Yield performance of taro (Colocasia esculenta (L.)
Schott), has received limited research attention, particularly
under intensive cropping systems needed to meet demands of a
growing population and supply corms for export markets. Four
taro cultivars were evaluated for yield and dry matter
distribution at two locations in Puerto Rico. Averaged across
locations and cultivars, leaves, petioles, roots, corms, and
suckers represented about 3%, 6%, 2%, 37%, and 52%,
respectively, of the total plant dry matter. At both
locations, cultivar Lila showed highest fresh corm yield
(19,533 kg ha-1), corm dry matter yield (6,648 kg ha-1), and
harvest index (0.49) among the cultivars studied. This
formation is valuable for the development of an upland taro
industry.
