    • CO 1, CO 2, Chotti Chauli, Badi Chauli, CO 3, CO 4,CO- 5 Pusa Kirti, Pusa Kiran, Pusa Lal Chaulai,
    Isolation Requirement
    • A minimum isolation distance of 400 meters and 200 meters for foundation seed and certified seed class respectively is required.
    Season

    Seed rate

    • At the time of sowing there should be enough moisture in the field for proper germination.
    Manuring
    • Generally the crop is grown on residual fertility of the previous crop.
    • However when manured, 20 25 tons of FYM per ha may be applied at the time of land preparation.
    • Later on 100 kg Ammonium sulphate per ha may be top dressed between rows just before irrigation.
    Irrigation
    • Irrigation is given once in a week. Flowering and seed filling are the critical stages of irrigation.
    Roguing
    • A minimum of two inspections during vegetative stage followed by flowering stage is to be carried out.
