The purpose of the research is to determine the duration of the interphase period, total water consumption, plant height, yield and quality of sunflower seeds, depending on the characteristics of hybrids and foliar top dressing with microfertilizers. Methods. Experimental studies were conducted during 2020–2021 in the experimental field of Mykolaiv National Agrarian University (Ukraine). Results. It was determined that all the studied microfertilizers extended the duration of interfacial periods of sunflower plants. The largest total water consumption of sunflower plants (2259 m3 /ha) was formed in the hybrid NK Kamen in the variant with foliar top dressing with microfertilizer Quantum, which was 0.9–6.5% more than in the same variant with hybrids Darius and Tutti. The highest height of sunflower plants among the hybrids submitted for study was formed by Darius – 165.7–170.9 cm, which was 5.0–5.7% higher than the height of plants of the NK Kamen hybrid and 7.2–8.0% more than the height of Tutti hybrid. It was found that the highest yield of sunflower seeds (2.55 t/ha) on average over the years of research was formed in the hybrid NK Kamen in the variant with foliar top dressing with microfertilizer Quantum, which exceeded its level in the non-fertilized control by 18.6% and the average yield for all variants of the experiment by 12.3%. The highest yield of sunflower seeds (2.56 t/ha) among the hybrids submitted for study was provided by NK Kamen in 2021, which was 12.3% more than in the Darius hybrid and 6.6% more than in the Tutti hybrid. Foliar top dressing with microfertilizers significantly affected the quality indicators of seeds of the studied sunflower hybrids. The maximum fat content values (from 50.1 up to 52.7%, depending on the hybrid) were achieved by applying Quantum microfertilizer in the 5-6-leaf phase. The conditional yield of oil from seeds in this variant of nutrition is also determined to be the maximum – from 1.13 up to 1.34 t/ha, depending on the hybrid. Less effective for the growth and development of plants and the formation of their productivity was the preparation Rostok, with the introduction of which the duration of the growing season increased by 1-2 days; total water consumption increased by 29–35 m3 /ha; the height increased by 1.1–4.6 cm; seed yield increased by 0.80–0.28 t/ ha; the content fat in seeds increased by 0.02–0.03%; oil seed yield increased by 0.12–0.15 t/ha.

The article highlights experimental and field studies of the scientific problem of increasing the yield of soybean seeds by optimizing the main elements of growing technology. Improved standards for the depletion of major biological nutrients during the formation of units in soybean crops make it possible to specify the standards of foliar fertilization to obtain the planned levels of yield and removal of these elements from the soil. The obtained results are of practical importance, as they contribute to optimizing the nutrition of soybean plants due to the use of foliar fertilizers Ecoline Legume. This helps to increase seed yield to the level of 2.0–2.5 tons per hectare. The researchers also conducted a generalization and analysis of scientific results in the field of soybean yield management through foliar feeding. In addition, scientific publications on the influence of liming, application of organic, mineral and microfertilizers on the physicochemical and agrochemical properties of the soil were analyzed. The cultivation of soybeans and the rational application of foliar fertilization are economically beneficial methods, and in this case, the use of foliar fertilization Ecoline Legume to approximately neutral reaction of the soil environment contributed to obtaining the highest levels of conditional net profit and profitability. This confirms the high energy efficiency of soybean cultivation.

The effects of macro- and microfertilizers, soil reaction and soil fertility on the yields and quality of long-fibre flax in rotation were studied. The paper generalizes lasting data (1982 - 1991) on the effect of dressing conditions on the yields and quality of long-fibre flax in rotation depending on soil fertility level and soil liming. The doses of the main fertilizer N₄₅P₉₀K₁₂₀ on the background P₂O₅ – 100 - 130, K₂O – 110 - 140 mg/kg soil, pH salty – 5.0 - 5.4 and N₃₀P₆₀K₉₀ on more fertile soil with content P₂O₅ up to 280 - 300, K₂O – 240 - 280 and pH salty 6.0 - 6.2, were considered more effective for flax according to qualitative and quantitative traits. The negative effect of full lime doses is smoothed over hy application zinc containing fertilizers. It was found out that local fertilizer application is an essencial element of power saving and nature protecting fertilizeration system. In comparison with broadcasting its introduction in farm production will give the possibility to decrease the fertilizer requirements by more than 30% and to increase power output by 27 - 44% per 1 ha.
