Satanovska I. Formation of productivity of corn hybrids of different maturity groups on silage depending on a fertilizer in conditions of the Forest-steppe right-bank

The processes of growth, development and yield formation of green mass of corn hybrids of different maturity groups depending on seed treatment, foliar feeding and doses of nitrogen fertilizer. The aim of the research was to identify the dependence of formation of aft productivity of corn hybrids from different maturity groups of pre-sowing seed treatment and fertilizer system in conditions of the Forest steppe right-bank. Methods - visual, weight, physiological, laboratory, statistical, comparative. The results - in the work set out the features of growth, development and the formation of photosynthetic, individual and aft productivity in corn hybrids of different maturity groups, depending on the effect of seed treatment, foliar feeding and the use of different doses of nitrogen fertilizer in conditions of the Forest steppe right-bank. Installed the variability of the indicators and quality compound of green mass of hybrids of different maturity groups depending on the models of technology of growing. Give the economic and bio-energetic evaluation technology of growing corn on silage of hybrids of corn different maturity groups and assessment of the elements of technology on competitiveness. Introduced - in agricultural farms of Vinnytsia region over an area 185.7 hectares. Industry - Agriculture.
