Abstract

The contribution of different nitrogen sources (nitrate 15 N-NO 3 and symbiotic N-N 2 ) to the nitrogen status of soybean in ontogenesis was studied. Nitrate was assimilated effectively during the vegetative growth, whereas later on the nitrogen-fixation by root nodules became the basic source of nitrogen. The applying of a low dose of nitrate (22.2 mg N/plant) increased the total nitrogen content in the plant and did not depress the nitrogen fixation. Distribution of the symbiotic and nitrate nitrogen among organs of soybean was proportional.
