The effect of foliar feeding with microelement chelates on the yield of spring wheat when cultivated on meadow-black soil

The aim of the research was to investigate the effect of foliar feeding of zinc and copper chelates in tillering phase on the yield and quality of foliar feeding the spring wheat harvest under the conditions of the southern forest steppes of the Omsk Irtysh region. The results of the experiments on the use of zinc and copper chelates in the cultivation of common wheat - in memory of Aziev - in the southern forest steppe of Omsk Irtysh region by the method of foliar feeding were presented. In field experiment in the fields of Omsk Research Center carried out in 2017-2019 zinc chelates were used in the dose of active ingredient of 10 g/hectare, 20, 30 g/hectare, and copper chelates also in the same dose. The formation of spring wheat crop changes with the use of chelates made of zinc and copper, which increased the yield from 0.10 to 0.23 t/hectare of grain. The protein collection using chelates increased from 295 in the control to 322 to 344 kg/hectare, the germination energy of obtained seeds increased from 93.3 in the control to 94.8 to 98.0 % of the foliar feeding in the tillering phase. The best mass of 1000 grains (32.45) and grain type (717 g/l) was Cu10, exceeding the control indicators (29.92 g and 693 g/l). The gluten content was 27.03-28.03 % (with IDC of 56.0-61.0 units), in the best yield variants (Zn20 and Cu10) was at a maximum level of 27.66 and 27.60 %. The best doses of zinc and copper for foliar feeding in the tillering phase were 20 g/hectare (yield increase of 0.20 t/hectare, in control of 2.20 t/hectare) and 10 g/ hectare (0.20 t/ hectare). Positive effect of micronutrient fertilizers on the protein content in grain and laboratory germination of the obtained seeds was demonstrated.
