Abstract
The article presents the results of research performed in a field stationary experiment on leached chernozem. In soy sowings of the Mageva variety, studied was the effectiveness of joint and separate application of various doses of mineral fertilizers and chelated form of microfertilizers (ZhUSS-2) in variants with soil previously limed in 0.5 and 1.0 h.a. The analysis of crop yield showed that the value of this indicator was significantly influenced only by mineral fertilizers, which provided an increase from 0.05 to 0.37 t/ha. as compared to the variant without fertilizers (0.89 t/ha, LSD 05 0.05 t/ha). An increase in the level of nitrogen nutrition from 45 to 60 kg a. i. / ha did not contribute to a significant increase in soybean productivity and reduced the payback of 1 kg of a. i. nitrogen by grain from 7.11 to 5.44 kg. The content of crude protein in soybean grain significantly increased as the result of the aftereffect of liming of the soil in 0.5 h.a. by 0.79 % (LSD05 0.33 %), of ZhUSS-2 preparation use ˗ by 0.19 % (LSD 05 0.16 %) and of mineral fertilizers use – by 0.26-4.02 % (LSD 05 0.22%). When full mineral fertilizer was applied, the concentration of crude fat decreased by 0.53-0.62 abs. %. Considering unfavorable weather conditions for sowing soybean crops on leached chernozem it is possible to recommend the application of mineral fertilizers in doses of N30P50K80 and N45P50K80 together with treatment of crops with ZhUSS-2 preparation.
