Abstract

AbstractEffort to increase the production of oil palm can beconducted through application of plant growth regulator(PGR). Orgamin biostimulan is a natural PGR formulathat has been tested to improve the vegetative growths ofcorn and oil palm in the glass house. Assessment ofOrgamin and Orgamin plus (Orgamin + micro nutrient)applications at commercial scale was carried out inMarjandi oil palm plantation of PTPN IV usingrandomized block design with three treatments, i.e. K =100% recommended dose of inorganic fertilizer(control), O= Orgamin (1.5 kg/tree) + 50% dose ofinorganic fertilizer, OP = Orgamin plus (1.5 kg/tree)without inorganic fertilizer. The parameters ofobservation at 2.5 months after the treatments were soiland leaf nutrient contents (N, P, K, Mg), percentage offemale flower, mesocarp oil content, and harvested freshfruit bunches (FFB). The observation showed that therewas an increased in oil yield, weight of FFB and leafnutrient content, while the percentage of female flowerand nutrient content of soil were not significantlydifferent compared to the control.AbstrakUpaya untuk meningkatkan produksi kelapa sawitdapat dilakukan antara lain melalui pemberian zatpengatur tumbuh (ZPT).
