Abstract
A field experiment was conducted in red sandy loam soils during the rainy season 2000 and 2001 at Regional Research Station, Paiyur, to study weed dynamics, yield and economics in sorghum [Sorghum bicolor (L.) Moench] pulses intercropping system under rainfed condition. The treatments consisted of recommended practice of sorghum (pure crop) with atrazine 0.25 kg a.i./ha and sorghum intercropped with cowpea [Vigna unguiculata (L.) Walp.], blackgram (Phaseolus mungo L.), and greengram (F radiatus L.) without and with pre emergence her bicide metolachlor 1.0 kg a.i./ha. Application of atrazine 0.25 kg a.i./ha in pure crop of sorghum and metolachlor 1.0 kg a.i./ha in intercropping system controlled the weeds effectively compared to no herbicide application. Ap plication of metolachlor increased the mean sorghum grain yield by 54, 48 and 47% and pulses grain yield by 4 , 38 and 27% in sorghum cowpea, sorgtium blackgram and sorghum greengram intercropping, respectively, com pared to no herbicide application. The higher net income (Rs 10,759) and benefit : cost ratio (3.1 6) were recorded in sorghum greengram with metolachlor application than other intercropping system.
