FORMATION OF WINTER WHEAT CROP DEPENDS ON FERTILIZER AND EXTRA-ROOT NUTRITION

We have analyzed the influence of different rates of mineral fertilizers and liquid organo-mineral fertilizer AminoQuelant K on the growth of the number of grains in an ear, the weight of one ear of grain, the weight of 1000 grains and the productivity of winter wheat of the Statna variety. The introduction of liquid organo-mineral fertilizer AminoQuelant K took place twice during the growing season of winter wheat foliarly, the first - in the phase of emergence into the tube, the second - after fourteen days. AminoQuelant K is a liquid organo-mineral fertilizer, which was applied at a consumption rate of 2.0 l/ha. The experiment was carried out on the basis of Polis National University and PSP "Ukraine". The research field of Polis National University is located in the Chernyakhiv district near the village of Velika Gorbasha. PSP "Ukraine" is located in the Zhytomyr region, the village of Pochuyki, Zhytomyr district. The experiment was carried out against the background of biological control, mineral fertilization systems - N30P20K50, N60P50K80, N70P60K90 with foliar application of liquid organo-mineral fertilizer AminoQuelant K. In the course of research, it was established that the number of grains in an ear was the largest in the AminoQuelant K feeding option with the addition of N70P60K90, which was 22.9 units, with this fertilizer option, the highest weight of grain from an ear was obtained, which was 1.16 g and the weight of 1000 grains - 45.9 g. The yield was the highest for the 3 fertilizer options – N60P50K80 + AminoQuelant K, which amounted to 4.29 t/ha.
