Efek Pemberian Pupuk Anorganik Npkmg Dan Pupuk Organik Super K Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq) Umur 7 – 13 Bulan
ABSTRACT
This study aims to determine the effect of giving inorganic fertilizer
NPKMg and organic super K fertilizer and to get the best combination dose of
inorganic fertilizer NPKMg and organic super K fertilizer on the growth of oil
palm seedlings at the age of 7 – 13 months. This research was conducted for 6
months starting from October 2020 to April 2021. Using a factorial Completely
Randomized Design (CRD). The first factor is inorganic fertilizer NPKMg with 2
levels, namely A1: 7,5 g per 10 kg of media, A2: 10 g per 10 kg of media. The
second factor is super K organic fertilizer with 3 levels, namely K1 : 6,25 g per 10
kg of media, K2 : 12,5 g per 10 kg of media, K2 : 18,75 g per 10 kg of media.
Parameters observed were plant height, number of midribs, leaf width, leaf length
and bulb circumference. The data obtained were analyzed statistically using
analysis of variance and further tested with Duncan's New Multiple Range Test
(DNMRT) level 5% using the SPSS application. The results showed that the
application of inorganic fertilizer NPKMg 10 g per 10 kg of media was able to
increase the growth of oil palm seedlings in the main nursery. Application of
organic fertilizer super K 12,5 g per 10 kg of media was able to increase the
growth of oil palm seedlings. The combination of inorganic fertilizer NPKMg 10
g per 10 kg of media and organic fertilizer super K 12,5 g per 10 kg of media gave
the best results for the growth of oil palm seedlings.
