Abstract
Field investigation was conducted on effect of water deficit and plant populations on maize during kharif (2009) season in a split plot design with irrigation as main plot treatments and plant population as sub plot treatments. The irrigation treatments such as normal irrigation water requirement (0.8 IW/CPE ratio) (500 mm) (I1), 75% of irrigation water requirement (0.6 IW/CPE ratio) (375 mm) (I2), 50% of irrigation water requirement (0.4 IW/CPE ratio) (250 mm) (I3), with a normal spacing (60×20 cm) (80,000 plants ha-1) (S1), narrow spacing (30×30 cm) (1,06,666 plants ha-1) (S2) and reduced narrow spacing (45×20 cm) (1,11,111 plants ha-1) (S3) were followed. Higher water productivity was observed in 50% irrigation water requirement followed by 75% of water requirement. Yield increment was registered in narrow spacing than normal spacing. Narrow planting increased the yield by 5%, 6%, 13% over the normal spacing in 50%, 75% and normal water requirement
