INFLUENCE OF SOWING TIME AND DENSITY OF PLANTING ON THE INDICATORS OF PLANT HEIGHT OF MAIZE HYBRIDS IN THE IRRIGATED CONDITIONS OF THE SOUTH OF UKRAINE

Abstract

Presented is the influence of sowing time and density of planting on the plant height of maize hybrids of various groups of ripeness in irrigation conditions of the southern zone of Ukraine. It’s determined that over the period of the conducted research maize had the maximum indicators of plant height, on average, when it was planted in the third decade of April. Among the groups of ripeness, the plants of the mid-season hybrid Kakhovsky were the highest. Plant crowding from 70 to 90 thousand plants per hectare contributed to the height indicators increase.
