Abstract
A field experiment was conducted at Water Technology Centre, college farm, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad during rabi 2015-16 to study the effect of different irrigation levels i.e., surface irrigation at 0.6 IW/CPE ratio (T1) , 0.8 IW/CPE ratio (T2) , 1.0 IW/CPE ratio (T3), 1.2 IW/CPE ratio (T4), drip irrigation at 0.6 Epan (T5) , drip irrigation at 0.8 Epan (T6) , drip irrigation at1.0 Epan (T7) and drip irrigation at 1.2 Epan (T8) on the water productivity of maize crop in semiarid tropical climate. The results of the study revealed that the water productivity obtained with 0.6 Epan was highest (1.34 kg m-3) with consumption of 3130 m3 of water, while the lowest was observed in surface irrigation scheduled at 1.0 and 1.2 IW/CPE ratio (0.84 and 0.84 kg m-3) which consumed 4670 and 5170 m3 of water, respectively.
