Abstract Field experiments were conducted during rabi 2003 and kharif 2005 at Tamil Nadu Agricultural University, Coimbatore to study the effect of different treatments on sorghum based intercropping system under rainfed and irrigated eco-system. Among the different treatments, plant height, leaf area index, dry matter production and earhead weight were increased by paired row sowing than normal row sowing. Sowing and weed management methods had no influence on the growth attributes during rabi 2003 under rainfed condition. Normal row and paired row sowing registered significantly higher grain and stover yield during rabi 2003 and kharif 2005, respectively. The earhead weight, number of grains per earhead and grain and stover yield were significantly higher at two hoeings and pendimethalin+one hoeing on 40 DAS during rabi 2003 and kharif 2005, respectively. Sole sorghum recorded significantly higher growth, yield attributes, grain and stover yield than intercropping system. The sorghum grain equivalent yield and LER were higher under sorghum intercropped with cowpea than other intercropping system.
