Effect of rhizobacteria Paenibacillus polymyxa KB and chelate complex of biogenic silicon on photosynthetic pigments and yield of corn grain

Abstract

We used corn seeds from maize (Zea mays L.) of the Dnieper 196 SV hybrid to analyze pre-sowing seed bacterization and treatment with biogenic silicon that could be promising in growing maize hybrids. The chlorophyll content in the leaves of corn plants gradually increased in growth phases and reached its maximum in the phase of milky ripeness of grain under the presowing seeds bacterization with Paenibacillus polymyxa KB and seed treatment with Biogenic Silicon (BSi). The corn yield during both variants of seed treatment increased, exceeding the control by 28.8% and 23.4%, respectively. Both variants of presowing seed treatments are promising in the growth of maize hybrids.
