PRODUCTIVITY OF MAIZE HYBRIDS IN POLISSIA AND FOREST-STEPPE OF UKRAINE

The article presents the results of research on the productivity of grain and sugar corn hybrids in the Polissia and Forest-Steppe regions of Ukraine. The yield, grain quality and resistance to environmental stress factors of the hybrids were evaluated. It was found that the agroclimatic conditions of these regions significantly affect the productivity of the crop, in particular, its ability to form a stable grain yield and increase the sugar content in the cobs of sugar corn. The onset of phenological phases of development and their influence on yield indicators were studied. The results are useful for improving corn growing technologies and selecting the most productive hybrids for different climatic zones of Ukraine.
