摘要：Onion is one of the most important vegetable in India. However, yields are generally low due to weeds problem which reduce onion yields. In order to evaluate various herbicides for weed control in onion, an experiment was conducted at Agricultural Research Institute, Patna under Bihar Agricultural University, Sabour, Bhagalpur during two consecutive rabi Season 2016-17 and 2017-2018.The experiment comprised 3 herbicides and were applied alone , their combinations ,hand weeded plot and a weedy check was also included. Thus the eight different treatments were: weed free throughout the all crop period, two hand weeding at 20 and 40 days after transplanting, glyphosate at the rate 1kg active ingredient /ha 15 days before transplanting, pendimethalin at the rate 1 kg active ingredient/ha as pre emergence i.e., 3 days after transplanting, oxyfluorfen at the rate 250 g active ingredient /ha as post emergence i.e. 30 days after transplanting, pendimethalin followed by oxyfluorfen, glyphosate followed by pedimethalin followed by oxyfluorfen and the control.
