Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 3, Issue 3
Abstract
The results of studies the effects of pre-sowing seed treatment with the preparation Polimiksobakteryn, as well as foliar nutrition with the microfertilizer Micro Mineralis (corn) and the growth biostimulator “Stympo” on the yield of corn hybrids are presented. The studies conducted by us in the conditions of the Right-bank Forest-steppe on the gray forest soils indicate that the yield of corn hybrids of different groups of maturity depended on the hydrothermal conditions of the years of the research and the studied factors, namely the pre-sowing seed treatment with the preparation Polimiksobakteryn, as well as the foliar nutrition with the microfertilizer Micro Mineralis (corn), both individually and in combination with the growth biostimulator “Stympo”. Thus, in 2015-2017, the yield of the middle-ripen corn hybrid Aria varied from 9.60 to 11.01 t/ha on average, while that one of the hybrid Pereyaslavskyi 230 SV from 9.29 to 10.61 t/ha. In 2015-2017 the yield of the middle-ripen corn hybrid Dialoh varied from 10.97 to 12.57 t/ha on average, while the same indicator of the hybrid Flagman ranged from 10.32 to 11.77 t/ha. Consequently, on the basis of our results, the middle-ripen corn hybrids had the highest yield: Aria – 11.01 t/ha, Pereyaslavskyi 230 SV – 10.61 t/ha, Dialoh –12.57 t/ha, Flagman – 11.77 t/ha. It was obtained when using the complex action of pre-sowing seed treatment with the preparation Polimiksobakteryn and foliar nutrition with Micro Mineralis (corn) + “Stympo”, that is more in comparison with the control by 1.41, 1.32, 1.60 and 1.45 t/ha, respectively.
