also be grown as a mixed crop with tapioca, colocasia,
yam, and banana or as an intercrop in coconut gardens.
Philippines, Madiera, Pusa Baisakhi, NP-24,
Co-2, Pusa-8973 (Pusa-8973 is suited to the summer rice
fallows of Onattukara; tolerant to pod borer; duration
66 days).
Seed rate
Pure crop 20-25 kg/ha
Mixed crop 6 kg/ha
Sowing
Plough the land 2-3 times thoroughly and remove weeds
and stubbles. Channels, 30 cm broad and 15 cm deep,
are drawn at 2 m apart to drain off excess rainwater
during kharif season and provide irrigation during summer
season. The seeds may be sown broadcast.
For rainy season crop, drainage is very
important.No irrigation should be given when the crop
is in the full bloom stage.
Manuring
FYM 20 t/ha (as basal)
Lime 250 kg/ha or dolomite 400 kg/ha
N 20 kg/ha
P2O5 30 kg/ha
K2O 30 kg/ha
Lime may be applied at the time of first
ploughing. Half the quantity of N and the full quantity
of P2O5 and K2O may be applied at the time of last ploughing.
The remaining quantity of N (10 kg) can be applied as
foliar spray of 2% urea solution in two equal doses
on the 15th and 30th day after sowing.
Two weeding should be given to keep the
field free of harmful weeds, first 20-25 days after sowing
and second 45 days after sowing.
Apply carbaryl 0.15% suspension, if pests
are observed in serious proportions.
Shattering of pods is a great problem.
Pick the pods as soon as they mature.
1.2-1.5 tons of grains per hectare.
