2. Planting and germination
Seeds can be planted directly in the field or in the nursery to raise seedlings.
Nursery planting: plants seeds in well prepared seedbeds, pots or polythene bags.
Planting seeds directly in the field: generally practised in homestead
plantation.
Plant 2–3 cm deep into the soil and press
lightly.
Keep soil moist but not saturated.
Prepare pits of 1 x 1 x 1 m about 2–4 weeks before planting.
Mix the pit soil thoroughly with 10–20 kg well-rotted organic
matter.
Fertilizers, particularly Triple Super Phosphate (500 g) and
Mauriate of Potash (250 g), can be used in the top 10 cm soil
of each pit.
Plant 2–3 seeds at the centre of each pit, 20–30 cm apart and
2–3 cm deep.
Press soil lightly, water, and then cover with mulch.
Sowing depth
When watering, make sure that the upper rim of the polythene bag is not folded
towards the plant, leading to pools of water.
2 to 3 seeds/hole
2–3 cm
Water pits regularly so soil is moist but not saturated e.g.
every 2–3 days.
Put a fence around the area or each pit to protect seeds
and seedlings from stray animals.
With good moisture and temperature, germination
may start at or around 15 days after planting and
be completed in 25 days.
First weeks after germination
Waterlogging may cause
rotting of seeds and
emerging seedlings.
Young plants must be kept free from weeds.

Remove all plants after
emergence except for one.
