The oil palm plantations in Bengkalis Regency have been continuously expanding, with the cultivated area increasing from 130,546 ha in 2021 to 133,798 ha in 2022 (BPS, 2022). Despite their significant contribution to the local economy, the immature phase of oil palm plants (TBM I) requires special attention as no yield is generated during the initial 30 months. During this period, high maintenance costs are incurred, particularly for fertilization and weed control. To address this, farmers are encouraged to grow intercrops such as mung bean, which utilize the vacant spaces while providing additional income.
Mung bean is a suitable intercrop due to its drought tolerance, ability to thrive in less fertile soils, and its agronomic and economic benefits. The combination of NPK fertilizer and compost, such as that derived from oil palm empty fruit bunches, can enhance soil fertility and mung bean productivity. Compost improves soil quality, supports photosynthesis, and facilitates the formationofrootnodulesinleguminousplants.Optimizinglandusewithintercrops enables farmers to reduce oil palm maintenance costs while generating additional income during the waiting period for harvest. The objective of this study is to determine the optimal doses of NPK fertilizer and compost for the growth and yield of mung bean (Vigna radiata) cultivated as an intercrop in a 7-month-old oil palm plantation.
The study was conducted in a seven-month-old oil palm TBM I plantation in Langkat Village, Siak Kecil Subdistrict, Bengkalis Regency, from September to December 2024. A Randomized Block Design (RBD) with two factors was employed: NPK fertilizer dosage (150, 250, 350 kg/ha)and compost dosage (0, 1.5, 3 tons/ha), with three replications. Observed parameters included plant height, number of branches, flowering and harvest time, number of pods per plot, pod weight per plot, seed weight per plot, weight of 100 seeds, transpiration rate, photosynthesis rate, stomatal conductance, and chlorophyll content. Data were analyzed using analysis of variance (ANOVA) at a 5% significance level, followed by DMRT at 5%.
The results of the study indicated that there was no interaction between compost fertilizer and NPK on all observed parameters. However, a significant effect of the single factor of compost fertilizer was observed on chlorophyll content, plant height, flowering time, harvesting time, number of pods, pod weight, and seed weight per plot. Additionally, the single factor of NPK had a significant effect on flowering time. The combination of NPK at 350 kg.ha⁻¹ and compost at 1.5 tons.ha⁻¹ tended to produce higher yields of mung bean plants.

Keywords: Mung bean (Vigna radiata L.), NPK, Compost, 7-month-old oil palm.
