Abstract

A field experiment was conducted to evaluate the role of intercrops in respect of weed suppression and chemical methods for effective weed control in pigeon pea and green gram based intercropping systems.The aim of this stydy to assess the most suitable weed management practices for pigeonpea + green gram intercropping system.Results revealed that the relative density of dicot weeds was lower than the relative weed density of monocot weeds and did not show any significant effect on weed dynamics of pigeon pea and green gram based intercropping systems whereas, the application of Pendimethelin @ 1.0 kg ai + Imazethapyr @0.1 kg ai/ha significantly minimum weed density, weed dry weight and maximum weed control efficiency recoreded compared to weedy plot at 25, 50 and 75 days after sowing (DAS). This might be due to reduction in weed competition.
