Fertilizer management in Onion

  • Onion needs a heavy dose of fertilizers for a good yield.
  • Farmyard manure @ 8-10 tonnes/Acre may be incorporated into the soil one month before transplanting.
  • Nitrogen 50 kg/Acre, Phosphorus 25 kg/Acre and Potash 30 kg/Acre.
  • Full amount of P, K and half of N are to be added just before transplanting.
  • Rest of the N is to be given as a second dose at 20-25 days after transplanting, and third dose is given at 45-60 days after transplanting.
  • Zinc sulphate application (Znso4@10 kg/Acre) and Boron 4 Kg/Acre increases yield as well as improves the quality of bulb.
