FORMATION OF GRAIN PRODUCTIVITY OF MAIZE UNDER DIFFERENT SOIL TILLAGE

Abstract

The results of two-year researches of the impact of different ways of basic soil tillage, common in the zone of insufficient moisture of left-bank forest-steppe, on grain productivity of corn are stated in the article. We found that in growing corn for grain it is reasonable to use soil tillage of 37–40 cm depth at which soil gets optimal agrarian and physical properties. We noticed its deeper moisturizing during spring snowmelt and improved humidity level for culture in the second half of the vegetation season. This helps to optimize the conditions for growth and development of maize plants, especially during the dry summer period.
