The subject of research is corn for grain of different groups of maturity according to cultivation on two backgrounds of fertilization with the use of microfertilizers and a growth regulator in the conditions of the Western Forest Steppe. The purpose of the work is to improve the elements of the intensive technology of growing corn for grain of modern hybrids of different maturity groups in the conditions of the Western Forest-Steppe of Ukraine. Research methods: The research is based on field experiments using the following methods: counting and weighing - to determine the density of plant stands and parameters of the crop structure and grain yield, physico-chemical - and chemical - to determine the agrochemical parameters of the soil and the protein content in grain, mathematical statistical - to establish the reliability of research results, comparative and calculation - to determine the economic efficiency of the researched elements of technology. It should be noted that for the 2023 research year, corn hybrids responded positively to the calculated rate of N160 P60 K60. We also noted a positive effect on the formation of corn grain yield of hybrids of different maturity groups, little use during the growing season of the drug Vimpel (0.5 l/ha) and microfertilizers Oracle multicomplex (1 l/ha) and Oracle biozinc (1 l/ha), increases grain yields ranged from 0.32-1.50 t/ha. Over the years of research when growing corn for grain of different maturity groups in the conditions of the Western Forest Steppe on dark gray podzolized soil on loess rocks, significant increases in yield (1.82-2.01 t/ha) were provided by DN Galatea hybrids (FAO - 260) and DN Demetra (FAO - 300) compared t Product Description popup.authors Markarian Volodymyr V. popup.nrat_date 2023-12-14 Close
