Abstract:
Results of the experiment revealed that conventional tillage in maize with integrated application of pre emergence herbicide metribuzin @ 200 g ha^-1 with one hand weeding at 35 DAS in maize proved to be the cost effective option for controlling weeds and enhancing the weed control efficiency. The yield and yield attributing characters like no. of cobs plant^-1, no. of rows cob^-1, grain and stover yield of maize was remarkably enhanced in integrated application of pre emergence herbicide metribuzin @ 200 g ha^-1 with one hand weeding at 35 DAS, which was also found on a par with hand weeding practice at 15 and 35 DAS under conventional tilled maize in kharif season. The same treatments were found economically viable. Unweeded control resulted with highest weed density, dry weight and lowest weed control efficiency thereby reduction in grain yield.
