Abstract
plant fertilization system, which accounts for up to 40%. Domestic and foreign scientists studied the effectiveness of corn fertilization in various edaphic and hydrothermal conditions, namely the use of both the main and foliar application of both mineral fertilizers and microfertilizers. However, these studies must be optimized taking into account new forms, application rates and terms of their application according to the stages of organogenesis and maturity groups of corn hybrids and their biological requirements. The linear measurements of the height of the plants and the attachment of the cob of the hybrids depend, first of all, on fertilization and the density of the plants, as well as genotypic features. By increasing the density of plants, the highest indicators of plant height and cob attachment were obtained. The maximum indicators of plant height and cob attachment, as well as their ratio, were noted on the variant with the simultaneous application of zinc sulfate, Ecoline Zinc and Ecoline Boron on the background of N100P31 at a plant density of 80 thousand r/ha: DKS 3795 – 234; 105 cm; 0.45; DKS 3972 – 247; 114 cm; 0.46 and DKS 4351 – 253; 116 cm; 0.46. This is higher compared to the control variant by 21.0, 13.0 and 0.02 in the hybrid DKS 3795; 23.0, 13.0 and 0.01 in the hybrid DKS 3972; 16.0; 12.0 and 0.02 in the hybrid DKS 4351. The maximum yield was noted on the variant of the experiment with the simultaneous application of zinc sulfate, Ecoline Zinc and Ecoline Boron on the background of N100P31 with a density of 70 thousand.plants/ha in hybrids: DKS 3795 – 9.7; DKS 3972 – 10.8 t/ha. This is higher than the control variant by 4.3; 5.0 t/ha. The highest level of productivity was noted in the hybrid DKS 4351 - 10.2 t/ha, noted for the density of 80,000 plants/ha in hybrids. This is higher than on the control variant by 4.4 t/ha.
