Abstract

Field experiment was conducted on onion to develop efficient integrated weed management practicesunder various levels of nitrogen. Two hand weeding at 20 and 40 DAT or application of pendimethalin (PP) +oxadiargyl at 40 DAT or application of pendimethalin (PP) fb 1 HW at 40 DAT combined with 100 kg N ha−1 were recorded significantly higher bulb weight, bulb yield and net returns. Thus, either of above integrated weedmanagement practice can be used for rabi (winter) season onion in loamy sand soils.
