https://doi.org/10.18384/2224-0209-2011-3-439
Abstract
The effect of starting dose of nitrogen on the formation of root nodule and symbiotic system, and also on the activity of nitrogen fixation and nitric nutrition of soybean plant was studied. It is supposed that the use of small dose of nitrogen (25 mg N/plant) in the beginning of vegetation period, despite luck of mineral nitrogen in medium, on the beginning of flowering until seed ripening produces favourable conditions for the functioning of symbiotic system, thereby facilitates the normal formation of beans and total nitrogen reserves of plant.
