In the course of the study (2012-2014) there was revealed the effect of the microbial preparation (Rizobofit) and plant growth regulators (Gumaksid and AKM) on the symbiotic nitrogen fixation, photosynthetic activity and grain productivity in garden pea. Experiments were conducted six times in accordance with the methodology and techniques provided for laboratory and field studies. We used common methodologies to determine leaf area, photosynthetic potential, dry mass, net photosynthetic productivity, the number of active tubers, yield indices and nitrogen content. The results show that the use ofthe biological product in combination with plant growth regulators to treat seeds and vegetative pea plants stimulates the photosynthetic activity, increases net photosynthetic productivity, provides grain yield increase of 0.87 - 1.79 t/ha with the biological yield in the control group of 2.45 t/ha, increases protein yield from 1 hectare by 1.6 - 2.2 times compared to the control group through the enhanced symbiotic nitrogen fixation and biological nitrogen assimilation.
