Abstract

Field experiments were conducted to evaluate suitable intercrops and weed management practices for sorghum hased intercropping systems under irrigated condition at killikulam. The results revealed that higher growth and yield parameters, grain and stover yields were recorded in sole sorghum than sorghum intercropped with either blackgram or cowpeu. Pre-emergence application of metolachlor 1.0 kg ha hand hoeing on 40 DAS increased the growth and yield attributes, grain and stover yields of sorghum The interaction between intercropping and weed management practices also revealed that the growth and yield attributes and yields were highest in the intercropping sytem with sorghum + blackgram involving pre-emergence application of metolachlor at 1.0 kg ha one hoeing on 40 DAS.
