The influence of agrochemicals on photosynthetic activity and the yield of grain corn hybrids in the Lower Volga region
Year: 2024
Type: article
Abstract: The maximum leaf surface area on average over three years of research was with the combined application of mineral fertilizers (NPK) and growth-stimulating preparations (Agree`s Boron, Agree`s Aminovit) - 25.8 thousand m2/ha for the hybrid Krasnodar 385 MV. Significant variations in net photosynthetic productivity indicators were in corn hybrids depending on the experimental options used. The net productivity of photosynthesis of corn hybrids varied from 4.6 to 6.7 g/m2 day. The hybrid Krasnodar 385 MV was characterized by the minimum values of this trait; the maximum value had the hybrid ROSS 199 MV. The maximum yield of grain corn hybrids on average over three years was after the application of NPK + Agree`s Boron + Agree`s Aminovit. Grain yield varied from 5.59 to 6.15 t/ha.
