Abstract
Field experiments conducted consecutively for four years (2002-2005) during kharif at OUAT Research Farm in upland condition revealed that recommended practice (butachlor 1.0 kg/ha + HW at 25 DAS) produced significantly higher grain and straw yield of 3767 and 4980 kg/ha, respectively. The same treatment also registered higher net return of Rs. 8070/ha with B:C ratio of 1.55. Population of grasses, broad leaf and sedges were lowest at 60 DAS where recommended practice (butachlor 1.0 kg/ha along with one hand weeding at 25 DAS) was followed. Weed control efficiency was found to be maximum (86.2%) in farmer’s practice (HW at 25 and 45 DAS) at 60 DAS.
