Effects of fertilizers on growth and leaf nutrient content of clonal oil palm seedlings

Caonal oil palm offers the potential for greater productivity because it is possible to establish uniform tree stands comprising identical copies (clones) of a limited number of highly productive oil palms. There is limited information on the most suitable fertilizer type, method and rates of applic...

Two separated factorial completely randomized design polybag experiments were conducted at Gomantong Estate, Kinabatangan, Sabah.

Based on foliar analysis results these clonal seedlings exhibited B deficiency as low at 10 (ppm) or below. Based on the result on these experiments the standard operating procedures for fertilizers (method of application, rate of application and NPK ratio) practiced by the industry is sufficient for the clonal seedlings. For experiment 1, based on the monetary cost benefit analysis the slow release fertilizer was RM0.05 cheaper than the conventional fertilizer per seedling.
