Preparation of the field Ginger needs a well-prepared field where the soils have been dug and softened such that when the crop sprouts, it easily breaks through.
You should dig the holes at least three weeks in advance. The holes should be at least 1 x1 feet.
The holes are that wide because ginger expands as it grows in the ground. A larger hole covered with soft soil makes it easier for this process.
Weeding must be regular. Depending on the presence of weeds, remove them at least twice every week. Weeding is done by hand not hoes.
Hoes destroy the rhizomes.
Fertilisation
Coffee husks are good fertilisers for the ginger crop. Coffee husks help the soil retain the required moisture and fertility. An acre can take about three to six lorries of four tonnes each.
The husks can be applied at least two weeks before planting. They are spread out evenly in the whole field and then covered with soils.
Also, phosphate is good for fertilising; an acre requires a supply of 50kg. These are mixed in the soils at planting.
Planting the crop
Ginger is propagated by dividing the rootstock or rhizomes.
Each can be just 2cm long, but it must have a nodule. Rhizomes can be got from ginger seeds and planted 30cm from each other in drills in the field spaced by 60cm.
Harvesting
Ginger takes between six to eight months to mature. This means that there is one season in a year. Mature crops show yellowing of the leaves and withering.
The top part dries off and falls to the ground. It is advisable to leave the crop unharvested for the first year and it sprouts again and is harvested in the second year ensure high yields.
Harvesting is done by uprooting the whole plant. The yields depend on many factors such as fertility of the soils, supply of rains and others. If all goes well, an acre can produce about two to eight tonnes.
Ginger can be stored for over six months without going bad. It can also be processed into powder for longer shelf lives.
Ginger should be stored in a cool, dry environment with enough aeration, so that it does not attract pests to rot.
Pests and diseases
Root mealy bugs may attack the crops but not cause serious damage.
In other words, ginger is largely resistant to mealy bugs.
For the diseases, a fungal infection arising from excessive use of coffee husks during damp weather causes damage to plants.
