Abstract

The purpose. To study effect of minimization of soil cultivation and different ways of importation of fertilizers upon efficiency of agro-technology of production of grain of corn on irrigated lands of Steppe of Ukraine. Methods. Long-term field experiments, agrochemical analyses of soil and plants, phenological observations over growth and development of plants of corn, harvesting and account of grain yield with statistical analysis of data are carried out. Results. The maximum productivity of grain of corn (on the average for 3 years) was gained at importation of N90P45 with irrigation water in phase of 10–12 leaves and in phase of ejection of brushes — 10,4 t/hectare. Dose of fertilizers N180P90 is better paid for itself by increase of productivity at its importation in 2 times by equal parts in phases of 10–12 leaves and ejection of brushes (on N90P45). Conclusions. Minimization of soil cultivation, importation with irrigation water of means of chemization, use power-saving sowing campaigns, irrigation, harvest and transport equipments of mechanization will enable to lower power inputs on production of grain of corn at irrigation minimum on 35–40 %, having converted in such a way intense energy-dependent technique of growing into power-saving. The opportunity of synchronous optimization of water regime of plants and their security with readily available shapes of nutrients at stages of organogenesis is realized. Application of the developed technique will enable to gain high productivity of grain of corn in conditions of irrigation at optimum overlapping agrotechnical methods and intelligent use of irrigation water, fertilizers, power and material resources.
