Abstract: A field experiment was conducted during rainy (kharif) season of 2017 in Split Plot Design with three replications at Crop Research Centre of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar. The treatments consisted of four moisture regimes in main plots and four zinc levels in sub plots. The result showed that among the moisture regime treatments, maximum value for no. of panicles/m2 (225.58), grain yield (33.14 q/ha), harvest index (41.30 %), gross return (70193 /ha) was found with I1 which was significantly superior over I3 and I4 but was statistically at par with I2 but maximum value for water productivity (3.51 /m3), net return (34067 /ha) and B: C ratio (0.99) was found with I2 which was significantly superior over I4 but was statistically at par with I1 and I3 except water productivity which was significantly superior over I1 and I4 but was at par with I3. Test weight was not influenced significantly by moisture regime treatments. In context of sub-plot treatments maximum no. of panicles/m2 (223.87), grain yield (32.57 q/ha), harvest index (41.23 %), water productivity (3.46 /m3), gross return (69048 /ha), net return (33464 /ha) and B: C ratio (0.94) was found with Z3 which was significantly superior over Z1 but was statically at par with Z2 and Z4 except gross return which was superior over Z1 and Z4 but statistically at par with Z2. Test weight was not influenced significantly by zinc levels.
