The effect of nitrogen fertilizer application time on the yield, quality and fractional composition of winter wheat grain after different precursors under conditions of the southern steppe of Ukraine
Keywords:winter wheat, feeding, carbamide, quality, yield, protein, gluten fraction, correlation
The results of application of foliar fertilizing of winter wheat of different norms of nitrogen fertilizers grown after predecessors black fallow, peas and winter oilseed rape and their effect on the yield, quality, and fractional composition of the grain itself are presented. There were determined the optimal rate and timing of application of mineral nitrogen depending on the predecessor and areas of production: food grains or seeds. It is shown that the spring term feeding has a little impact on the grain quality when wheat is grown on the black fallow and peas; the predecessor of winter rape feeding should be carried out in the phase of mass tubing
