Abstract

The article presents results of the studies carried out in a 3-factor field experiment to assess the comparative productivity of grain corn hybrids, methods of plant protection from weeds and the effectiveness of leaf feeding with nitrogen and zinc-containing products. Studies showed that NK Gitago FAO 200 and SI Fenomen FAO 220 hybrids are distinguished by higher productivity. In protecting plants from weeds, the application of herbicides is more effective in comparison with mechanical treatment of corn row spacing, while the yield increased by 0.59 - 1.10 t / ha or 7.9 - 14.7%. Leaf dressing with Isagri Nitrogen at a dose of 2 l / ha at the phase of 3-5 leaves increased the yield by 0.18 t / ha or 2.3%, the variant with Izagri Nitrogen at a dose of 2 l / ha + Izagri Zn at a dose of 1 l / ha - by 0.58 t / ha or 7.4%. Relations between the grain yield and the duration of interfacial periods were established, as well as adic factors and conditions of growth and development of corn plants in agrocenoses (content of productive moisture in the soil, plant density, number and weight of weeds before harvesting).
