Productivity of soya bean depending on inoculation and fertilizers in conditions of Polisya of Ukraine

Abstract

The purpose. Detection and justification of influence of norms of artificial fertilizers, inoculations of seeds and foliar application on formation of productivity and quality of soya bean in Polisya. Methods. Agrochemical (for determination of chemical composition of soil, plants), mathematical (dispersing), biometrical (for determination of formation and activity of symbiotic apparatus). Results. Formation is shown of tubercles depending on inoculation of seeds and foliar application on the background of artificial fertilizers. The amount of biological nitrogen and equivalent of ammonium nitrate is calculated. It is fixed that inoculation and foliar application on the background of artificial fertilizers in dose of N60P60K60 promotes formation of tubercles on a rootage (73 pieces in comparison with alternative without fertilizing). Conclusions. Increase of crop of early ripening variety KiVin at application of artificial fertilizers in dose of N60P60K60, inoculations and foliar application has made 1,3 t/hectare.
