Abstract:
A field experiment was conducted during the rabi season of 2015-16 (November, 2015 to April, 2016 at Research Farm of Chaudhary Charan Singh, Haryana Agricultural University, Hisar. Treatment combinations comprising four wheat varieties (KRL 210, WH 1105, HD 3086 and DBW 88) in the main plot and five nitrogen levels (0, 50, 100, 150 and 200 kg N ha^-1) in sub-plots were tested in a split-plot design with 3 replications. Results revealed that the grain yield and N uptake (grain and straw) were significantly higher in the variety WH 1105. However, N content in grain (2.08%) and straw (0.38 %) were significantly higher in DBW 88 as compared to other varieties. The incremental N levels significantly increased grain yield. Whereas, the N content and its uptake by grain and straw were also recorded higher up to 150 kg N ha^-1 but was at par with 200 kg N ha^-1. The economic optimum dose of nitrogen for wheat varieties KRL 210, WH 1105, HD 3086 and DBW 88 were 182.4, 188.4, 185.9 and 181.2 kg N ha^-1 and the agronomic optimum dose was 188.8, 194.1, 192.6, and 186.6, respectively. However, on the mean basis for wheat varieties, the economic optimum dose and agronomic optimum dose were worked out to be 184.3 and 192.6 kg ha^-1, respectively. On the basis of 1year results, it may be suggested that wheat variety WH 1105 should be grown with 188.4 kg N ha^-1 under saline water irrigation conditions.
