THE STARTING DOSES OF NITROGEN AND SYMBIOSIS OF SOYBEAN WITH NODULE BACTERIA
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.
