191 cm, while in the control plots, it was only 107 cm. Plant growth promotion plays
a role in this improvement along with the sufficient nutrients and symbiotic systems
from other substances.
The oil palms in Siak are productive (13 years old), unlike those in Palangka
Raya, because it is an abandoned area. Within one month, the oil palms can be
harvested up to two times. According to calculations in the field experiment, there
was an improvement in the total harvested fresh fruit bunches (FFBs) in the
treatment plot. The total harvested FFBs in the treatment plots were 21 ton/ha/
year, while in the control plots, only 16 ton/ha/year FFBs were harvested,
representing a 5 ton/ha/year difference.
