Abstract: The present investigation was conducted during 2018-19 at the Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, India. The experiment was carried out in Randomized Block Design with 10 treatments and 3 replications. The treatments consisted of T1 (Weedy check), T2 (Weed free), T3(One Hand weeding at 25 DAT), T4 (Paddy straw mulch @ 5 t ha-1), T5 (Oxyfluorfen @ 0.8 kg ha-1 (PE)), T6 (Pendimethalin @ 1 kg ha-1 (PE)), T7 (Oxyfluorfen @ 0.8 kg ha-1+ Paddy straw mulch @ 5 t ha-1), T8 (Oxyfluorfen @ 0.8 kg ha-1 + 2 Hand weedings at 25 DAT and 50 DAT), T9 (Pendimethalin @ 1 kg ha-1 +Paddy straw mulch @ 5 t ha-1),T10 (Pendimethalin @ 1 kg ha-1 + 2 Hand weedings at 25 DAT and 50 DAT).Observations were recorded on the basis of weed parameters and yield parameters. Minimum weed density (weeds mÉ2), weed dry weight (g mÉ2), weed index and maximum weed control efficiency (%) was recorded in T2 (weed free). Maximum yield contributing attributes were listed in treatment T2 (weed free) which was followed by T7 (Oxyfluorfen @ 0.8 kg ha-1 + Paddy straw mulch @ 5 t ha-1).
