The field experiment was conducted at Instructional farm of A.N.D University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi, 2016-17. The treatments was comprised with five levels of irrigation viz. CRI stage (I1), 0.6 IW/CPE ratio (I2), 0.8 IW/CPE ratio (I3), 1.0 IW/CPE ratio (I4), and 1.2 IW/CPE ratio (I5) in Randomize Block Design with four replications. The results reaveled that the highest fresh and dry weight and density of root, grain and straw yield by crop were recorded with 1.0 IW/CPE ratio (I4) moisture regime followed by 1.2 IW/CPE ratio (I5) and minimum with CRI stage (I1), 0.6 IW/CPE ratio. The maximum reduction in pH and EC and buildup in organic carbon were recorded of (I4) 1.0 IW/CPE ratio (6 irrigations). The maximum moisture extraction was noticed in the upper most soil layer i.e. 0-20 cm followed by 20-40 and 40-60 cm depth. Increasing levels of moisture regimes from CRI stage (I1) to 1.2 IW/CPE ratio (I5) increased the moisture extraction. The increment in extraction of soil moisture and consumptive use of water and reduction in water use efficiency were recorded with the increasing moisture regimes from CRI stage (I1) to 1.2 IW/CPE ratio (I5). The maximum water use efficiency of (166.6 kg ha-1cm-1) was obtained under moisture regime at CRI stage (I1) followed by irrigation at 0.6 IW/CPE (I2). The lowest water use efficiency (71.7 kg ha-1cm-1) was recorded under moisture regime at 1.2 IW/CPE ratio (I5).
