A field experiment was conducted during two consecutive Kharif seasons of 2003 & 2004, to find out most suitable weed management practices for different crop establishment methods. Maximum loss of nutrients by weeds was recorded under zero tillage followed by dry seeding under moist condition while highest content of protein in grain and straw was recorded under transplanting. Highest grain yield (54.72q per ha) was also recorded under transplanting which was at par with drum seeding (54.53 q per ha) during first year and significantly superior over other methods during second year. Chemical + 2 hand weeding produced significantly higher grain yield (61.04 q per ha & 60.88 q per ha) over other weed management practices during first and second year, respectively.
