Abstract

Oil palm plants are currently experiencing rapid growth and have promising commercial opportunities in the future, it is necessary to pay attention to the quality of palm oil seedlings for cultivation to achieve high productivity. Fertilization during the early seedling stage of oil palm using raw materials from fish waste can reduce the use of chemical fertilizers. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) non faktorial dengan taraf 5 perlakuan terdiri dari 4 kali ulangan sehingga terdapat 20 satuan percobaan, setiap satuan percobaan terdiri dari 4 bibit kelapa sawit sehingga total unit percobaan 80 tanaman. Perlakuan terdiri dari G0 (Biofertilizer asam amino ikan 0 mL/L disiram air), G1 (Biofertilizer asam amino ikan 10 mL/L), G2 (Biofertilizer asam amino ikan 30 mL/L), G3 (Biofertilizer asam amino ikan 50 mL/L), G4 (Biofertilizer asam amino ikan 70 mL/L). Data yang diperoleh dianalisis menggunakan sidik ragam. If the treatment has a significant effect, a further DMRT (Duncan’s Multiple Range Test) test will be conducted at the 5% level. The research results show that the G4 treatment with a fish amino acid biofertilizer concentration of mL/L is the best treatment concentration in improving plant height parameters of 26.35 cm, leaf length of 18.09 cm, stem diameter of 5.47 mm, leaf chlorophyll of 45.36 SPAD, and plant dry weight of 1.63 g.

Abstract

Ultisol media are physically relatively infertile and low in organic matter content. This study aims to determine the effect of rice husk biocharand chicken manure compost on the growth of oil palm seedlings in ultisol soil media. The study was conducted from April to June 2025 at the experimental farm on Jalan Gusti Mesir, Medan Jaya Village, Simpang Hilir Subdistrict, Kayong Utara Regency. The experiment used a factorial RAL design consisting of two treatment factors. The first factor was rice husk biochar, which consisted of 3 levels, namely B0 = without biochar, B1 = 75 g/polybag, and B2 = 150 g/polybag. The second factor was chicken manure compost with 3 levels, namely K0 = without compost, K1 = 375 g/polybag, and K2 = 450 g/polybag. The observation parameters included plant height, stem diameter, number of leaves, root length, root volume, and soil pH. The data were analyzed using analysis of variance, and if there was a significant effect, it was followed by Duncan's Multiple Range Test (DMRT) at a 5% level. The results showed that the application of rice husk biocharand chicken manure compost had a significant effect on oil palm seedling growth. The best dose was obtained from the combination of 75 g of biochar and 375 g/polybag of compost, which significantly increased plant height, stem diameter, number of leaves, root length, root volume, and soil pH.
