Abstract: Field experiment was conducted to compare different weed control methods in onion during rabi 2010-11 to 2011-12. The experiment was laid out in Randomized Block Design with eight treatments and replicated thrice. The pooled results revealed that significantly highest marketable yield (187.17 q ha^-1) as well as total bulb yield (217.48 q ha^-1) was produced by the application of oxyfluorfen 23.5% EC@2 ml l^-1 before planting and one hand weeding at 40-60 days after transplanting (DAT) than rest of the treatments. The Weed Control Efficiency was significantly highest in T₆ (74.28) than the rest of the treatments. Thus, application of oxyfluorfen 23.5% EC@2 ml l^-1 before planting and one hand weeding at 40-60 DAT or combined spray of pendimethalin 30% EC@2.5 ml l^-1 and quizalofop ethyl 5% EC1.75 ml l^-1 at the time of planting and at 30 DAT reduces the weed infestations with higher bulb yield in onion.
