Résumé

La performance en rendement de taro (Colocasia
esculenta (L.) Schott) a recu une attention limitee, en
particulier dans les systemes de culture intensive qui ont
pour but de satisfaire la demande en recolte d'une population
croissante et de fournir des bulbes pour les marches
etrangers.  Quatre varietes de taro ont ete evaluees a deux
endroits differents de Porto Rico pour examiner leur rendement
et leur distribution en matiere seche.  En moyenne, compte
tenu des differences de sites et de varietes, les feuilles,
les tiges, les racines, les bulbes et les surgeons
representent respectivement 3%, 6%, 2%, 37%, et 52% du total
de la matiere seche de la plante.  A chaque endroit, la
variete Lila a donne un rendement plus eleve en bulbes frais
(19,533 kg par hectare), en matiere seche de bulbes (6,648 kg
par hectare), et en indice de recolte (0.49), entre les
varietes etudiees.  Ce renseignement est utile pour le
developpement de l'industrie du taro.

Abstract

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.
