Field studies were conducted at CCS, Haryana Agricultural University Hisar during winter season of 1990–91 and 1991–92. Trifluralin at 1.5 kg as pre-plant, pendimethalin 1.5 and 1.0 kg/ha as pre-emeraence followed by one band weeding at 25 days stage and hand weeding twice at 25 + 50 days stage proved highly effective against C. album, V. sativa and Fumaria parviflora. Post-emergence application of isoproturon also proved quite effective. Maximum seed yield was obfained in weed free plots followed by hand weeding twice obtained in weed free plots followed by hand weeding twice at 25 + 50 days stage, pendimethalin 1.0 kg + one hand weeding, trifluralin 1.5 kg and pendimethalin 1.5 kg/ha.
