Results of research on the influence of nitrogen fertilizers and biologically active compounds on forming of yield structure and biological yield of soybean on typical black soil are given in the article. It was established that increase of nitrogen fertilizers rates in whole has positive effect on soybean yield formation. But if application of nitrogen fertilizers at rate 60 kg/ha (on background of P60K60) favors to increase in yield the further increase of nitrogen fertilizers rate up to 120 kg/ha leads to reduction of this parameter. On research variants with application of high rates of nitrogen fertilizers because of absence of nitrogenize activity of nodules on soybean roots fixation of nitrogen from air did not occur and plants supplies with nitrogen only from mineral form. Inoculation of seeds together with application of medium rates of mineral fertilizers (N30-N60 on background P60K60) favors to significant increase in yield of grain of researched crop.
