For feed production in particular and animal husbandry in general an important aspect is the improvement of technologies for the cultivation of various forage crops. The purpose of the research was to optimize the technology of cultivation of hulless barley under the environments of the Southern forest-steppe of Western Siberia due to the timing of sowing, seeding rates and the use of chemical agents. The technology of cultivation of hulless barley of the Omsk hulless barley 2 variety on meadow-chernozem soil in the Southern forest-steppe of Western Siberia has been scientifi cally proved and practically confi rmed. The optimal values of the elements of technology such as sowing rate, sowing date and the level of chemicals and their impact on yield and grain quality of hulless barley. The dependence of each element of the technology on the infestation and water consumption of barley has been established. Among the used seeding rates, the grain yield was higher at 4,5 million/ha – 2,56 t/ha. Close result was at 5,5 million/ha – 2,54 t/ha, but taking into account the greater consumption of seeds this option loses. A decrease in seeding to 3,5 million/ha led to decrease in grain yield to 2,37 t/ha. The share of the seeding rate in the yield change was 6,2 %. The optimal yield of gross energy has been observed at the fi rst sowing period and the seeding rate 4,5 million/ha. The increment of gross energy as the diff erence between its output and the total energy consumption reached a maximum against the background of herbicides 32,363 MJ/ha. Here the energy coeffi cient was higher 4,62. Both in terms of bioenergy and economic effi ciency, the best option was to plant 4,5 million/ha against the background of the use of herbicides.

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.

A 3-year study was conducted to measure the effect of sowing time and seeding rate on the development and yield of wheat (Triticum aestivum L.) grown under high-yielding conditions in north-eastern Victoria. A range of wheat cultivars with different development responses, including 'winter' types, was used in 2 experiments in each season. High grain yields for dryland wheat were measured in the first 2 seasons (1985-86), and in 1985, near-optimal water use efficiencies (>18 kg/ha. mm effective rainfall) were obtained. In the third season (1987) grain yield was limited by adverse climatic conditions-in the me- and post-anthesis period. In each season, grain yield declined with delay in sowing time. In 1985 there was a loss of 200-250 kg grain/ha for each week's delay in sowing time. In 1987, yield loss with delayed sowing was 50-110 kg grain/ha. In each season, cultivars with late or midseason maturity development gave the highest mean yields, and the use of these maturity types allowed earlier sowing, in mid April. However, with late sowing of wheat there was a trend for early maturity types to give higher yields, and so the use of 2 wheat cultivars with distinct maturity development responses to climate is recommended. If only 1 wheat cultivar is to be used, then a late maturity type is recommended. Higher wheat yields were also obtained as spike density increased, as a result of higher seeding rates. Our data suggest that in the higher rainfall region of north-eastern Victoria, a spike density of about 500 spikes/m2 is required to optimise wheat yields.

The possibility of increasing the yield of fodder-grain crops in single-species agrocenoses to provide livestock with nutritious highquality feed was studied. The results of field and laboratory studies (2016–2018) on the cultivation of traditional (barley, oats, spring and winter rye) and uncommon fodder crops (triticale, corn) sown as single crops in the forest-steppe zone of Trans-Baikal Territory are presented. The objects of the research were the following recognized varieties of the crops under study: local winter rye Zhitkinskaya, spring rye Onokhoyskaya, oats Metis, barley Anna, triticale Ukro, corn hybrid Obsky 150 CB. The experiment was conducted on meadow chernozem mealy-carbonate soil (light loam by particle size distribution). Poaceous fodder crops were assessed in terms of their adaptability to growing conditions, yield and nutritional value of grain. Their economically valuable characteristics were shown. On average over the years of research, when cultivating traditional and uncommon poaceous crops for fodder grain in single-crop sowings, triticale and corn had an advantage. The grain yield in the experiment was 3.0-5.8 t/ha, collection of fodder units – 3.39-6.13 t/ha, digestible protein 287-494 kg/ha, gross energy – 34.7-60.5 GJ/ha, availability of digestible protein – 85–77 g per one feed unit. Traditional crops were inferior to uncommon crops in terms of grain yield by 0.5-3.3 t/ ha, (on average for the variants of the experiment), feed units – by 0.99-3.73 t/ha, digestible protein – by 85-292 kg/ha, gross energy – by 0.99–35.7 GJ/ha.

В Центральном Черноземье большая часть кормов производится на пашне. В связи с этим эффективность животноводства зависит от стабильного обеспечения животных качественными и недорогими кормами. Наиболее доступными кормами являются многолетние травы. Внедрение новых видов и сортов нетрадиционных кормовых трав с улучшенными хозяйственно полезными признаками является важным резервом для кормопроизводства. Межродовой гибрид фестулолиум ценная кормовая культура для полевого и лугового травосеяния, которую можно использовать на зелёный корм, сено, силос, сенаж, а также при создании культурных сенокосов и пастбищ. В связи с этим для более широкого внедрения в производство требуется научная разработка приёмов возделывания, обеспечивающих получение высоких и устойчивых урожаев семян. Важными элементами технологии возделывания фестулолиума на семена являются норма высева семян и способ посева. В представленных исследованиях, проведённых в 20062009 годах, изучены биологические особенности и семенная продуктивность при использовании разных норм высева и обычного и черезрядного способов посева. По результатам проведённых исследований можно отметить, что посев фестулолиума рядовым (15 см) или черезрядным (30 см) способами с нормой высева 6,0 кг/га позволяет сформировать разреженный слабополегающий травостой. Ассимиляционный аппарат фестулолиума наиболее продуктивно ассимилировал при обычном и черезрядном способах посева с нормами высева 6,0 и 9,0 кг/га, о чём свидетельствует максимальное значение фотосинтетического потенциала 10291090 тыс. м2сут/га. Чрезмерное загущение посевов (до 12,0 кг/га) отрицательно сказалось на элементах структуры урожая, привело к полеганию растений, уменьшению их продуктивности. Установлено, что максимальная семенная продуктивность фестулолиума получена в травостоях с нормой высева 6,0 кг/га и густотой стояния 130133 шт./м2: при рядовом способе посева урожай семян в среднем за 3 года составил 604,3 кг/га, а при черезрядном 652,3 кг/га. In the Central Non-Chernozem region the greatest part of forage comes from grasslands. Stable production of high-quality and low-cost feeds is a key to effective Animal Husbandry. Perennial grasses are the most popular source of fodder. Introduction of new unconventional genotypes of such grasses carrying improved economically important traits is crucial for forage production. Festulolium intergeneric hybrid is a valuable crop that can be used to produce green forage, hay, silage, haylage as well as to maintain pastures and grasslands. Its large-scale cultivation requires new techniques providing high and stable yield. Seeding rate and pattern significantly affect festulolium performance. This paper reports on festulolium biological parameters and seed productivity analyzed in 20062009. Row and skip-row planting patterns as well as the seeding rate of 6.0 kg ha-1 resulted in sparse lodging-resistant swards. Seeding rates of 6.0 and 9.0 kg ha-1 provided the highest photosynthetic potential 10291090 thousand m2days ha-1. High plant density (up to 12.0 kg ha-1) negatively affected festulolium performance and led to lodging. The seeding rate of 6.0 kg ha-1 and festulolium density of 130133 plants/m2 resulted in the highest seed productivity: 604.3 and 652.3 kg ha-1 under row and skip-row planting patterns, respectively.

The results of the analysis of yield and biological efficiency of single-species and mixed crops of cereals and legumes, depending on the cultivation zones, are presented. The study was carried out in the forest-steppe and steppe zones of Western Siberia and the forest-steppe zone of Eastern Siberia. The results were analyzed by means of Land Equivalent Ratio and the coefficient of aggressiveness. In the forest-steppe zone of Western Siberia, two-component mixtures with a seeding rate of 60– 75% of cereals (barley or oats) and 35–50% of legumes (peas) had an advantage in cultivation for fodder grain. The yield was 2.3–2.9 t/ha of grain with digestible protein content of 106–110 g per feed unit and the efficiency of the area use of 1.17 units. Peas mixed with wheat had the highest coefficient of aggressiveness (plus 0.53). In the conditions of the steppe zone of Western Siberia, two-component mixtures of barley and wheat with field peas are the most effective with a ratio of cereal and legume components of 60/50% of the total seeding rate of crops. The yield of these cenoses was noted at the level of single-species crops, and the nutritional value was 6–10% higher. Land Equivalent Ratio for this zone amounted to 1.21-1.3 units. The share of the legume component in the grain yield of three-component mixtures under unfavorable dry conditions of the steppe zone was registered insignificant. The value of the coefficient of aggressiveness of the legume component decreased to minus 1.58 and its share in the agrocenosis decreased to the utmost extent. The foreststeppe zone of Eastern Siberia is characterized by sufficient moisture, which contributed to a good grain harvest. The highest yield was provided by a mixture of oats with peas (4.85 t/ha) and oats with peas and barley (4.29 t/ha), with the Land Equivalent Ratio of up to 1.45 units and the coefficient of aggressiveness close to zero. In this zone, there are favorable growth conditions for binary crops.

Among the factors that determine the efficiency and success of the livestock industry is the science-based production of high quality feed. The solution to this problem is impossible without field feed production, engaged in the cultivation of annual mixtures. Among the large number of forage crops in the western forest-steppe are worthy of annual mixtures, in particular winter, which is highly valued for adaptability to growing conditions, especially in climate change. Despite the considerable part of the conducted researches on the development of technology of cultivation of winter forage crops, the question of optimization of their component composition and increase of stability of the most economically valuable species in the conditions of climate change remains relevant. Field studies were conducted in accordance with the common methods of forage production at the collection and research field of the Separate unit of the National University of Bioresources and Nature Management of Ukraine «Zalishchyky Agricultural College. E. Khraplyvy» during 2016-2018. On the basis of the experimental data, the optimal elements of the technology of cultivation of agrophytocenoses of Pannonian Viking with rye winter and triticale winter for the conditions of the Western Forest Steppe were identified. It was found that the highest yield of 1 ha of fodder units and exchange energy among the grass-root mixtures (4.50 t and 62.8 GJ) was agrophytocenosis, which included the cultivation of Pannosk in the amount of 2.5 million / ha of similar seeds with winter rye - 75% of the total sowing rate in single-species sowing, and among the ex-tritical (5.09 t and 64.6 GJ) - variant with sowing of the same seeding rate of legume component and winter triticale - 25% of the total sowing rate in single-species sowing. Pannonian wiki seeds in both variants were treated before sowing growth promoter. The results of the research will help to strengthen the forage base for animal husbandry and increase the productivity of farm animals.

Soil Response

Soil compaction after sowing reduces overall porosity, increases thermal conductivity and heating of the upper layer, which increases the contact of seeds with the soil, accelerates water consumption, swelling and germination of seedlings of crops. Currently, the most part of drills, including seeding systems, press the soil by the rolls of different modifications simultaneously with sowing. After sowing crops, the upper (0-10 cm) soil layer has insufficient compaction (less than 1.00-1.05 g/cm3) and increased non-capillary porosity (more than 50%), which leads to moisture losses from the upper layer. The researchers found out that rolling-up contributes to increasing of the top layer clumpiness on 5.8% on average and reduces erodability of the field surface on14.4% with weak soil response to deflation (less than 50 g). The experimental results on effectiveness of additional pressrolling after sowing SKP-2.1 on the fall variants of the steam field treatment to a depth of 20-22 cm showed that seed germination was increased on 11.3%, and grain increase was 0.09-0.15 t/ha or 4.2-7.2%. On minimal steam treatment, (depth of 10-12 cm) additional soil press rolling was not sufficiently effective. On the black-earth soils of the forest-steppe of Western Siberia, press-rolling of the soil after sowing SKP-2,1 contributes to additional grain yield of winter rye and durum wheat to 0,14-0,23 t/ha (6,1-11,0 %). Additional rolling after sowing by SKP-2,1 and John Deere 1820 with pointed tines for autumn backgrounds increases grain yield in the second wheat after steam from 2.52 to 2.74 t/ha, or 8.7%.

The results of research (2016-2018) into productivity, adaptability and nutritional value of poaceous crops (forage millet, Sudan grass) and legumes (fodder beans, spring vetch, garden peas) are presented and analyzed. The research was conducted on meadow chernozem mealy-carbonate soil, light loam by granulometric composition, in the forest-steppe zone of Trans-Baikal Territory. Agricultural technology used for fodder crop cultivation was common for this area. The objects of the research were legumes (Sibirskiye forage beans, Novosibirskaya spring vetch, Holik garden peas), and poaceous varieties (Bystroe forage millet, Novosibirskaya 84 Sudan grass). The experimental work was carried out in accordance with the generally accepted guidelines for field experiments. All the forage crops under study have formed a fairly high productivity: the yield of green mass was 13.0-18.2 t/ha, dry matter – 2.6-3.2, feed units – 2.2-2.7 t/ha, digestible protein – 220-567 kg/ha, gross energy – 26.5-32.2 GJ/ha, with availability of digestible protein 100-210 g per one feed unit. Among leguminous crops, spring vetch and fodder beans had an advantage with the green mass yield of 13.3-15.0 t/ha, the amount of dry matter of 3.1-3.2, feed units of 2.6-2.7 t/ha, digestible protein 494–567 kg/ha, gross energy 32.0–32.2 GJ/ha, with availability of digestible protein of 190–210 g per one feed unit. Garden peas were inferior to spring vetch and fodder beans in yield by 2.3-13.3%, dry matter – by 9.6-12.5, feed units – by 3.8-7.4, digestible protein – by 4.9-17.1, gross energy – by 8.1–8.7%. Among poaceous crops, agrocenoses of Sudan grass had an advantage in productivity and nutritional value. They formed the yield of green mass 18.2 t/ha, the amount of dry matter 3.1, feed units 2.5 t/ha, digestible protein 300 kg/ha, gross energy 31.3 GJ/ha, with availability of digestible protein of 120 g per one feed unit. Fodder millet was inferior to Sudan grass in all respects by 12.0–26.7%, respectively.
