Manures fertilizers and weeding

Planting bulbs:  Manures and fertilizers: FYM: 30 t/ha and N:P:K @ 125:75:125 kg/ha
Weed control: Onion is closely planted crop, which makes the manual weeding difficult. Chemical weedicides have been profitably used for the control of weeds. Basalin 1 litre a.i. per hectare as pre-emergent weedicide before transplanting found effective. Besides this a combination of chloraxuron (trade name: Tenoran) and nitrofen (Trade name ToK-E-25) at 1.0 + 1.0kg a.i. per ha. Applied is post-emergent to weeds, one week after transplanting of onion seedlings controlled most of the weeds.
