Abstract
In the arid conditions of the south of Kazakhstan, the problems of rational use of water resources and the introduction of effective irrigation technologies that ensure stable and high yields of corn for grain while maintaining soil fertility are of particular relevance. Currently, a promising technology for optimizing the conditions of plant development is drip irrigation, the use of which during irrigation allows the introduction of the necessary nutrients to plants.
The aim of the research was to establish the effect of leaf feeding of plants on the yield of corn for grain. The research method is field experience in a specially designated area to establish differences between the variants of the experience. Field experience provides for exploratory research and quantifies the effect of leaf feeding of corn for an objective justification of the introduction of scientific achievements in agricultural production.. In the experimental variants, leaf feeding of corn plants is provided in the phases "5 leaf tillering", "9 leaf tillering" and "exit into the tube" with the norms of 2 kg/ha, 4 kg/ha and 6 kg/ha in comparison with the control variant without leaf feeding of plants. Leaf feeding of corn with the preparation Kristalon with a norm of 4 kg / ha provides an increase in the yield of corn grain when processing plant leaves by 7.6% compared to the processing standards of 2 kg / ha and by 14.7% compared to the control variant without processing plant leaves. An increase in the rate of leaf feeding of corn leaves to 6 kg / ha does not significantly increase the yield of products. Leaf feeding of corn leaves with a norm of 4 kg / ha is recommended for use in the conditions of the south of Kazakhstan.
