Author(s): B. B. SAHOO AND P. TRIPATHY
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.
