Integrated Weed Management in Onion

Pre-emergence application of fluchloralin at 1.0 kg ha−1 supplemented with two hand weedings at 30 and 60 DAT recorded the least weed count and dry matter production favouring the highest yield of onion bulbs (72.4 t ha−1). Fluchloralin, pendimethalin, alachlor, trifluralin and oxyfluorfen at lower doses in combination with one or two hand weedings produced significantly higher yields than their application alone at higher doses.
