Innovative aspects of increasing the yield and quality of corn grain in Western Siberia

Abstract

The results of three years of research (2021-2023) to study the effectiveness of using growth stimulants on corn when grown for grain are presented. It has been shown that on leached chernozem in two ecological points of the Novosibirsk Ob region TPP “Praktik” of the Novosibirsk region, CJSC breeding plant “Irmen” of the Ordynsky district of the Novosibirsk region, growth stimulants increased the growth rate and development of corn when grown for grain. In experiments, the effect of growth stimulants on the yield and quality of grain of three F1 corn hybrids of early ripening was studied: Kubansky 101, Kubansky 102 and Katerina. Growth stimulants were used by pre-planting seed treatment, spraying in the fourth leaf phase and at the beginning of flowering of corn plants. Growth stimulants increased the yield of corn grain by 33% relative to the control (water) in the hybrid Katerina F1. A significant improvement in the biochemical composition of corn grain was noted with the use of growth stimulants: an increase in protein content by 0.4-0.8%, BEV and fat.
