This research investigates how different dosages of rice husk charcoal and NPK fertilizer affect the growth of oil palm seedlings.
Conducted in a randomized design with two factors: rice husk charcoal and NPK fertilizer dosages.
Tested three levels of rice husk charcoal (200 g, 250 g, 300 g) and three levels of NPK (5 g, 7.5 g, 10 g).
Utilized ANOVA for analysis and DMRT for significant differences at a 5% level.
The highest fresh weight of seedlings (40.60 g) was from 200 g rice husk charcoal and 10 g NPK fertilizer.
Stem diameter (19.97 mm) and leaf number (6.75 leaves) peaked at 300 g rice husk charcoal.
At 10 g NPK fertilizer, plant height reached 18.78 cm with 6.58 leaves.
