The indicators of photosynthetic activity and productivity of spring wheat crops are given with an analysis of changes in plant leaf area, photosynthetic potential, net productivity of photosynthesis and yields on spring wheat crops at different seeding rates and treatment of seeds and crops with liquid mineral fertilizers MEGAMIX. As a result of the research, it was found that the leaf area and photosynthetic potential increased on wheat crops with a seeding rate of 4.5 million viable seeds per hectare. The maximum indicators are formed when seeds are treated with MEGAMIX Seeds 2 l/t followed by two foliar applications with MEGAMIX Profi 0.5 l/ha (at the tillering stage (29 VVSN)) + MEGAMIX Nitrogen 0.5 l/ha (at the flag leaf stage) (39VVSN)). The maximum leaf area of 23.7 thousand m2/ha and the photosynthetic potential of 0.956 million m2/ha days are formed here. This option provides a yield of 3.69 t/ha.
