PRODUCTIVITY OF CORN AND SILAGE HYBRIDS OF MAIZE IN THE CONDITIONS OF POLISSYA

Abstract

Maize is one of the strategic crops in the world grain production. Increasing the yield of this crop is facilitated by the use of hybrids with high plasticity to agroclimatic growing conditions. The purpose of the research was to evaluate the productivity of corn and silage maize hybrids under growing conditions in the Polissya region. The following methods were used in the research: analysis – in the study of cause and effect relationships of the processes under study; comparison – for detailed analysis of experimental data; synthesis – in the generalization of research results, formulation of conclusions; field – laying of research sites, accounting; statistical – when processing the received data and determining their accuracy. In the article the yield indicators of maize hybrids of grain use, mid-ripe group with semi-toothlike (EXRM 014, EXRN 003, EXRM 021) and toothlike (EXRN 002, EXRM 013, EXRM 015) grain type, and silage hybrids of medium-ripening (S 3825, S 3909) and mid-late groups (S 4210) with toothed (S 4210) and semi-toothed (S 3825, S 3909) grain. In terms of growth energy, temperature and humidity, the studied corn and silage hybrids of maize correspond to the soil and climatic conditions of the Polissya region. Hybrids were evaluated by the average number of rows in a cob, the average number of grains in a row, the average number of grains in a cob, weight 1000 seeds, and yield. When grown in Polissya conditions, the best performance indicators were characterized by grain middle-ripening semi-toothy hybrid EXPM 021, grain tooth-like hybrid EXPM 015 and silo middle-late tooth-shaped hybrid S 4210. Further studies will be aimed at assessing the resilience of these hybrids to the most common diseases in the agro-ecological conditions of the Polissya area.
