Pemberian Berbagai Macam Pupuk Hayati Dan Pupuk Npkmg Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq.) Di Main Nursery
ABSTRACT
Oil palm is the largest oil-producing crop in Indonesia. Increasing sustainable oil
palm production is done by rejuvenating old and damaged plants. In rejuvenation,
the quality of seedlings is considered such as the availability of nutrients in the
media. The purpose of this study is to determine the interaction of various types of
biofertilizers with NPKMg fertilizers, the single factor of biofertilizers and
NPKMg, as well as the best dose of biofertilizer and NPKMg on the growth of oil
palm main nursery seedlings. This study is a factorial experiment of Complete
Random Design. The first factor consists of three biological fertilizers, namely
H1: 80 g CMA, H2: 40 g Tricoderma sp., H3: 20 g BPF and the second factor
consists of 3 levels of NPKMg 12-12-17-2 fertilizer, namely P1: 27 g, P2: 33.5 g,
P3: 40 g. The parameters observed were plant height increase, leaf number
increase, hump diameter increase, root volume, fresh weight of the bush, dry
weight of the plant and root crown ratio. The application of BPF biofertilizer at a
dose of 20 g and NPKMg fertilizer at a dose of 40 g per plant is able to increase
the growth of seedlings in the main nursery.
Keyword: Biofertilizer, diameter increase, height increase.
