Abstract

An experiment was conducted at CCS Haryana Agricultural University, Hisar during rabi 2010-11 and 2011-12, consisting of three irrigation frequencies viz. one irrigation at CRI, two irrigations at CRI and heading and four irrigations at CRI, late tillering, heading and milking in main plots and five nitrogen levels (0, 50, 100, 150 and 200 kg N/ha) in sub-plots in strip plot design with four replications. Grain yield and NUE increased significantly with increased irrigation levels. Increase irrigation frequency increased the N (33.4 and 31.3 %), P (42.2 and 42.3 %) and K (26.7 and 25.1 %) uptake over one irrigation during 2010-11 and N (16.0 and 15.9 %), P (19.4 and 20.7 %) and K (11.2 and 13.5 %) during 2011-12. Increased nitrogen dose increased the protein content, hectolitre weight, sedimentation value and grain yield over control. Maximum and minimum nutrient uptake was recorded with 200 and 0 kg N/ha.
