 ABSTRACT

Taro (Colocasia esculenta L. Schott) is one of the most important tuber crops extensively grown in North Eastern States. The corm and cormels are the major economic part however, the leaves, flowers and petioles are also used as food by the inhabitants of Arunachal Pradesh. Taro does have the potential to become a significant commercial tuber crops due to the wide range of food items can be prepared from it. In Taro cultivation planting material is a problem. Corms and cormels are used as planting materials and its size and weight plays a vital role on production of taro. To investigate the effect of size of corm on the growth and yield of the taro a field experiments were conducted during 2016 and 2017 at demonstration cum experimental farm of KVK Tirap, Arunachal Pradesh with 8 treatments and 3 replications under randomized block design by using ‘Kani kachu’ cultivar. Plant growth parameters and yields were found to be increased with increased in seed size. Seed cormels weighing 30g was found to be economic planting material of taro resulting in higher net return with highest benefit cost ratio of 2.12. Bigger size seed cormels weighing in 40g, 50g, 60g, 70g and 80g were not desirable owing to higher cost of seed cormel resulting uneconomical yield.

Key words: Taro, Corms, Growth, Yield and Economics
