It grows on all soil types. Best in deep, well-drained, alluvial loam with high level of water composition. It can easily adapt to moist environment. If grown in upland areas, sufficient water is needed.
Plow and harrow the field until the soil become loose and friable. In a lowland areas, plow and harrow 4 times. Water the field for 2 days before planting to make the soil soft easy for planting. In upland areas, plow and harrow 3 times before planting. In planting, use pointed metal to make a hole to make it easy.
It can be propagated vegetatively by using corms either whole or in pieces, stem cuttings or even cormels. Traditionally, stem cutting is preferable because it can produce higher yield. During wet season planting is done before the start of rainy season. If irrigation facilities is available, planting can be done whole year round.
The purpose of applying fertilizer to the plants is to keep the rapid development of leaves and to ensure a fast enlargement of corms. Using compost as fertilizer is highly recommended. Mixed it thoroughly during land preparation, 1 to 2 weeks before planting. You can use complete fertilizer (14-14-14), 400 kg in one hectare.
Diseases attack the taro leaves. Use handpicking. Apply commercial insecticides at 6-14 days interval. Use it at the rate of 2 tablespoon every 4 gallon of water. In case of nematode attack, use nematicides you can buy in agricultural supply and fumigate the plants.
Taro can be harvested when most of the leaves turn to yellow color. Maturity of plants in lowland areas is about 8 to 12 months. Taro can mature in upland areas 9 months after planting.
Harvest the plants during dry season. Pulled the corm slowly by the use of hands or tools. Protect the corms for any bruises to avoid rotting. It can be stored in a well-ventilated area where circulation of air can keep it dry to prolong many months of storage.
