Зернова продуктивність кукурудзи різних груп стиглості залежно від позaкореневих підживлень в умовах лісостепу західного

Abstract

The article presents the results of research on the impact of various foliar fertilizers on the formation of grain productivity of maize in the Western Forest-Steppe. The research has established the best parameters for the use of fertilizers for foliar application in maize cultivation technologies. It was found that among the corn hybrids studied, the highest yield was recorded by RAGT Reakksion from FAO 320. According to the results of research in 2023, its grain productivity was 10.79 t/ha in terms of basic moisture content 14 %. A slightly lower yield was observed in the RAGT Zanetikks hybrid (FAO 340) – 10.73 t/ha. The dependence of harvesting grain moisture content on the ripeness group of the studied hybrid crop was proved. The highest moisture content was recorded in the hybrids RAGT Zanetikks (FAO 340) – 24.8 % and RAGT Reakksion (FAO 320) – 24.3 %. At the same time, it was the lowest in the hybrid RAGT Alikks (FAO 220) – 21.7 %. Among the options for foliar application of microfertilisers, the most effective was the use of YaraVita Gramitrel and Vuksal Grain. Depending on the maize hybrid, the grain yield in these experimental variants was 9.56-11.01 and 9.80-11.12 t/ha, respectively. The harvesting moisture content of the grown products was determined by the biological characteristics of the studied hybrid, while foliar fertilisation had almost no effect on this indicator
