It is known that the growth and development of plants, including vegetable peas, depend on the presence and assimilation of nutrients by plants from the soil and their photosynthesis. With the deterioration of the stages of the process of one of the components changes the passage and functions of the other, which are one whole process of plant nutrition. Conducting the research, on average, during the period of full germination-technical maturity in the control variant with the application of mineral fertilizers N30P60K60, and pre-sowing treatment of seeds with rhizotorphin photosynthetic potential in pea varieties Skinado and Somerwood was 2.039 and 2.254 million m2 / day. While pre-sowing treatment of seeds with microfertilizer Vuxal Extra CoMo against the background of mineral fertilizers N30P60K60 and pre-sowing treatment of seeds with Rhizobophit in pea varieties Skinado and Somerwood compared to the control photosynthetic potential increased by 0.472 and 0.530 million m² di. The maximum indicators of photosynthetic potential in the varieties Skinado - 3,078 and Somerwood - 3,427 million m² days / ha were obtained on the variant of the experiment, where liming was carried out (1.0 norms per hectare) against the background of mineral fertilizers N30P60K60 and pre-sowing seed treatment Rhizobophit and microfertilizer Vuxal Extra CoMo and applied foliar fertilization with microfertilizers Vuxal Microplant during vegetative growth and Vuxal Calcium, Boron during budding. Depending on liming and foliar feeding the increase in dry matter reaches its maximum in the phase of technical maturity This is 1.020 and 1.173 million m² / day more than in the control. In the same variant, the maximum rates of dry matter growth were observed in Skinado varieties - 6.23 and Somerwood - 7.39 t / ha, which is 1.42 and 1.43 t / ha more than in the control.
