Abstract
An experiment was conducted to study the effect of irrigation and nitrogen on pearl millet during summer 2010 at Anand Agricultural University, Anand. Twelve treatment combinations of four irrigation levels (0.4, 0.6, 0.8 and 1.0 IW: CPE ratio), three levels of nitrogen (80, 120 and 160 kg N ha -1 ) were tested in split plot design with four replications. The result revealed that the frequent irrigations at 1.0 IW : CPE ratio significantly increased the plant height, tillers per meter row length and leaf : stem ratio and produced significantly the highest green forage, dry matter and crude protein yields and registered the highest net returns. However, lower irrigation level of 0.4 IW: CPE ratio was significantly superior in WUE than 1.0 IW : CPE ratio. Successive increase in nitrogen application increased yield attributes, leaf, stem ratio, crude protein content as well as WUE. Application of 160 kg N ha-1 recorded significantly the highest green forage, dry matter and crude protein yields of pearl millet and gave the highest net returns.
