Efficiency of the use of the complex biological preparation "Megavrozhai" on the formation of the yield and quality indicators of winter wheat grain

Abstract

It was established that foliar fertilization had a significant effect on the formation of elements of the crop structure. Thus, the highest indicator was formed with complex fertilization with nitrogen fertilizers and the biological preparation MehaVrozhai, namely, the number of grains from an ear was 32 ,6 and 29,4 pcs., the weight of grains from an ear was 1,0 and 1,3 g, and the weight of 1000 grains was formed at the level of 42,4 g. Also, it has already been established that a higher level of yield is formed when sowing winter wheat on cereal precursors than when sowing on sunflower, and the highest level of yield is formed when complex foliar fertilizing with nitrogen fertilizers and the biological preparation MehaVrozhai at the level of 4 ,2 and 4,3 t/ha, which is 1,1 and 1,3 t/ha more than in the control when sowing on different predecessors. The analysis of the conducted studies indicates a significant effect of the investigated factors, namely, the highest level of protein and a high increase in glut en content was observed when sowing winter wheat on a grain precursor and when feeding with a complex of fertilizers Urea -ammonia mix-32 + MehaVrozhai. Protein content increased by 6,3 %, and crude gluten increased by 15,6 %
