An experiment was conducted to study the efficiency of various weed management practices in wheat at Plant Physiology Section, Agricultural Research Institute, Tandojam. The results revealed that broad leaved weeds were predominantly present in the experimental area. The weed species like Chenopodium album and Convolvulus arvensis had maximum intensity of 31.98 and 31.02%, respectively. Weeds were controlled in all the treatments except planting patterns where weed population was increased but biomass was decreased as compared to weedy check. Results indicated that the treatments had highly significant effects on plant height, tillers m-2 grain weight and grain yield, whereas number of grains were significantly affected by, different weed management practices. Buctril-M alone gave the maximum increase in all the parameters studied. Whereas skip row sowing gave the minimum increase. The highest (85.47%) weed control was recorded under hand weeding for full season and it was statistically at par with Buctril-M 40 EC alone and its combination with different planting geometries. Consequently the top scorers out yielded rest of the treatments included in the studies. The response of different planting geometries alone was not very promising, however.
