The results of several experiments conducted at different times by employees and graduate students of the Department of Crop Production, Feed Production and Agrotechnologies are generalized in the article. The preference of optimum seeding rate of soybean in wide-row (45 cm) - 550-600 thousand pieces/ha is shown. The high efficiency (synergism) of phosphorus-potassium (P90K60) fertilizer in a complex with pre-sowing treatment of seeds with ammonium molybdate solution (150 g/hectare) is revealed. An increase in the grain yield to the absolute control was 7.2 t/ha or 48.3 %, its protein content increased by 6.2 abs. %, and the oil content decreased by 0.3 abs. %. The foliar fertilization of vegetative plants of soybean with microfertilizers B (1 kg. hectare) + Mo (250 g/hectare) + ipin (50 ml. hectare) was highly effective, the yield increase was 4 c/ha (20%). Spraying of the ripen soybean with a 10% ammonium nitrate solution (25 kg/hectare) not only accelerated maturation of plants, but also increased productivity by 3,6 c/hectare (18%). The foliar fertilization of plants at a phase of 3-4 leaves with fertilizer Molytrac increased its productivity by 1.5 c/hectare (6,5%), and its combination with the second fertilizer Folicare (N18P18K18) increased the productivity by 3.2 c/hectare (13,8%).
