The article is devoted to the study of the influence of sowing methods, seeding rate and herbicide on the development, yield and photosynthetic activity of chickpea sowing – one of the most controversial issues in chickpea agricultural technology. The influence of sowing methods and seeding rates on the photosynthetic activity of plants has been studied. The selection of effective measures to control chickpea weeds is also part of our research. One of the most significant issues for obtaining high yields of chickpea is the correct sowing method, seeding rate and the use of herbicides. The studies were carried out in 2017–2018. on the experimental field of the North Caucasus Research Institute of Mining and Piedmont Agriculture of the All-Russian Scientific Center of the Russian Academy of Sciences on leached chernozems: arable layer pH salt. 5.8–6, humus content 5.8%, easily hydrolyzable nitrogen – 80 mg/kg, available phosphorus – 118 mg/kg, exchangeable potassium – 120 mg/kg, molybdenum – 0.25 mg/kg, boron – 0,5 mg/kg of soil. In field experiments, the seeding rates, the method of seeding and the effect of herbicides were studied. The aim of the research was: to develop agricultural practices that ensure the collection of grain products and vegetable protein in the foothill zone of RNO-Alania. According to the results of the studies, in the conditions of the foothill zone of the Republic of North Ossetia – Alania, according to the complex of indicators of plant activity, variants were distinguished when applying the herbicide with seeding rates of 0.8 and 1.0 million viable seeds per hectare with a wide-row sowing method and with seeding rates 0.6–0.8 million germinable seeds per hectare with the drill method. Against a herbicide-free background, the best options were with a seeding rate of 1.0 million viable seeds per hectare, both with wide-row and with a row sowing method.

In a long-term places, located on the experimental fields of Siberian Research Institute of Agriculture (Omsk), the schemes of field crop rotations were modernized by introducing oil crops (rapeseed, soybean) into rotation and replacing the repeated wheat crops with barley and oats. Accounting of grain crops productivity and accompanying observations were carried out in three field rotations of different lengths of rotation (four- and five-field) and on permanent sowing. The repetition of the experiments is fourfold. The system of agrotechnical measures recommended for the zone of the forest-steppe of Western Siberia was applied. The study of predecessors in the cultivation of crops for various purposes was carried out in field experiments using conventional methods. The humus content for rotation in the soil layer of 0-40 cm increased by 0.19% in the crop rotation “rapeseed - wheat spring wheat - barley - soybean - spring wheat”. The largest accumulation of humus (0.83%) was in the rotation “soybean - spring wheat - barley – oats”. During the years of research wheat productivity varied from 0.82 to 2.22 tons per hectare. Wheat was the first crop in all its predecessors to form grains, on average, by 0.3-0.5 tons per hectare, than the second crop. The yield of soybeans in the crop rotation was 1.23-1.78 tons per hectare. The productivity of rapeseed was low, its productivity over the years was 1.31 tons per hectare. Grain-fodder crops (barley, oats) averaged 0.4-0.6 tons per hectare, higher than the spring wheat productivity in the alternating rotation. The maximum yield of grain from a hectare of arable land was noted in the crop-steam rotation and amounted to 1.7 tons. An increase in the yield of feed-protein units was observed in crop rotations saturated with oil crops (rapeseed and soybean) and amounted to 3.4-4.0 tons per hectare. The economic calculation showed that the cultivation of field crops in the rotational crop rotation of “soybean - wheat - barley – oats” increased profitability by 44%, net income - by half, in comparison with the control variant. The obtained materials can be used to develop schemes of field crop rotations for the zone of the forest-steppe of Western Siberia.

Background. An extremely important task today is to develop new hulless barley cultivars, capable of yielding large and high-quality grain harvests, and introduce them into agricultural production. Objective. The purpose was to study three hulless barley cultivars ‘Omsky golozerny 2’, ‘Omsky golozerny 4’ and ‘Maysky’, developed at Omsk Agrarian Scientific Center, in order to describe their agrobiological characteristics.Materials and methods.The experimental part of the work was carried out in 2015–2017 on the experimental fields of Omsk ASC in the southern forest steppe (third crop rotation after the wheat predecessor; fourth crop after fallow). There were 4 replications on the plot of 10 m2. The seeding rate was 4 million viable seeds per 1 ha. Agricultural practice used in the experiments was conventional for West Siberia. Parameters of stability and plasticity were calculated according to Eberhart and Russell, Wricke; adaptability, according to Zhivotkov; homeostasis, according to Khangildin; stress tolerance and compensatory ability, according to Rossielle and Hemblin.Results. Many years of breeding work at Omsk ASC resulted in the development of three hulless barley cultivars: ‘Omsky golozerny 2’ (listed in the State Register of the Russian Federation for regions 9, 10 and 11), ‘Omsky golozerny 4’ (submitted for the State Crop Variety Trials in 2017), and ‘Maysky’ (not included in the State Register). The new hulless barley cultivar ‘Omsky golozerny 4’, considering its higher productivity (+1.36 g to the reference in 1000 grain weight, and +0.73 t/ha to cv. ‘Maysky’), in the yield of nutrients per area unit equaled the reference ‘Omsky golozerny 2’, but exceeded ‘Maysky’ (+47.2 kg/ha of protein, +390 kg/ha of starch, and +42.4 kg/ha of crude fat). ‘Omsky golozerny 4’ was also characterized by stability (stability = 4.8), increased compensatory ability (3.29) and adaptability (103%). There was an increase in productivity with improved growing conditions (ecological plasticity = 1.25). ‘Maysky’ had higher stress tolerance (–1.35), while the reference ‘Omsky golozerny 2’ showed increased homeostasis (0.118). Thus, ‘Omsky golozerny 4’ exceeded the previous two cultivars in adaptability and stability.

Abstract. The authors present the results of the use of herbicides on winter wheat crops in the steppe zone of North Ossetia-Alania. The purpose of the work is to study the effectiveness of the use of herbicides in winter wheat crops. The object of research is two varieties of winter wheat – Trio and Utrish, which differ in maturity, susceptibility to leaf-stem pathogens. The novelty lies in the fact that for the first time in the steppe zone of the Mozdok region, in the research and production department of the North Caucasus Research Institute of Mining and Piedmont Agriculture of the All-Russian Scientific Center of the Russian Academy of Sciences, the effectiveness of the use of herbicides in winter wheat crops was studied, an economic assessment of the studied agricultural techniques was given. Methods. The counts and observations were carried out according to generally accepted methods described in the “Educational-methodical guide for conducting research in agronomy”. Results. As a result of the use of herbicides and their tank mixture, it contributed to a significant reduction in the number of weeds (the percentage of death in the bumping phase varied between 55.9–81.1 % compared to the control). The removal of mineral nutrition elements by weeds was: nitrogen – 72.6 kg/ha, phosphorus – 14.4 kg/ha, potassium-52.4 kg/ha. Herbicides had a positive effect on photosynthetic activity. The leaf area during its maximum development (earing phase) according to the studied variants increased by 12.7–16.4 %, and the photosynthetic potential – by 13.7–17.8 %. The PPF for the studied options (the average value for the growing season) increased by 0.34–0.51 g/m2 per day. The studied drugs contributed to a significant increase in productivity. The largest increase was obtained according to the option: Grench (5 g/ha) + Luvaram (800 ml / ha) – 2.39–2.60 t/ha. The profitability level in the control (without herbicides) was at the level of 25.7 % (grade Trio), and according to the studied options ranged from 148.7 % (Luvarum 1600 ml / ha) to 169.2 % (Grench 5 g/ha + Luvaram 800 ml/ha).

The research was carried out in order to determine the optimal time for sowing winter wheat according to various predecessors in the changing climate of Volga forest-steppe. The work was carried out in 2013–2019 in Ulyanovsk region on heavy loamy leached chernozem using conventional techniques. The experimental scheme provided for the study of two predecessors (peas and pure fallow) of winter soft wheat of Marafon variety, sown at 6 sowing dates with an interval of 10 days (from August 20 to October 10). The seeding rate for pure fallow is 5.0 million viable seeds per hectare, for peas - 5.5 million viable seeds per hectare. Average annual air temperature for 1961–2018 increased by 1.8°С. Its most significant increase was noted in the last twenty-five year period of time in the winter months. The increase in the frequency of extremely warm winters and temperature variability in the winter period significantly changed the conditions for overwintering winter crops. The danger of the development of wintering weeds, damping diseases, and soaking of winter crops has increased, and the conditions for overwintering pests have improved. It is possible to mitigate the danger of the natural and climatic vulnerability of crops during the wintering period by observing the optimal sowing dates, which should be postponed to a later period (7 ... 12 days), compared with the previously recommended ones. The optimal sowing period for winter wheat in Ulyanovsk region is from August 30 to September 10. Earlier crops are more intensively affected by diseases (powdery mildew and brown rust), and later crops, which have left in the winter in the germination phase, form a low density, form a small ear and provide low productivity or completely die

Biological farming throughout the world is becoming a necessity for the production of safe products, and the preservation of fertility and biodiversity. In this direction, there is a significant interest of the scientific community in the perennial culture – cup plant. The cup plant has a wide range of uses in economic activities and due to its high resistance to diseases and pests, the long-term use of its plantations without replanting, and the accumulation of a significant mass of organic matter in the soil, it can be used to expand the species diversity of perennial grasses in the biological farming system. The aim of the study was to examine the influence of the seeding method and seeding rate on photosynthetic activity and dry matter productivity of the cup plant in the forest-steppe conditions of Western Siberia. It was found that with an ordinary method of sowing at a seeding rate of 4 million pcs/ha, the grass stand in the first cut had the highest rates of photosynthetic activity on average over the years of research: the leaf area was 14.8 m2 /m2 , the photosynthetic potential was 4.0 million m2 day/ha and the net productivity of photosynthesis was 2.0 g/m2 ⋅ day. In the second cut, the figures were 8.4 m2 /m2 , 1.9 million m2 day/ha and 2.8 g/m2 ⋅ day, respectively. The optimal density of herbage and active photosynthetic activity in the cup plant using this method of sowing contributed to a significant yield of dry matter of 12.6 t/ha with a high level of PAR absorption of 2.9%.

Field research conducted in three field experiments: 1) Right Bank Forest-Steppe of Ukraine (PC NULES “Agronomic Research Station,” v. Pshenychne Vasylkiv district, Kyiv region); 2) zone of sufficient moisture in Austria (Wald und Myulfirtel, p. Kauttsen, North of Lower Austria); zone of unstable moisture of Austria (Nordostlyhes Flah und Hyuhelland, v. Leopoldsdorf, East of Lower Austria). Field multifactor experiments was laid on the same pattern in each of the farms in 2012 – 2014: variety (factor A); rate of nitrogen nutrition (factor B), seeding rate (C factor). Were chosen six varieties, genetically different by baking quality and origin: strong varieties – Lybid, Joseph, Midas, Capo; valuable – Balaton, Polis’ka90. Nitrogen was applicated by next four graduation(with introduction during vegetation under phases: autumn tillering – ВВСН 10-21 / spring tillering – ВВСН 25-29 / booting – ВВСН 30-31 Earing – ВВСН 51- 59): D1 – control without nitrogen; D2 – 120 kg / ha a.i .(0/60/60/0); D3 – 180 (0/60/60/60); D4 – 150 kg / ha a.i. (30/60/60/0). The article presents experimental data from two options of nitrogen supply – con­ trol without nitrogen (D1) and the maximum standards for nitrogen fertilization in three applying – 180 (0/60/60/60) kg / ha a.i. (D3). Seeding rate: 3,0; 4.0 and 5.0 million germinated seeds per hectare. Phosphorus and potassium – 90 kg a. i., applied as background during primary tillage. Preceded of winter wheat – winter rape. In average during years of research the highest yield made – 9.07 tonnes / ha in conditions of East Austria (p. Leopoldsdorf), North Austria (p. Kauttsen) – 9,42 and Right Bank Forest-Steppe of Ukraine (v. Psenychne) – 8.65 t / ha with application of nitrogen (D3). In control variant was observed significant fluctuations in yield – from 3.51 (v. Psenychne) to 5.21 t / ha (v. Leopoldsdorf). There is significant dependence between wheat yields with weather conditions of the year. Find out the optimum seeding grades for conditions of Ukraine and Austria. Estimation of the ecological plas­ ticity and stability of winter wheat varieties were studied. Determinants of wheat quality formation were acertained. The highest mass fraction of protein was achieved by growing strong varieties and introduction of 180 kg / ha N (D3) in all experiments, in average of the study years, in section of soil and climatic conditions (untypical droughty 2012 for v. Leopoldsdorf was excluded). The highest protein content in conditions of Right-Bank Forrest-Steppe of Ukraine obtained at level 15.8%; East Austria – 15.4% and North Austria – 15.0%. Control variant, without nitrogen, allowed to evaluate the potential of soil and variety in the studied environmental conditions – the aver­ age protein content in grain in conditions of Austria reached 12.2% (v. Leopoldsdorf) and 12.4% (v. Kauttsen), of Ukraine – 11.6% (v. Psenychne).
