The edible canna (Canna indica L.) is a rhizomatous flowering herb under the order Zingiberales and is indigenized in the Philippines. Its rhizome is considered edible and can be processed into flour and starch like its counterpart species from Australia - Canna edulis. In the Philippines, this plant is underutilized and commonly considered weed in the wild and urban areas. There are limited information on its potential uses and requires further research on its utilization, production, and processing. To create recommended production practices, an initial study was done to determine the effect of rhizome size on the growth and yield of edible canna. Different rhizome sizes: (T1) 20g, (T2) 50g, and (T3) 100g, were planted in the field at the central experiment station, UPLB [University of the Philippines Los Baños, Laguna, Philippines] and harvested after six months. Regardless of rhizome size, majority of the rhizomes produced shoots/active buds in 12-15 DAP and had almost same shoot growth and development (not significant at alpha=0.05). At harvest, T1 had the heaviest fresh rhizome weight (approx 600g/plant) compared to T2 (576g/plant) and T3 (477g/plant) however, only 12-13% of the peeled rhizome was processed into flour regardless of treatment during planting. From the raw harvested rhizome materials, 6-7% recovery was computed after producing the processed flour. The initial result of this study showed no significant difference between rhizome size but the flour produced is of high quality and had low gluten content.
