Manures and Fertilizers

• Cassava is a heavy feeder and crop is to be adequately manured for getting high yield.
• Apply 125 tonnes of farmyard manure / ha as basal dose. For high yielding varieties, a fertilizer dose of 50 kg N, 50 kg P2O5 and 50 kg K2O / ha is recommended at the time of land preparation.
• If planting of sets is done during hot condition, basal dose of fertilizers and manures may be postponed to one month after planting.
• This will avoid attack of termites and drying up of sets.
• Apply second dose of fertilizer i.e., 50 kg N and 50 kg K2O, 45-50 days after planting along with weeding and earthing up.
• In short duration varieties, fertilizer dose can be reduced to 75:50:75 kg NPK/ha.
