Propagation techniques for rapid establishment and production of cocoyam (Xanthosoma sagittifolium (L.) schott)

Abstract

© 2019, International Society for Southeast Asian Agricultural Sciences. All rights reserved. Corm, cormel and corm setts of cocoyam (Xanthosoma sagittifolium L. Schott) were tested to determine the most practical and efficient propagation technique for its multiplication. The study for evaluating corm and cormel used whole corm, top half, bottom half, and cormel. Corms and its parts showed that all planting materials have comparable sprouting percentage at 8 weeks after planting (WAP) except for cormel which had significantly lower sprouting. Whole corm and top half of corm produced significantly longer corm and higher corm yield than other treatments. The study for sett used small sett with 15 and 30 cm petiole, big sett with 15 and 30 cm petiole and small sett with intact shoots. The result showed that all treatments gave comparable percent survival at 4 WAP except for small corms with intact shoots. Big sett with 30 cm petiole showed higher plant height, stem girth, petiole length, and number of leaves than other treatments. Small setts with 15 and 30 cm petiole and big sett with 30 cm petioles have comparable corm length, girth and yield. All treatments except for those with small setts with intact shoots have comparable number and length of cormel. Cormel yield from small sett with 15 cm petiole is comparable with big sett with 30 cm petiole.
