The authors showed the results of studies of productivity parameters of different early maturing maise hybrids depending on the method of sowing. Experiment included 5 variants: single- seeded hybrids Kubansky 101 and Kubansky 500, Kubansky 101 + Kubansky 500 (50 + 50% of the full seeding rate), Kubansky 101 + Kubansky 500 (25 + 75%) and Kubansky 101 + Kubansky 500 (75 + 25%). The authors carried out a biological yield survey on 10 September. This recording showed that the ultra-early-ripening hybrid Kubansky 101 CB was in the phase of milk-wax maturity of the grain, and the late-ripening Kubansky 500 CB was in the phase of cob formation. In single-species crops, the yields were naturally higher. The late-maturing hybrid yielded 82.0 t/ha, 38.1 t/ha higher than the ultra-maturing hybrid. However, the dry matter yield of the second hybrid was 15.9 % higher, and the cob yield was 29 % higher. The dry matter concentration of the hybrid Kubansky 500 was only 18.8 %. The hybrid Kubansky 101 CB had a dry matter concentration of 34.7 %. Different variations with the ratio of hybrids of different ripeness groups in the sowing showed that in green matter yield, the variants where the proportion of late-ripening hybrid is higher are superior. Thus, the presence of 75% hybrid Kubansky 500 CB allowed obtaining the highest yield of 77.2 t/ha. This yield is almost two times higher than the yield of the single-variety ultra-ripening hybrid (43.9 t/ha). However, the dry matter concentration here was 20.2 %. According to the biochemical analysis of the silage batches harvested, all the forages were benign. No oily acid was detected, and lactic acid predominated over acetic acid. Hay prepared from hybrid Kubansky 101 SV was 33.8% in dry matter content, which compares favourably with silage prepared from hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV. The hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV accounted for 21 % dry matter content. In silage prepared from hybrid Kubansky 101 SV, the percentage of dry matter is 24.2-25 %.

The article presents the results of studies of the effect of seeding rates and row spacing on the forage productivity of different alfalfa ecotypes when mowing grass in the flowering stage. In the soil-climatic conditions of the right bank forest-steppe irrespective of the effect of abiotic and biotic factors during the growing season, high adaptability of alfalfa of the southern ecotype of the Angelica variety was established, which formed a stable crop of green mass at the optimal seeding rate (8,0 million/ha) and width 12,5 cm. For an average of two years of grass use, the varieties of alfalfa Rosana and Angelica provided a yield of green mass of 62,96-64,02 t/ha, which was 11,1-14,9% higher than for sowing with the norm of sowing 4,0 million/ha, and 6,3-7,1% with row spacing half (25,0 cm). It was found that in two years of use of alfalfa Angelica variety had higher dry matter content, compared with the variety of Rosana and were respectively 23,05 and 22,98%. There was a gradual decrease in the dry matter content with a thickening of the herbage in the Rosana variety from 23,32 to 22,72% and from the Angelica variety from 23,31 to 22,84%. As the row spacing increased from 12,5 to 25,0 cm, the solids content increased by 0,28-0,62%, or 22,74-22,84 and 23,12-23,36%. The crude protein content in the dry matter of alfalfa plants of both varieties differed by slopes and years of herb use. The highest content of crude protein was obtained in the dry matter for sowing with a row spacing of 12,5 cm, which averaged 21,10% in the Rosana variety and 20,23% in the Angelica variety or increased by 0,79-0,87%, compared to the row spacing of 25,0 cm. Thus, irrespective of the hydrothermal conditions during the growing season of the studied varieties of alfalfa sowing Rosana and Angelika, the average yield of dry matter at the level of 13,64-13,93 and 2,76-2,88 t/ha of crude protein at the width of row 12,5 cm. Key words: alfalfa, variety, flowering start, crude protein, dry matter, yield, green mass.

The average data for 2018–2019 are presented for yield, dry matter content in grain-haylage mass, nutritional value of test grain-haylage samples produced from plant mass of white lupin, oat and Sudan grass from single and mixed cenosis of different sowing times. The grain-haylage mass was harvested in the phase of brilliantly ripening lupin bean, milky-waxy ripeness of oats and the end of flowering of the Sudan grass. It’s revealed that variants of the second sowing date — 2 decade of May — have the best yield of grain-haylage mass and its dry matter content. The yield of grain-haylage mass in the best variants of the second sowing period exceeded by 7–8 t/ha. According to the nutritional value of grain silage samples (the content of metabolic energy, crude protein, crude ash and carotene), the best results were obtained in most variants of the first sowing period. In content of the metabolic energy and crude protein of 1 kg of dry matter of grain-haylage, the best were variants of the single-species cenosis of lupine and its mixture with oats of the first sowing period. Variants of single-species sowing of lupine and Sudan grass were distinguished by the content of carotene.

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.

Production practices that included two seeding methods and seven seeding rates in one study, and a combination of seven seeding and five harvest dates in another, were compared in field studies over a five-year period. Data were collected on dry matter yield and several plant characteristics. The lowest seeding rate in the row plantings produced the highest yield of dry matter every year. Seeding rates had no effect on yield within the broadcast method. Plant weight, stem diameter and leaf content were greater under the row seeding method than under the broadcast system, but none was affected strongly by seeding rate under either method. Plant height and dry matter content at harvest were not affected either by the methods or by the rates of seeding used. On the other hand, date of seeding had a marked effect on the final dry matter content and yield. Early seeding dates produced the highest yields. Dry matter yield increased several-fold throughout the autumn harvest period where mid- to late-season seedings were employed.

The aim of the research was to study the effectiveness of an application of increasing doses of potash fertilizers in the potatoes cultivation of the middle-early ripeness group of Gala variety on the background of the use of nitrogen-phosphorus fertilizers and sulfur in the dose of N90Р120S30. Studies were carried out in 2016-2018. The soil of the experimental site of gray forest medium loamy granulometric composition had the following agrochemical characteristics: pH of salt extract - 5.4-5.7; humus content - 3.28-3.41%; easily hydrolyzed nitrogen - 146-160 mg per kg; mobile phosphorus - 140-152, exchangeable potassium - 146-160 mg per kg of soil. Potassium fertilizers were applied in increasing doses - К30, К60, К90, К120, К150, К180 kg of the active substance together with the background fertilizers - N90Р120S30 and microelements deficient in this soil: copper, boron and molybdenum in the composition of ZhUSS-1 and ZhUSS-2. The influence of the studied doses of fertilizers on crop yield, dry matter content, vitamin C, starch and nitrates has been established. On average of three years, the productivity of tubers was 21.67 tons per hectare. When applying background fertilizers (N90Р120S30) compared with the control, it increased by 4.32 tons per hectare. The optimal dose of potash fertilizer on the background of N90Р120S30 for potatoes grown under irrigation was К150, where the average yield of three years was 34.42 tons per hectare. A further increase in the dose of fertilizers did not significantly increase the productivity. On average of three years, the highest dry matter content was 22.81% and starch - 13.15% was noted in the variant, where potassium was applied in a dose of К180 kg of the active substance together with background fertilizers and microelements. With the introduction of high doses of potassium (К150 and К180 kg of the active substance), the content of dry matter and starch did not significantly differ from those in the control.

Purpose. To establish changes in the level of accumulation of raw ash, macro- and microelements, heavy metals and nitrates in dry feed biomass of different varieties of meadow clover depending on the elements of the growing technology in the Right Bank Forest-Steppe natural zone of Ukraine. Methods. Field and laboratory – for field and laboratory research, analytical – to determine mineral composition of dry meadow clover biomass. Results. Dry fodder mass of different varieties of clover under different elements of cultivation technology accumulated raw ash in the range of 8.5-8.9%, including macroelements (phosphorus – 0.32-0.37%, potassium – 2.21-2.52%, calcium – 0.49-0.58%, magnesium – 0.16-0.19%), nitrate nitrogen (N–NO3) – 0,02-0,05%, microelements (zinc – 13.7-14.8 mg/kg, copper – 3.5-4.9 mg/kg, manganese – 44.0-48.3 mg/kg and iron – 64.4-68.8 mg/kg) and heavy metals (lead – 1.8-1.9 mg/kg, nickel – 1.8-1.9 and cadmium – 0.2-0.3 mg/kg). Relation of dry matter content of potassium to the sum of calcium and magnesium content was in the range of 3.0-3.9 and calcium to phosphorus – 1.4-1.8. Conclusions. The content in the dry fodder mass of meadow clover of the studied macro- and microelements and their ratio did not exceed the zootechnical norms for feeding cattle. The method of sowing meadow clover did not significantly affect the accumulation of these mineral elements. Dry mass of the Lybid variety accumulated a little more potassium, and calcium and manganese were accumulated by the Typhoon variety. For the application of mineral fertilizers in doses Р60K90 and N60P60K90 compared to the variant where only inoculation of seeds with nodule bacteria was carried out an increase of crude ash, phosphorus, potassium in the dry matter content was observed. For the introduction of nitrogen at a dose of N60 without exceeding the maximum allowable concentrations, there was a slight increase in the content of nitrate nitrogen, as well as zinc, copper and manganese.
