Abstract

The experiment involved nine treatments replicated thrice in randomized block design. Significantly lower density and dry matter of weeds were recorded with weed free followed by oxyflurofen 0.30 kg/ha before planting fb one hand weeding of 40–60 DATS after transplanting and combined application of oxyflurofen at 0.30 kg/ha before planting + quizalofop-p-ethyl 0.05 kg/ha at 30 days after transplanting. The average bulb weight, plant height, marketable bulb and total bulb yield were also highest in weed free while it was at par to oxyflurofen at 0.30 kg/ha before planting fb one hand weeding of 40–60 days after transplanting and oxyflurofen at 0.30 kg/ha + quizalofop-p-ethyl 0.05 kg/ha at before planting and 30 days after transplanting. The maximum B: C ratio of 2.31 was obtained in combined spray of oxyflorfen and quizalofop-p-ethyl at before planting and 30 days after transplanting of crop.
