Abstract

The results showed that a significant interaction affected the number of partially filled pods per plant, dry seed weight per plot, and 100-seed weight. Individually, oil palm empty fruit bunch (EFB) ash significantly affected plant height, flowering age, root nodules, leaf greenness, and pod yield parameters, while urea significantly influenced plant height, flowering age, root nodules, leaf greenness, and dry pod weight per plot. The optimal treatment combination was 50 kg ha⁻¹ urea with 6 ton ha⁻¹ oil palm EFB ash, producing the highest dry seed weight (269.60 g per plot). The most favorable single-factor responses were obtained at 4 ton ha⁻¹ oil palm EFB ash for overall vegetative performance and at 50 kg ha⁻¹ urea for nodulation and yield-related traits.
