Abstract
Good sustainability practices are major challenges in smallholder oil palm cultivation. This study examined the combination of empty fruit bunch (EFB) compost and chemical fertilizer application to address the continual chemical fertilizer application associated with environmental degradation. The study used a Randomized Complete Block Design with five treatments replicated four times in a smallholder farm in Sarawak. The treatments were: T1 (EFB Compost) T2 (EFB Compost Korn-kali) T3 (KornKali) T4 (NPK) and T (EFB Compost NPK). At Month 9 the soil total N was highest in T1 (0.43) and lowest in T3 (0.34). This trend was also observed in plant N (0.70 “ 1.23 ). Soil available P was lowest in T3 (13.80 mg kg-1) with T4 and T5 the highest (15.90 mg kg-1). Similarly plant P was lowest in T3 (0.14); however T5 was the highest (0.33 ). There were significant differences in both the soil available P and plant P as ANOVA indicated p0.00. Soil K was lowest in T3 (0.55 cmolc kg-1) while highest in T1 (0.65 cmolc kg-1). Plant K was also lowest in T3 (1.30 ) while T4 was highest (1.83). Both soils available P and plant P showed significant differences with ANOVA indicating p0.00. However T2 and T5 produced higher leaf area at 1900 cm2 and 2100 cm2 and average bunch weight at 20.1 kg and 10.1 kg respectively significantly different from single fertilizer application. The study concluded that the combination of EFB compost and chemical fertilizer could be adopted as mitigation to reduce chemical fertilizers application.
