Oil palm plantations in Indonesia have reached 16.31 million hectares, distributed over various types of soil, including sandy soil. Specific cultivation technology is needed to manage this soil to find profitable oil palm productivity. This study aims to reveal the role of Nephrolepis biserrata as understorey in the performance oil palm yield on sandy soil. The study was carried out in a 14-year-old oil palm plantation, the observations were conducted on mineral soil and sandy soils, both of which were overgrown with N. biserrata, and mineral soils without this vegetation, each trial represented by three estate blocks. Yield performance is indicated by the number of fresh fruit bunches (FFB), FFB weight, and total FFB weight. The results of the study revealed that FFB production in sandy soil + N. biserrata (2.089 ton/ha/month) is higher than mineral soil - N. biserrata (1.963 ton/ha/month). However, the yield rate is still below to mineral soil +N. biserrata (2.299 tons/ha/ month). However, the number and weight of FFB (0.858 FFB/palm/month and 18.032 kg/FFB) in sandy soil + N. biserrata showed no significant difference compared to mineral soil +N. biserrata (0.850 FFB/palm/month and 20.700 kg/FFB). It is also revealed that the use of N. biserrata can improve the stability of the oil palm yield performance between estate blocks on mineral or sandy soils.
