REUTILIZATION OF PLASTIC SUBSTANCES, NITROGEN AND PHOSPHORUS IN SOYBEAN PLANTS

Abstract

The article presents the results of studies on the dynamics of the content of dry matter, total nitrogen and phosphorus by individual organs of soybean plants. The number of nutrients that can be remobilized, that is to translocate from vegetative organs to generative organs soybean during grain ripening is determined. The remobilization of dry (plastic) substances was 9,9-16,1 %. The outflow of mobile nitrogen and phosphorus compounds from the vegetative organs to the ripening soybean grain was about 66 % of the maximum content during vegetation. The contribution of reused nitrogen in the formation of yields was 70 %, and phosphorus - 66 %.
