineral fertilizers to the planned yield of 4 t/ha, the first grade seed was obtained 3.29 t/ha, the second – 2.91. The additions to the control variant were 0.81 and 0.83 t/ha. When applying mineral fertilizers to the yield of 5 and 6 t/ha, the additions remained at the level of the previous version, except for the Tyumenochka variety in the last version. The yield of seeds from the total yield in the control variant was 75.5 % for the variety Tyumenskaya jubilee and 71.7 % for Tyumenochka. In the variant with NPK by 4 t/ha the yield of seeds increased by 4.2 % in the first grade and by 4.5 % in the second grade. Protein content in the seeds of wheat varieties on the natural soil fertility was 13.6 and 12.3 %, respectively. The maximum content of 16.0 and 14.8 % is noted in the variant with fertilizers for the planned yield of 4 t/ha. In the same variant the highest germination energy (82.3, 80.1 %) and germination of seeds (96.9 and 95.5 %) are higher than the control variant by 20.7, 15.6 and 1.8 %; 2.5 % accordingly. The main part of the seeds (71.0 and 68.1 %) of the studied wheat varieties in the mentioned variant grew with 5–6 germ roots that is 19.3 and 13.2 % higher than the control. The variant with fertilizers for the planned yield of 4 t/ha was more economically advantageous, the level of profitability of the variety Tyumenskaya jubilee was 49 %, and Tyumenochka 44 %.
Using genetic Potential of Teosinte from Collection of N.I.Vavilov Research Institute of Plant Industry to Expand Polymorphism of Prolific Maize (Zea mays L.)

A threat of genetic erosion of maize stimulate search for new sources to extend its polymorphism. Teosinte (Zea mays ssp. mexicana), being wild relative of maize, is easily intercrossed with maize and is characterized with a large potential of variability with respect to economically viable attributes, among them being prolific that is having more than one ear. Results are given of long-term selection of maize lines for the attribute of being prolific among the progeny of a hybrid between teosinte (int-350969) and maize. Selection was conducted against the background of soil preparation ideal for maize in a number of attributes that are congruent with prolificacy and synchronous blooming of all or at least majority of ears on a stalk. A wide diversity in the prolificacy of maize was obtained, with the prolificacy coefficient of up to kpr = 3.3 with a complicated mode of inheritance in hybrid progeny. Results of topcrossing with a single-ear sterile tester showed a specific reaction of the lines, provisionally dividing them into 4 groups by the nature of manifestation of the prolificacy in the hybrid progeny. It has been established that the prolific lines, which in hybridization with the single-ear tester are capable of forming more than one ear in the hybrid plant are of higher selective value. At that, it is important to take into account simultaneity of blooming of all the ears at a male plant. Observation of this principle leads to preservation of structure and evenness of ears in upper and lower layer, thus providing their productivity independent of layer on the stalk. Valuable prolific lines have been established for creation of prolific maize hybrids.
