An experiment was conducted at Nadia, West Bengal during 2012 and 2013 to evaluate the effect of herbicides for weed control in transplanted chilli. The weed density, dry weed biomass, WCE and yield components of chillies such as number of fruits/plant, fruit length and economic yield were significantly affected in response to weed control treatments. Treatment receiving oxyfluorfen recorded lower weed biomass (6.01 and 17.57 g/m2) and higher WCE (81.7% and 75.0%) at 30 and 60 DAT, while hand weeding recorded the lowest weed biomass (4.87 and 17.32 g/m2) and highest WCE (85.5 and 75.4%). Hand weeding resulted in the highest number of fruits/plant (36.11), fruit length (6.75 cm) and yield of chilli (3.46 t/ha).
