THE INFLUENCE OF MINERAL NUTRITION ON THE GROWTH PROCESSES OF CORN PLANTS IN THE CONDITIONS OF THE RIGHT-BANK FOREST-STEPPE

Abstract

The article presents environmental factors that have a direct impact on the growth and development of corn. It was found that this indicator changes depending on the hydrothermal conditions of the year of the study and the maturity group of the studied hybrids. Regardless of the natural water supply, the use of irrigation, nutrients and nutrition, nutrients have the greatest influence on the formation of plant stand density. Irrigation, nutrients, and nutrition have the greatest influence on the formation of plant stand density. When growing agricultural crops, it is important to evaluate growth processes that are influenced by natural and agrotechnical factors and that can be regulated to increase plant productivity. In this regard, it is important to study the impact of basic agrotechnical measures (irrigation regime, doses of nitrogen fertilizers, plant stand density) on the growth, development, production processes and seed productivity of corn. The main results show that corn as a food crop, one of the most productive grain crops, plays an important role in solving the problems of sustainable grain production in the agro-industrial complex of Ukraine. The results of the study of the effect of different forms and rates of nitrogen fertilizers on the dynamics of the height of corn plants in Ukraine are presented. The optimal parameters of mineral fertilizers in feeding corn have been determined. The influence of fertilizer application on the linear dynamics of corn growth in the conditions of the north-east of Ukraine was determined. The optimal parameters for the use of mineral fertilizers in corn fertilization have been determined. The conclusions confirm the importance of using different fertilization systems and basic tillage for the formation of biometric indicators and productivity factors of corn hybrids of different maturity groups.
