Abstract

A field experiment was conducted to compare various weed management practices in onion at Dholi farm, Tirhut College of Agriculture, RAU, Dholi, Muzaffarpur, Bihar. The study revealed that effective weed control was recorded under application of Oxyflurofen 23.5EC @ 2ml/L before planting and Quizalofop ethyl 5EC @ 3.5 ml/L at 30 DAT. The treatment Oxyflurofen 23.5EC @ 2ml/L before planting and one hand weeding at 40–60 DAT recorded significantly highest plant height (58.33cm) and number of leaves (9.87) than rest of the treatments. Significantly highest total bulb yield was recorded in Oxyflurofen 23.5EC @ 2ml/L before planting and Quizalofop ethyl 5EC @ 3.5 ml/L at 30 DAT followed by combined spray of Pendimethalin 30EC @ 2.5 ml/L and Quizalofop ethyl 5EC @ 1.75ml/L at the time of planting and at 30 DAT. The result indicated that significantly highest weed population (104.68/m2) was recorded in weedy check plot while Minimum weed population was recorded in the treatment with the application of Oxyflurofen 23.5EC @ 2 ml/L before planting and Quizalofop ethyl 5EC @ 3.5 ml/L at 30 DAT (46.01). The WCE varies from 80.56 to 73.88. Maximum WCE was recorded in Oxyflurofen 23.5EC @ 2ml/L before planting and Quizalofop ethyl 5EC @ 3.5 ml/L at 30 DAT (80.56). The BC ratio estimated in different weed treatment practice over weedy check indicated maximum BC ratio of 2.11 in Oxyflurofen 23.5EC @ 2 ml/L before planting and Quizalofop ethyl 5EC @ 3.5 ml/L at 30 DAT.
