About the Crop
Amorphophallus(Amorphophallus paeoniifolius) requires fairly long growing
season and a rainfall of about 150 cm during the crop period. A well-drained soil
of medium texture is suited for this crop.
Corm pieces are normally planted during February-March, before the onset of monsoon.
Sree Padma: The crop matures
in 8-9 months. Cooked tubers are free from acridity.
Sree Athira: First genetically
improved variety with very good.
Preparation of land
Dig pits of 60 x 60 x 45 cm size 90 cm apart. Collect the topsoil to a depth of
15-20 cm separately and fill it after the pits are formed. Apply cowdung or compost
at 2-2.5 kg/pit and mix with topsoil.
Seeds and sowing
Tuber cut-pieces weighing about 1 kg are ideal for planting. Dip the pieces in cowdung
slurry and allow to dry under shade before planting. After planting, cover the pit
with dried leaves or other mulching materials. About 12,000 cut pieces weighing
about 12 t are required for planting one hectare. Most of the seed material will
germinate within one month after planting. Mealy bugs usually attack the corm in
field and store. Avoid planting corms already infested.
Planting of minisett transplant and cormels gives better yield than traditional
method. Cormels weighing 75-100 g each can be planted directly in nursery beds at
a spacing of 90 x 30 cm.
Apply full dose of P2O5 and half the dose N and K2O
(N:P2O5:K2O @ 50:50:75 kg/ha) after forty five
days of planting along with intercultivation and weeding. Apply second dose of fertilizers
(N and K2O @ 50:75 kg/ha) one month after the first application along
with intercultivation and earthing up.
The crop will be ready for harvest 8-9 months after planting.
