Tubers of Coocasia
Side tubers are used for planting. Select side tubers weighing 25-35 grams for planting. Make ridges 60cm apart. Plant the side corms at a spacing of 45cm on ridges. Cattle manure or compost may be used as basal manure while planting. It can be applied in holes on ridges before planting. Soon after planting the ridges may be covered with dry leaves or other mulching materials. It prevents loss of moisture and growth of weeds.
Weeding and earthing up is necessary for Colocasia at 30-45 days and 60-75 days after planting. Some vermin compost or other organic manure can be used at the time of first earthing up for better yield. The leafy parts may be smothered about one month before harvest so as to enhance tuber development.

No major pests or diseases for Colocasia.

Colocasia becomes ready for harvest five to six months after planting. Side tubers are separated from mother corms and used.
