Corn hybrids 77MAY35 and 72MAY80 Determination of the irrigation regime

Abstract

Determination of the irrigation regime of corn hybrids 77MAY35 and 72MAY80 was carried out on pilot plots of the village of Dosi in the Caspian region of Sakartbelo. The empirical dependence of the distribution of marginal soil moisture requires monitoring the growth and development of corn hybrids 77MAY35 and 72MAY80, at different stages of the vegetation period, differential determination of the active soil layer depending on moisture and cohesion, clarification of the irrigation regime.

The reason for the economical use of water is the current water crisis in the world with an emphasis on agronomy. Agronomic research gives us the opportunity to correctly and economically use irrigation water, using resource-saving technologies. The corn hybrid 72MAY is used both for selection and for grain, it gives a rich harvest in various soil moisture conditions. The study of agrochemical and physical indicators, chemical and hydrophysical studies, agrotechnical measures, reasonable distribution of irrigation and fertilizing modes allowed to increase the yield of corn hybrids 77 MAY35 and 72 MAY80 by two times.
