Respon Tanaman Kelapa Sawit (Elaeis Guineensis Jacq.) Terhadap Pemberian Kombinasi Pupuk Polyhalite Dan Kcl Pada Tanah Dystrudepts

Oil palm (Elaeis guineensis Jacq.) is widely cultivated in Indonesia, especially in Riau Province, where many plantations are located on marginal soils like sandy-textured Dystrudepts which have high percolation and nutrient leaching. To address this, slow-release fertilizers like Polyhalite are suitable but require potassium supplementation, such as with KCl. This study aims to examine the effects of Polyhalite and the combination of Polyhalite with KCl, as well as to determine the best combination for the growth and yield of oil palm (Elaeis guineensis Jacq.) in Dystrudepts soil. This study was conducted in a smallholder oil palm plantation in Petapahan Village, Tapung District, Kampar Regency, Riau Province.The research lasted for six months, from October 2023 to March 2024. The research design used is a Completely Randomized Design (CRD). The treatments used were NPK 3.3 kg, Polyhalite 2 kg + KCl 1.4 kg, Polyhalite 4.1 kg + KCl 1 kg, Polyhalite 6.1 kg + KCl 0.5 kg and Polyhalite 8.1 kg. Data from the analysis of variance that had a significant effect were further tested using Duncan's New Multiple Range Test (DNMRT) at the 5% level. The parameters observed were plant height, rod circumference, midrib length, number of leaflets, bunch number, bunch weight and total bunch weight. The results of the six-month study indicated that the application of Polyhalite and its combination with KCl had no significant effect on the parametersof plant height,rod circumference, midrib length, and numberof leaflets in oil palm. The application of Polyhalite and its combination with KCl had a significant effect on the parameters of the number bunches, bunch weight, and total bunch weight. The best dosage for increasing bunch weight was Polyhalite 8.1 kg.
