Abstract

60 days after planting lowered the weed population and weed biomass and produced significantly higher grain yield (136.5 q ha−1) than other treatments followed by pendimethalin at 1.5 kg ha−1, alachlor 1.5 kg ha−1 and one hand weeding at 60 days after planting. Maximum net return of Rs. 83278 and 76083 was obtained with the integration of pendimethalin at 1.5 kg ha−1 with weeding at 60 days after planting and alachlor at 1.5 kg ha−1 with weeding at 60 days, respectively.
