Abstract
Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore during rabi 2003 and kharif 2005 to study the effect of different treatments on weed growth and yield of sorghum in sorghum-based intercropping system under rainfed and irrigated eco-system. Weed density and weed dry weight were lesser under paired row sowing than normal row sowing. The weed control efficiency was higher under paired row sowing at 20 and 40 DAS during both the seasons. Minimum weed dry weight and higher weed control efficiency were recorded under pendimethalin + one hoeing on 40 DAS and two hoeings at 20 and 40 DAS, respectively. Among the intercrops, sorghum + cowpea reduced the weed density, weed dry weight and increased the weed control efficiency and weed smothering efficiency during both the seasons. Normal row and paired row sowing registered significantly higher grain yield during rabi 2003 and kharif 2005, respectively. Two hoeings and pendimethalin + one hoeing produced more grain yield during rabi 2003 and kharif 2005, respectively. Sole sorghum recorded significantly higher grain yield than intercropping system.
