In field trials in the rabi season on black soil at Navalgund, Karnataka, sorghum CSH-8R was grown alone or intercropped with red gram safflower or Bengal gram in 2:1 row ratio and crops were irrigated with 60 mm water at irrigation water (IW):cumulative pan evaporation (CPE) ratios of 0.4, 0.6 or 0.8. Grain yield of sorghum increased with irrigation frequency and was 5.78 t/ha when grown alone and 6.60-6.87 t when intercropped. Grain protein percentage decreased with irrigation frequency and averaged 8.73 when grown alone and 9.00-9.02 when intercropped.
