Seleksi Lima Isolat Fungi Mikoriza Arbuskular untuk Pembibitan Kelapa Sawit (Elaeis guineensis Jacq.) pada dua Dosis Pupuk NPK
Abstract: Oil palm (Elaeis
guineensis Jacq.) in Indonesia commonly cultivated on land that is classified
as marginal land such as soil type ultisol with a low fertility rate, so it is
necessary to improve the quality of seeds with the use of arbuscular mycorrhiza
fungi (AMF) and NPK fertilizers. This study aimed (1) to determine the most
appropriate type of AMF for oil palm seedling, (2) to determine the dose of NPK
fertilizeris best for the growth of oil palm seedlings, (3) to determine
whether the response of oil palm seedling stobe determined by the type of NPK
fertilizer, (4) to determine the best dose of NPK fertilizer for each type of
AMF. Research compiled using factorial treatment design (6 x2) with 5
replications. The first factor is the type of mycorrhizal (M) which consists of
6 levels iem0 (without AMF), m1 (Entrophospora sp. Isolates MV 3 ), m2
(Entrophospora sp. Isolates MV12), m3 (Glomus sp. Isolates MV 4), m4 (Glomus
sp. Isolates MV11), and m5 (Glomus sp. Isolates MV13). The second factoris the
dose of NPK fertilizer (P) which consists of 2 level p1 (100% of the
recommended dose), p2 (75% of the recommended dose). The similarity of variance
between treatments were tested with Least Significant Differencetest (LSD) at
5% significance level . The results showed (1) All types of FMA being tested
can increase the growth of oil palm seedlings compared without exception AMF
Glomus sp. MV isolates 11, (2) dose of NPK fertilizer 100% of recommended doses
produce the best growth of oil palm seedlings shown by the fresh weight of
shoot, dry weight of shoot, fresh weight of root, dry weight of root,and leaf
greenness level, (3) palm seedling growth response to AMF inoculationis not
determined by a given dose of NPK fertilizer, (4) there is no optimum dose of
NPK fertilizer for each type of AMF were used.
