Abstract

  Taro (Colocasia esculenta) is a tropical food crop with high potential, widely adapted to varied agro-climatic conditions. Colocasia contain 3.7 - 3.9, 1.16 - 1.53, 21.7 - 24.4 g/100g of crude protein, crude fibre, carbohydrates, respectively and minerals to an extent of 382 - 1049, 114 - 171, 0.19 - 0.51, 3.24 - 11.72, 3.01 - 5.63, 0.54 - 6.82, 58 - 266, 78 - 96, and 8.4 - 39.6 mg/100g of potassium, phosphorus, copper, iron, zinc, manganese, calcium, magnesium, and sodium, respectively. Presence of fairly good amount of phytochemicals and antioxidants in colocasia had been proven effective in controlling coronary heart diseases, certain cancers and chronic degenerative diseases. Taro leaf silage, petioles, and corms could be used as feed ingredients for rearing of pigs, ducks and poultry.
