Abstract

The results of studies on the influence of organic fertilization using straw, siderates, manure, the latest organic fertilizers "Biohumus", "Bioproferm" on improving soil fertility and forming the productivity of the soybean agrocenosis are given, and the economic efficiency of agricultural measures is determined. The improvement of agrophysical and agrochemical parameters was established, the trend of increasing the content of humus in the soil by 0.08-0.17 %, the decrease of the acidity of the pH of salt by 0.5-0.8 compared to the control was noted. In all variants of the experiment, improvements in biometric indicators of agrocenosis formation, increase in leaf surface area, net productivity of photosynthesis, indicators of accumulation of dry matter were noted. The researched elements of the growing technology affected the reduction of weediness of soybean crops, contributed to the increase in the formation of the number of beans per plant and the weight of 1000 seeds. With the use of elements of organic fertilizer in all variants of the control, the productivity of soybean varieties Bohemians and Suzirya increased, with the highest productivity indicators of 3.58 and 3.29 t/ha, respectively, which is more by 1.32 and 1.26 t/ha. The improvement of quality indicators of soybean grain was established. The largest conditionally net income of the Bohemian and Constellation varieties was obtained in the variant of straw destruction with the preparation "Vermystim-D" (7 l/ha), application of organic fertilizer "Bioproferm" (4 t/ha) with the following sowing of white mustard on siderate: respectively by 8.65 and 8.54 thousand hryvnias/ha; profitability level – by 18.4 and 28.2 %; the cost price decreased by 0.35 and 0.61 thousand hryvnias/ton compared to the control.
