Nitrogen fertilization effect on grain yield and quality of spring triticale varieties

Abstract

The effect of fertilizing three triticale varieties (Timiryazevskya, Karmen, and Ukro) with nitrogen at different rates either one time at pre-sowing (N30, N 60, N90, N 120 and N150) or two times at pre-sowing and flowering stage (N90+ N30) and (N90+ N60) has been studied. The data indicated that all nitrogen treatments applied either at pre-sowing or/ and flowering stage resulted in a significant increase in triticale yield of three varieties (t/ha) compared to control. The highest yield in Timiryazevskya (5.52 t/ha) was obtained after N120+N0 treatment, while in case of Karmen the highest yield (5.19 t/ ha) was obtained with N150+N0 fertilizing, as to Ukro the highest value (5.05 t/ ha) was noticed after N90+N30 treatment. Besides, the values of 1000 grains weight (gm) insignificantly increased in all cases. Protein and gluten percentage points grew simultaneously with increasing nitrogen amount.
