Abstract

Field experiments were conducted to determine the nutrient uptake of taro to which controlled release (CR) and fast release (FR) fertilizers were applied. A factorial experiment in randomized complete block design with three replications was conducted in each site. Four nitrogen treatments, three harvest dates and two sites were the experimental factors examined. The results showed that interactions between sites, harvest dates and nitrogen sources were significant (P<0.05) for the variables analysed. Hence, FR fertilizers resulted in the maximum N, P, Ca, Cu, Fe and Zn uptake at 6 months after planting (MAP). Also, the application of FR fertilizers resulted in the maximum P and Cu uptake at 2 MAP. Meanwhile, CR fertilizers resulted in the maximum K, Ca, Mg and Cu uptake at 4 MAP. Also, CR fertilizers resulted in the maximum Mn uptake at 6 MAP. Therefore, the application of FR and CR fertilizers enhanced the nutrient uptake of taro plants with temporal variation.
