Abstract. The purpose is to study the effect of various siderates on the biological properties and yield of spring barley. Methods. Тhe experiment was carried out on podzolized chernozem in 2017–2018 in the forest-steppe zone of the Middle Urals. The green mass of the siderates was taken into account manually, and barley grain by combine was carried out. Soil moisture was determined by the thermostatic-weight method. The number and mass of earthworms were determined from the registered area. The microbiological activity of the soil was determined by the method of linen cloths. Scientific novelty. For the first time, the effect of various siderates on the yield of spring barley and the microbiological activity of the soil, the number and mass of earthworms was compared on podzolized chernozem. Results. The effect of various siderates: peas + oats, winter rye, spring rapeseed, white mustard, fodder beans on the microbiological activity of the soil, the number of earthworms and the yield of spring barley in the link of the field crop rotation – sideral steam – spring barley was studied. The largest green mass of green manure was plowed into the soil in the following variants: fodder beans (41.2 t/ha) and peas + oats (36.4 t/ha). In the variant with the planting of fodder beans, the highest microbiological activity of the soil was observed (71 %). Studies of the number of earthworms showed that their number was 24 % higher in the mustard variant compared to the control. However, the mass of the soil they processed in the peas + oats variant (138 g/m2) was maximum and exceeded the mass in other versions by 11–27 g/m2. The highest yield of barley was also obtained in the variant with the incorporation of feed beans – 2.87 t/ha, which is 0.26–0.69 t/ha higher than the rest. Increasing the microbiological activity of the soil in the variant with the incorporation of feed beans increased the yield of barley. The increase in the plowed green mass in the variants did not affect the increase in the number and weight of earthworms.

The Right

The influence of long-term application of different doses and ratios of mineral fertilizers in field crop rotation on the content of basic nutrients in grain and straw of spring barley has been established. The study was held in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine. The relative nutrients removal by spring barley depending on the doses of different types of fertilizers and their combinations in the field crop rotation is calculated. It is shown that the content of basic nutrients in the harvest of spring barley (grain and straw) significantly depends on the content of their mobile compounds in the soil. This is especially true of nitrogen and less of potassium. Economic removal of nutrients from the grain harvest of spring barley depends on the doses of fertilizers in the field crop rotation and the ratio of nutrients in them. The largest share is nitrogen (65–122 kg / ha), followed by K2O - 47–92 and P2O5 26–51 kg / ha. From 1 ton of grain and the corresponding amount of straw, spring barley of the Commander variety removes 19.2–22.4 kg of nitrogen, 7.8–9.2 - P2O5 and 14.0–16.8 kg of K2O from the soil, depending on the fertilizer and saturation of field crop rotation with different types of fertilizers. Straw is an important source of soil organic matter reproduction and the return of nutrients used for crop formation. Depending on the system of fertilization, 17–25% of nitrogen, 25–30% of phosphorus and 68–69% of potassium are returned to the soil with spring barley straw via economic removal. It is specified that spring barley of the Commander variety absorbs N, P2O5 and K2O in the following ratio: 1: 0,4: 0,3 to form a unit of grain yield and the corresponding amount of straw in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe.

The Right

The influence of long-term application of potassium-deficient fertilizer system in the field crop rotation (winter wheat, corn, spring barley, soybeans) on podzolic heavy loam black earth of the Right-Bank Forest-Steppe of Ukraine on potassium content in plants, its costs for formation of one unit of the harvest was determined; potassium balance was calculated and the effectiveness of different doses of potassium fertilizers was comprehensively assessed. It was found that the potassium content in grains and seeds of agricultural crops under the influence of potassium fertilizers varies by no more than 8%, while in straw and stalks - by 10-24% depending on the variant of the experiment. It is shown that the non-grain part of the crop contains a significant part of potassium - 50-80% of economic removal depending on the crop. It is calculated that if it is left in the field for fertilizer in the variant of the experiment Basis + K80, it compensates for the consumption of potassium by 71%. By applying K40 and K80on the basis of applying N110P60 and leaving the non-commodity part of the crop in the field for fertilizer, the balance of potassium in the soil is formed positive with intensity of 111 and 212%, respectively. According to the index of complex assessment, which takes into account seven indicators: payback of 1 kg of mineral fertilizers; additionally conditionally net profit; net energy profit; humus balance and intensity of nitrogen, phosphorus and potassium balance, the best variant of the experiment is application of N110P60K40 per 1 ha of field crop rotation area. This indicates the possibility of a temporary reduction in the dose of potassium fertilizers in field crop rotation on podzolic heavyloam black earth in the Right-Bank Forest-Steppe of Ukraine

The aim of the research is to take a comparative assessment of the amount of plowed down plant residues in various field crop rotations in the conditions of the Republic of Mari El. The study was carried out in 2013-2018 on a stationary site in a two-factor experiment. Factor A ‒ types of crop rotations and shift of crops: 1. Grain and grass crop rotation (oats + clover, clover of the 1st year of use (y.u.) for green mass, winter rye, vetch and oat mixture for grain, spring wheat, barley. 2. I fruit-changing crop rotation (vetch and oat mix for green fodder, winter rye, barley, potato, vetch and oat mixture for grain, spring wheat). 3. II fruit-changing crop rotation (vetch and oat mixture for grain, spring wheat, potato with manure (80 t/ha), barley + clover, clover of the 1st year of use for green mass, winter rye). 4. III fruit-changing crop rotation (barley + clover, clover of the 1st year of use for green mass, clover of the 2nd year of use for green mass, winter rye, potato, oats). Factor B ‒ mineral fertilizers: 1. Without fertilizers. 2. N60P60K60. In the control grain and grass crop rotation with a oneyear use of clover, 3.02±0.06 t/ha of crop-root residues were received per year on the average. In the I fruit-changing crop rotation, due to the replacement of clover with potato, residues formed 2.14±0.04 t/ha, which was significantly less than the control variant (LSD05 in factor А ‒ 0.21). In the II fruit-changing crop rotation, the accumulation of crop-root residues amounted to 2.91±0.07 t/ha. Compared to the control, it was within the limits of experimental error. The largest number of crop-root residues was accumulated in the III fruit-changing crop rotation (3.37±0.07 t/ha). The use of mineral fertilizers significantly increased the bulk of crop-root residues in all crop rotations by 0.16 t/ha per year on the average (LSD05 in factor B ‒ 0.15). Carbon to nitrogen ratio (C:N) in the crop-root residues of clover and potato was 18…20, in the vetch-oat mixture it was 25…31, in spring grain crops it was 39…41, and in winter rye it was 53.

У статті наведено результати досліджень впливу використання мікроелементного препарату «Аватар», що застосовувався для обробки насіння ячменю ярого і під час вегетації рослин культури, на поширення хвороб ячменю та врожайність зерна. У результаті польових досліджень було встановлено, що в зоні недостатнього зволоження в умовах південно-східного Лісостепу України в польовій сівозміні використання мікроелементного препарату «Аватар» для дворазового позакореневого підживлення рослин ячменю ярого під час вегетації, навіть за несприятливих агрометеорологічних умов (підвищена температура повітря, відсутність достатньої кількості опадів), сприяло одержанню врожайності зерна досліджуваної культури у межах 4,26–4,84 т/га. Обробка насіння протруйником «Авіценна» (0,4 л/т) і мікроелементним препаратом «Аватар» (300 мл/т) + два обприскування рослин під час вегетації «Аватаром» (200 мл/га) забезпечили найнижчу інтенсивність розвитку гельмінтоспоріозної смугастої плямистості на рослинах ячменю ярого – 10,5%, що обумовлено кращим розвитком рослин досліджуваної культури і більшою їх стійкістю проти хвороби. Після обробки насіння протруйником «Авіценна» (0,4 л/т) із наступними двома обприскуваннями рослин під час вегетації «Аватаром» (200 мл/га) ураження рослин ячменю ярого кореневими гнилями виявилось найменшим, зокрема, поширення й інтенсивність розвитку хвороби становили 0,3 і 0,1 % відповідно. In the zone of insufficient humidification, characterized by a sharp lack of atmospheric precipitation and soil moisture, the use of the micronutrient drug «Avatar» for the cultivation of various crops remains open, relevant and requires more systematic study. The purpose of the research was to determine the effect of using the micronutrient drug «Avatar», which was used for the treatment of spring barley seeds and during vegetation of crops, on the spread of barley diseases and grain yield. Field studies were conducted in the production experiment of the Veselopodil experimental and breeding station at the Institute of Bioenergetic Cultures and Sugar Beet at the National Academy of Agrarian Sciences of Ukraine (Semenivka district, Poltava region) during 2017 in long-term field crop rotation. As a result of field studies, it was found that in the zone of insufficient humidification in the conditions of the South-Eastern Forest-Steppe of Ukraine in field crop rotation, the use of the microelement preparation «Avatar» for two-fold extra-root feeding of spring barley plants during vegetation, even under unfavorable agro-meteorological conditions (elevated temperature regime, absence a sufficient amount of precipitation), contributed to the yield of grain yield of the studied crop in the range of 4.26–4.84 t/ha. The treatment of seeds by Avicenna (0.4 l/ton) and the microelement drug «Avatar» (300 ml/t) + two spraying plants during the «Avatar» (200 ml/ha) growth provided the lowest intensity of helminthosporia strain spotting on barley plants bright – 10.5 %, which is due to the best development of plants of the studied culture and their greatest resistance to the disease.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The article analyzes the current state and improvement of elements of the technology of growing valuable forage and food crops, spring barley in Ukraine. It is noted that in recent years the area under large crops and the yield of this crop have decreased significantly. It is emphasized that further improvement of technologies should be focused on the transition to more use of biological agents to increase yields. Researchers have shown that the effectiveness of the use of humid preparations GK-6M, GK-4MK, GK-MK - on crops of spring barley Dokuchaivsky 15, due to foliar feeding of plants in the tiller ring phase. The main justification of the article is the results of field research conducted in 2015–2019. Maximum indicators, namely: increase in leaf area by 46–38 %, stem height by 8,3 cm; the number of grains in the ear – 4,8 pieces; ear lengths – 1,9 cm; mass of grain in the ear – 0,33 g; masses of 1000 grains – at 12,0 %; nature of grain – 34,9 g – was obtained by treating plants with humid preparation GK-6M. Foliar feeding of plants in the tiller ring phase with the studied drugs provided the largest increase in the yield of spring barley grain – 1,08 t/ha, provided the use of growth stimulant GK-6M. A slightly smaller effect of foliar fertilization of plants on the yield of spring barley was observed from the growth stimulator GK-4MK – the increase in grain yield was 0,83 t/ha and from the growth stimulant GK-MK – the increase in grain yield – 0,66 t/ha. The obtained increments are significant, mathematically proven. Further improvement of agrotechnologies due to wider use of biological means of increase of productivity and quality of production is offered.
