Abstract

Seven dwarf coconut cultivars which were subjected to different levels of ammonium sulfate and potassium chloride application responded similarly to fertilization. Fertilization generally improved the growth and precocity of these cultivars with the fertilized palms developing bigger girths, taller stand and retaining more functional leaves than the unfertilized ones. The former also flowered from 0.19 to 1.29 years earlier than the latter. Fertilizer effects were observed earliest on plant height at 3 months after planting.
Among the cultivars, Camotes, Catigan and Malayan Red Dwarf exhibited better growth. Camotes, Catigan, Lingkuranay and Albuera Dwarf were the early bearers whose mean ages at flowering ranged from 3.08 to 3.39 years from planting.
