Pengaruh Pupuk Rock Phosphate dan Pupuk Dolomit Terhadap Produksi Kelapa Sawit (Elaeis guineensis Jacq.) di Divisi I PT. Dwi Mitra Adiusaha

Abstract

Oil palm in the process of development is grown in low or marginal nutrients and has a moderate acidity level. In the development process, oil palm requires high enough nutrients for the process of spurring the production process in order to get the expected results, therefore fertilization is carried out optimally with doses according to the recommendations that have been set so that the plants can meet the required nutrients. To increase the yield of fertilization, using rock phosphate and dolomite is very appropriate to get the nutrients needed and can improve the quality of oil palm fruit and the quantity of fresh fruit bunches of oil palm. The effect of Rock Phosphate and Dolomite fertilizers on the production of oil palm (Elaeis Guineensis Jacq) was carried out in the oil palm plantation of PT. Dwi Mitra Adhiusaha which is located in Natai Baru Village, North Mentaya Hilir District, East Kotawaringin Regency, Central Kalimantan. This activity was carried out by analyzing secondary data for both Rock Phosphate fertilizers from 2016 to 2020 and secondary production data from 2017 to 2021. This data analysis used the SPSS method and multiple linear regression which showed that fertilization had a positive correlation and regression towards achievement of oil palm fresh fruit bunches production at PT. Dwi Mitra Adiusaha.
