Experiments with wheat WL 410 were conducted on sandy loam soil under rainfed conditions during Rabi 1979-1980 and 1980-1981, using varying number of ploughings in combination with weed control by weedicide and/or interculture. The average grain yield in case of minimum tillage + weed control by weedicide and interculture was better than that obtained by conventional tillage. About 73 per cent reduction in grain yield was observed in case of minimum tillage, when weeds were not controlled. Weed control by interculture was found to be better than the use of weedicide. Net return of Rs. 2035 ha¹ in case of minimum tillage (POWIC) was 40 per cent higher than the conventional tillage.
