Present work was focused on the comparative evaluation of the Taro tuber productivity by using improved cultivation practices versus traditional cultivation practices. Initially, passport data of all the collected 27 cultivars and wild edible aroids were prepared and their Indigenous Collection Numbers (IC) were procured from the Indian Council of Agricultural Research-National Bureau of Plant Genetic Resources, New Delhi. All the collections were phytochemically evaluated and five variants of Colocasia esculenta (L.) H. W. Schott were found to be superior and their IC Numbers are 0631527, 0631529, 0631536, 0631544 and 0631546. Following the randomised block design method for crop productivity evaluation, data of five nutritionally superior cultivar and one check variety were taken in three replications (R1, R2, R3) from eighteen plots of measuring 5×5 m2 (25 m2). Taro tuber productivity in kg/plant from the first and second year’s data from the ICAR-NBPGR, Umiam and also the farmer’s data from Borail Hills Range were analysed by using SPSS software, and that shows significant difference among all the six treatments/variants under Critical Difference at 5% (CD 5%). Total of the data replications (R1+R2+R3) from first, second year data from ICAR-NBPGR, Umiam and also farmer’s data from Borail Hills Range are 18.24 kg, 19.45 kg and 12.69 kg respectively; clearly showing the tuber productivity enhancement of improved cultivation practices over the traditional agro- practices.
