| Abstract | The present state of agriculture in Ukraine is characterized by a slight increase of grain products cultivation. The research of S.M. Kalenskaya defined high efficiency of grain production of this crop under the conditions of forest-steppes of Ukraine. Research has established that different time limits of nitrogen fertilizing differently affected on the amount of grain yield of winter rye. Thus, the introduction of 30 – 90 kg / ha of nitrogen fertilizer only at the second stage of plants organogenesis increased the grain yield of winter rye to 3,73 – 4,22 t / ha or to 1,1 – 1,59 t / ha. Transferring of introduction 30 – 60 kg / ha of nitrogen fertilizer in top-dressing at the IV stage of organogenesis ensured grain yield formation at the level of 3,44 – 3,63 t / ha which was more on 0,81 – 1,0 t / ha. The highest grain yield of winter rye at fractional introduction of nitrogen fertilizers was in variant of background + N60(II) + N60 (IV) — 4.69 t / ha, the lowest yield was obtained in the variant of background + N60(II) + N60 (IV) — 4 14 t / ha. In average within three years of study the grain protein content of winter rye in the variant without fertilizers was 8.0% and increased to 8,2 – 8,9% in variants with the introduction of N30 – 90 on thawed soil. In embodiments of the transfer of N30 and N60 in feeding of early exit of plants in the tube, this index was accordingly 8.4% and 8.8%. Yield of protein from grain yield of winter rye ranged from 210 – 436 kg / ha. For single-feed the highest yield of protein formed in the variant of background + N90(II) — 376 kg / ha, but the highest it was at double feeding in a variant of background + N60(II) + N60 (IV) — 436 kg / ha. | ||
