Abstract

The development of agarwood (Aquilaria malacensis Lamk) plantation the mid of oil palm plantation is are of agroforestry systems, which needs to be further observed, especially spacing. The spacing influenced light intensity, which is the further the distance the more light could be capture by agarwood plants, and the shaded area decreases. The study is aimed to observe the optimum spacing in the oil palm plantation. The study site was located in Rokan Hulu Riau. The study employed a Randomized Block Design (CRBD) with three treatments for spacing: 2, 3 , and 4 m. Parameter observed are the growth (height, diameter, and survival rate and micro climate, and biophysicalcharacteristics). The result of the study indicators the spacing as treatment did not show significant effect to the growth of Aquilaria malacensis Lamk up tot 24 months old. However after 30 months the effects of the spacing is demonstrated for which four m spacing is the better for the growth and diameter of Aquilaria malacensis Lamk.
