Different planting materials from underground tuber and headsett of Gabing San Fernando (Xanthosoma sagittifolium L. Schott. Milet) were tested in 2 separate propagation studies to determine the most practical and efficient propagation technique for rapid multiplication of Gabing San Fernando (GSF). For the underground tuber study, 5 planting materials: whole corm, top half corm, bottom half corm, and cormel were tested in actual field condition while for the headsett study, 5 planting materials; small cormsett (29-32 mm) and 15 cm petiole, small cormsett with 30 cm petiole, big cormsett (42-59 mm) with 15 cm petiole, big cormsett with 30 cm petiole, and small cormsett with intact shoots were tested in germination plots. Results of the underground tuber study showed that whole corm and top half corm were able to establish early, with statistically comparable percentage germinations, which are statistically higher than the other treatments throughout the 6 weeks of observation, attaining 100% germination on the 5th-6th week. The use of bottom whole corm performed poorly in the first 2 weeks but was able to catch up in the 3rd week, attaining 100% germination on the 6th week. However, the results show that early plant establishment did not have advantage on plant growth in terms of plant height, stem girth, and petiole length. Results of the headset study showed that all treatments gave a comparable high percentage survival of the propagules on the 1st month except for small corms with intact shoots. However, there was significant difference between the different headset planting materials on plant height, stem girth, petiole length, and number of leaves throughout the 5 weeks of observation.
