Issue №: 3 (34)
The issue of the journal is dedicated to the study of optimization of elements of crop cultivation technology. An important role is given to the influence of legumes on improving soil fertility, adaptive selection, mineral and foliar fertilization of crops, ecology and environmental protection, in particular, the influence of chemicalization on soil and grain pollution by pesticides, and methods of combating harmful objects.

The article presents the results of experimental studies of the features of the formation of elements of grain productivity of corn hybrids of different maturity groups depending on the density of plants and fertilization, taking into account new forms, clarification of application rates and terms of their application according to the stages of organogenesis. The share of influence on corn productivity of plant density was the highest and amounted to 72.7%. The share of the influence of hybrid characteristics was smaller - 10.84%, the share of the influence of fertilizer - 10.16% was noted almost at the same level. A high index was noted for the share of the influence of the interaction of plant density and fertilizer - 5.98%, respectively. The maximum indicators of the elements of the crop structure (the number of grains from the cob and the mass of grain from the cob) were noted on the variant with the simultaneous application of zinc sulfate, Ecoline Zinc and Ecoline Boron on the background of N100P31 at a density of 60 thousand plants/ha in hybrids of corn DKS 3795 - 501.7 pcs. and 164.9 g; DKS 3972 –569.8 pcs.; 187 g; and DKS 4351 – 580.3; 182.8 g. This is higher compared to the control variantby 130.9 pcs., 66.5 g; 154.5 pcs., 77.1 g; 190.9 pcs., 75.3 g, respectively. For increasing the density to 70,000 plants/ha, there is a decrease in the elements of the crop structure, both the number of grains from the cob and the weight of the grain from the cob: DKS 3795 – 465.5 pcs., and 149.8 g; DKS 3972 – 517.4 pcs. and 165.1 g; DKS 4351 – 549.3; 156.7 g; The maximum decrease in the elements of the crop structure was noted in this variant at a density of 80,000 plants/ha: DKS 3795 –427.8 pcs., 131 g; DKS 3972 – 502.0; 145.2 g; DKS 4351 – 513.5; 128.6 g, respectively.Themaximum indicators of the elements of the crop structure (the number of ears per plant and the yield of grain from the ear) were noted on the variant with the simultaneous application of zinc sulfate, Ecoline Zinc and Ecoline Boron on the background of N100P31 at a density of 60 thousand plants/ha in corn hybrids: DKS 3795 – 1, 2; 85.5%; DKS 3972 – 1.3; 86.4%; and DKS 4351 – 1.3 units, 86.2%, respectively.
