yam and banana or as intercrop in coconut gardens.
Varieties
Philippines, Madiera, Pusa Baisakhi, NP-24, Co-2, Pusa-8973 (suited to the summer
rice fallows of Onattukara; tolerant to pod borer; duration 66 days)
Seed rate and sowing
Pure crop - 20-25kg/ha
Mixed crop - 6kg/ha
Plough the land 2-3 times thoroughly and remove weeds and stubbles. Channels, 30
