Abstract
A 2-year field experiment was conducted with wheat (Triticum aesrivum L. emend. Fiori & Paol.) variety HD 2285 in semi-reclaimed sodic soil of Karnal, comprising 4 levels each of nitrogen and irrigation. Scheduling irrigation at 1.2 irrigation water :cumulative pan evaporation (IW :CPE) ratio was better than other irrigation schedules in terms of grain yield. With each increment of N level from 60 to 180 kglha, there was a significant increase in the grain yield as well as N uptake. Response to N of grain production at 1.2 IW :CPE ratio was significantly more than that at 0.6 and 0.9 IW : CPE ratios. The N content in shoot at spike-initiation stage was higher in irrigated than in unirrigated treatment, but reverse was true for N content in grain and straw at maturity. The N uptake through grain and straw was higher whed irrigation was given at 1.2 IW : CPE ratio. Recovery of applied N and N-use efficiency were maximum when imgation was given at 1.2 IW :CPE ratio along with 60 kg Nlha.
