  • The seedlings are ready for planting in 6 - 8 weeks after sowing.


  • The land is prepared to good tilth by ploughing, harrowing and levelling.
  • 15 tonnes of well rotten FYM, 300 kg single superphosphate and 65 kg muriate of potash per hectare are applied basally.
  • The seedlings taken old from the nursery are planted in the ain field with a spacing of 15 or 30 cm between thje rows and 15 cm or 7.5 cm between the plants (444444 plants/hectare) in December.
  • The field is irrigated on alternate days until plants establish, thereafter the crop is irrigated at 5 - 7 day intervals during non-rainy periods.

Interculture - Fertilizers

  • The field is kept free of weds during the initial stages of crop establishement and frowth and after first harvest by manual weeding.
