Authors: Aminova E V , Mushinskiy A A 
Published: November 2019

Abstract
At present, rapid development of nanotechnology requires assessment of their effects on plants, interaction with plant cells and concentration dependence. The degree of toxicity of nanocompounds affecting plants depends on physical properties of nanoparticles (dimension, shape, catalytic activity, concentration). The research objects were Tarasov potato tubers treated in Fe° (90-110 Nm) and Cu° (50-110 Nm) NPs at four concentrations with a geometric progression (0,0125; 0,025; 0.05 and 0.1 M). The aim of the research is to study the effect of iron and copper metals on the activity of Solánumtuberósum L. antioxidant protection of plants. The Fe0 NPs caused oxidative stress and decreased the content of MD (1.3 - 26.7%) and phenolic compounds with a simultaneous increase in peroxidase. After exposure to Cu0 nanoparticles, there was a redox imbalance in the roots and sprouts which manifested itself as a decrease in CAT (7.4-36.7%) and FS (19.1 - 34.0%) activity with a sharp increase in the content of MD and an increase in peroxidase activity.

Abstract
We studied the effect of metal nanoparticles (Fe, Mo and SiO2, and also Fe and Mo together) at concentration of 10, 25 and 50 mg/kg dry weight of soil on the morphological and biochemical parameters of soft wheat. (Triticum vulgare Vill). We found that morphometric parameters of test samples were generally superior to control samples. In course of assessing the viability of plant cells, we recorded that experimental groups had viability values of at least 90%. Thus, it allowed us to conclude that the concentrations of nanoparticles used by us did not have a toxic effect on the viability of the roots. When evaluating the enzymatic antioxidant system of plants and the degree of lipid peroxidation, we noted the absence of oxidative stress, while increasing the protective potential of plants. Thus, our studies are the basis for studying the possibility of using nanoparticles in agriculture for intensifying plant growth and increasing their yield.

Published: November 2019

Abstract
We studied the effect of chromium (III) oxide nanoparticles of various dosages on the elemental status of the organism. Experimental studies were conducted using 150 heads of broiler chickens "Arbor Aykres". The control groups of birds received the main ration, and the experimental groups received chromium (III) oxide nanoparticles in doses of 50; 100; 200 and 400 μg/kg feed. It was noted that with the introduction of chromium (III) oxide nanoparticles into the diet, an increase in the content of Ca, Zn, Cr, Co in dosages of 100-200 μg/kg occurs. The introduction of chromium nanoparticles into the diet of broiler chickens in dosages of 100–200 μg/kg stimulates exchange of chemical elements, increases Co, Cr, Ca, Zn and depresses Cd, Pb exchange. Depending on the concentration of chromium nanoparticles in the diet, the most active phase is the range of 100–200 μg/kg, at which the active metabolism of the main chemical elements occurs.

Abstract
Zinc ferrite nanoparticles (ZnFe2O4) are being increasingly investigated due to their wide biological application. In this study, zinc ferrite nanoparticles were synthesized by green method using Petroselinum crispum. The synthesized magnetic nanoparticles were characterized using SEM technique. The biological activity of the preparations produced was studied on a test plant of wheat Triticum vulgare L. Wheat plants were grown in hydroponic medium with the addition of ZnFe2O4 nanoparticles in concentrations ranging from 10−5 to 10−1 M. On the third day, the germination rate of wheat seeds was calculated. The results showed that powders of acidic nature (pH=2) significantly reduced seed germination relative to the intact samples at concentrations of 10−3 and 10−4 M (by 100 and 47% relative to the control, respectively). ZnFe2O4 synthesized in alkaline medium reduced the germination rate to a lesser extent, and at similar concentrations – to 7.3 and 22.8%. Moreover, at the minimal concentration of 10−5 M, there was a slight increase in germination up to 19.3%. Cell viability of seedling roots was evaluated by transformation of the water-soluble tetrazolium salt to formazan (WST-test). Higher cell viability was observed after exposure to zinc ferrite produced in alkaline medium as compared to preparations produced in acidic medium. Particles synthesized in acidic medium at the concentration ranging from 10−1 to 10−5 M decreased cell viability to 77% relative to the control samples, and the preparation produced in alkaline medium under similar conditions reduced the rate only at maximum concentrations of 10−1 and 10−2 M to 53%. In the case of treatment of 10−5 M ZnFe2O4 of alkaline nature, cell viability was observed to grow up to 23% relative to the control samples.

Abstract
The paper presents the results of research on feed additives based on wheat bran including highly dispersed metal powders (Ca, Cu, Zn and Fe) in various combinations subjected to extrusion processing. Physical properties (porosity) of the experimental feed substrates were assessed by the method of determining the porosity of acetone in accordance with GOST 6217. To determine feed digestibility and bioavailability of elements in vitro, an “artificial rumen” was used. The elemental composition of feed samples was studied by atomic emission spectrometry with an inductively coupled plasma (AES-ICP). Finely dispersed powder of Ca (up to 10 μm), Cu, Zn, Fe (9-10 μm) was studied. Digestibility of dry matter of feed substrates was dependent on their porosity. Extrusion of bran products increased dry matter digestibility by 6.8%, and addition of fine powder increased it by 14% (P≤0.05) in vitro conditions. An increase in bioavailability of minerals after extrusion of Cu, Zn and Fe by 19.3, 6.3 and 23.1% (P≤0.05), and after addition of highly dispersed metals by 2.98 (P≤0.05), 21.6 and 7.3% ( P≤0.05) was identified

Published: November 2019

Abstract
Over the past decade, nanotechnology has led to the need for rigorous research on ultrafine nanomaterials, which increase productivity and quality of agricultural products. However, most studies are extremely controversial regarding the effect of nanomaterials on the seed germination rate, the growth of the roots and the aerial parts of plants, or it is difficult to compare both in doses and dimensions of nanoparticles, and in types of plants. In the experiment, nanoparticles of Fe (90-110 nm), Cu (50-110 nm) and Mo (100-120 nm) in 4 concentrations with a geometric progression were used. Germination energy and germination were determined according to GOST 12038-84, the content of photosynthetic pigments according to the method of N. D. Smashevsky (2011), phytotoxicity according to the method of Kazeev K. (2003). Thus, the data obtained indicate that the treatment of Solánum tuberósum L. tubers with iron nanoparticles stimulated the growth of sprout length (55.1% and 21.4%), roots (34.4% and 12.5%) and the content of chlorophyll a (57 - 98%) relative to the control at a concentration of 0.0125 … 0.025 M. At the same time, the nanoparticles of copper and molybdenum by the significance of their effects on plants turned out to be ineffective.

Published: November 2019

Abstract
Changes in the cattle’ microbiocenosis of the rumen directly impacted the animals’ productivity. And the main role here is played by the feeding type, the animal’s diet, with a predominance of certain components in different periods of cows housing, which create the necessary conditions for the existence and activity of symbiotic microflora, as well as the development of associated pathologies. Earlier detection of these errors will help to avoid many abnormalities of metabolic processes in the body and prevent the decline in the animals’ productive qualities. That is why it is relevant to study the effect of ultrafine particles on the composition of cattle’ microbiota of rumen. In this article, we analyzed the cattle’ bacterial microbiocenosis in response to the introduction of ultrafine particles (FeCo and silicon oxide SiO2 alloy) into their diet. It is revealed that these ultrafine particles do not have a significant qualitative change in cattle’ microflora of the rumen, but shift the bacterial communities balance towards those microorganisms that improve the food digestibility, which allows them to be recommended as food additives to improve the farm animals productivity.

Abstract
The purpose of this work is to prove and develop the principal methods of increasing beef production on the basis of application of pasturing technology with subsequent intensive feeding of different breeds of bulls for two months and to calculate the relative economic efficiency of both cycles of summer keeping of the young cattle on the mountain pastures and in the conditions of the complex. During the whole time of grazing the bulls had an access to the water source. As well, they were given feeding concentrates in bad weather, when the animals grazed badly and did not eat till full. Salt in wooden feeders constantly lay in the cattle camp. The cattle received chalk together with the salt. Upon returning from the mountain pastures, those bulls of both breeds which were not intended for intensive feeding have been implemented at the meat in the amount of 40 heads and their average live weight was: the Kalmyk – 416 kg; brown Swiss Breed – 401 kg. The bulls in the amount of 42 heads that might not be sold for slaughtering were put on intensive feeding for two months in the conditions of the complex. It is established that the use of mountain-pasture keeping of young cattle is a very effective activity in cattle breeding. Carrying out the final intensive feeding in a complex or a farm for 2 months after not intensive feeding on mountain pastures is an economically - effective measure.

Abstract
The improvement of the quality of eggs, decrease of developmental anomalies, increase of progeny survival rate are urgent problems of industrial fish breeding. We used biologically active agents – vitamins and adaptogens to solve the above problems. Adaptogen trekrezan (ethanolammonium salt of 2-methylphenoxyacetic acid) – a synthetic analog of ginseng – was applied in fish breeding. It does not demonstrate any gonadotoxic, embryotoxic, mutagenic, teratogenic, carcinogenic and allergenic action and is not accumulated in the organism. The agent has high immunotropic activity, stimulates cellular and humoral immune response, phagocytosis, demonstrates interferon inducer activity. We also used vitamin B1 – thiamine. The need for it is the highest in early ontogenesis. It is required for normal functioning of nervous, digestive and cardiovascular systems, hematopoietic system and is considered essential. The study of the influence of thiamine and trekrezan on egg fertilization rate showed that under the influence of these biologically active agents both individually and in a complex the fertilization increased by at least 14%. The study of the influence of thiamine and adaptogen on larvae hatching showed that they can increase the hatching by more than 20%. The study of the influence of thiamine and trekrezan on the level of developmental anomalies of African sharptooth catfish larvae showed that both components reduce this indicator. With the use of thiamine and trekrezan the level of developmental anomalies decreased in all groups by more than 10%. The study was supported by the Russian Foundation for Basic Research, grant No. 18-016-000127.
Control of airborne infections of wheat
Authors: Kekalo A Yu , Zargaryan N Yu , Filippov A S , Nemchenko V V 
Published: November 2019

Abstract
Leaf-stem infections damage the wheat crop. Puccinia recondite and Blumeria graminis are especially harmful. There were outbreaks of septoriosis and pyrenophoresis (Stagonosopra nodorum, Pyrenophora tritici-repentis) and linear rust (Puccinia graminis). The lack of spring wheat crops and deterioration in the grain quality caused by epiphytoties is 25-50%. An effective method for controlling aerogenic infections is the use of fungicides. Studies on the effectiveness and feasibility of fungicidal protection of wheat against pathogens were carried out in Kurgan region. It is economically feasible to use Bacillus subtilis-based substances to prevent wheat infections. In case of a moderate wheat damage, it is recommended to use tank mixes (1/2 of systemic fungicide + hay-bacillus-based biofungicide). In case of mass development of leaf-stem infections, it is necessary to protect the crops using systemic fungicides if there is primary infection of a lower tier of leaves and weather conditions are favorable for pathogens. The use of fungicides preserved more than 30% of the wheat crops and improved the quality of grain. Profitability of chemical protection options increassed by 20-26 %.

Abstract
This article presents statistical parameters for the cultivation of oilseeds in Russia. Ryazan region is not among the regions that are traditional producers of vegetable oil, but recently oilseed production has been actively developing in the region. Gradually developing and processing oilseeds. In 2018, the area under oilseeds in Ryazan region was 121.1 thousand hectares (+ 25.7 thousand hectares by 2017). The prospects for the use of mustard in the region are noted. Currently, the production of mustard grain in Ryazan region has decreased from 18.6 to 13.1 thousand hectares, which indicates an underestimation of the significance of this crop. The study of multicomponent liquid fertilizers in the field confirmed their beneficial effect on the growth and development of white mustard. Foliar dressing according to the vegetation phases contributed to better preservation of plants, due to this, and obtaining the greatest yield of white mustard seed. The maximum number of seeds was obtained on variety Lucius - 13.9 dt/ha, with the effect of Azotovit + Phosphatovit + RauAktiv - 16.5 dt/ha. The effective action of Galleon herbicide on such weed families as Asteraceae, Labiatae, Solanaceae, some species of Polygonaceae and Chenopodiaceae was observed.

Government support for agriculture and evaluation of its effectiveness at the macro and micro level
Authors: Larionova N P 
Published: November 2019

Abstract
State support for agriculture is an important element in the regulation of the agroindustrial complex. The necessity for state support for agriculture arises from the characteristics of agricultural production that reinforce the non-competitiveness of the industry. The economic efficiency of agricultural production, the pace of its development, the level of food security, and the state of rural areas will depend on the efficiency of its use. Over the past decades, increased competition has been observed virtually throughout the world. One of the most important, in our opinion, factors affecting the competitiveness of agricultural products is the state policy in the field of regulation and support of agricultural producers. The paper studies the state support of agricultural production in Russia and the Tyumen region, analyzes the state support and evaluates the effectiveness of state aid at the macro and micro levels. The research methodology includes two parts. The first one studies the forms, types, methods and volumes of state support for agriculture. Due to a number of reasons, the mechanism of state support is undergoing continuous reform. The stages of the reform and the impact of changes on agriculture are considered. The second part is aimed at studying the existing methods for assessing the effectiveness of the use of budgetary funds at the regional level. The requirement of efficient use of budgetary funds is established by the Budget Code of the Russian Federation. The paper proposes to consider the control of the effectiveness of state support in two aspects: as the effectiveness of measures and as the effectiveness of the use of state support funds. The article summarizes the existing methods of evaluating the effectiveness of the use of budgetary funds. On the example of the materials of agricultural organizations of the Tyumen region the work assesses the effectiveness of using direct budget support, and formulates ways to improve state aid to the agricultural sector of the economy. The obtained results are the basis for making management decisions in the agro-industrial complex of the Tyumen region.
