Abstract :The amount of fertilizer used as source of nutrients play an important role for successful growth of oil palm. In this study, the effect of different amount of nitrogen insert ignore into journalissuearticles values(N); and potassium insert ignore into journalissuearticles values(K); fertilizer on the biochemical properties of oil palm were studied. The fertilizer consist of constant amount of Bayovar rock phosphate insert ignore into journalissuearticles values(BRP);, Kieserite insert ignore into journalissuearticles values(KS);, and Foliar Boron insert ignore into journalissuearticles values(F’Bor);, as well as different levels of muriate of potash insert ignore into journalissuearticles values(MOP); and ammonium sulphate insert ignore into journalissuearticles values(AS);. The treatments were labeled as T1, T2 and T3. Six planting materials indicated as A, B, C, D, E and F were tested. The total phenolic content insert ignore into journalissuearticles values(TPC); and total flavonoid content insert ignore into journalissuearticles values(TFC); in the leaves of the oil palm trees were analyzed using folin-ciocalteu method and aluminium chloride method, respectively. Results showed that the leaves of planting material A and F showed significant responses towards fertilizer levels where the TPC ad TFC contents reduced at the highest fertilizer level. Planting material C and D responded quite similar in terms of TPC content with planting material A and F, respectively. Overall, different planting materials showed different pattern of responses specifically for TPC and TFC towards fertilizer level.
