The Effect of Liquid Complex Macroand Microfertilizers on Grain Yield
The study results of the effect of new forms of liquid fertilizers on the yield and structure of grain crops are presented. It was found that the use of preparations “Kodima” and “Kodima NPK” has a positive effect on the growth and development of oats and winter rye. The application of “Kodima” at the rate of 0.3 l/ha as foliar fertilizing results in maximum oats yield of 38.3-38.6 t/ha, both with and without adhesive. “Kodima NPK” is the most effective in pre-sowing seed treatment at the rate of 0.5 l/t, both with and without NPK as background fertilizers. The yield of winter rye increased by 3.1-5.2%. The optimal dose of this preparation as foliar fertilizing is 1 l/ha. The maximum yield of winter rye of 40.2-40.7 kg/ha in the experience on the background of NPK was obtained with the seed treatment (0.5-1.0 l/ha) and foliar fertilizing (2.0 l/t). The best variant without fertilizers was pre-sowing seeds treatment of 1.0 l/t and foliar fertilizing of 1.0 l/ha.
