A field experiment was conducted in Karnataka, India, during the 2002/03 winter season, to study the dry matter production, yield, water use efficiency and economics of different sorghum cultivars under drought situation in vertisols. The RSLG 262 cultivar (Mouli) recorded a high grain yield (2041 kg/ha) followed by SPV 1591 (1919 kg/ha) and SPV 1546 (1832 kg/ha), due to better plant growth with higher dry matter production in different plant parts and its translocation to the ears at physiological maturity. The cultivars that produced higher dry matter exploited higher moisture in the top 60 cm of the soil profile from 60 days after sowing until harvest resulting in lower soil moisture in the profile. Mouli recorded the highest water use efficiency of 102.10 kg/ha/cm. Higher gross returns (Rs. 15 398/ha), net returns (Rs. 9239/ha) and benefit cost ratio (2.50) were also observed in Mouli.
