Abstract:Different site characteristics, namely soil properties, elevation, and exposure to sunlight influencing the growth rate were evaluated in 15 palasan (Calamus merrillii) plantations located all over the Philippines. Growth rate was highly affected by soil pH, organic matter, nitrogen, potassium and phosphorus contents. Site elevation, exposure to sunlight and topography also gave a direct impact on cane production. Based on the regression coefficient, the influence of site parameters follows the trend: elevation > exposure to sunlight > soil properties. These parameters should be first considered in the selection process of future plantation sites to achieve optimum cane production.
