Respon Pertumbuhan Kelapa Sawit Bibit ( Elaeis guineensis Jacq.) Terhadap Jenis fungi mikoriza arbuskula pada Dua Tingkat Pemupukan NPK
Abstract: Oil palm (Elaeis
guineensis Jacq.) is one of the important excellent crop plantations which have
significance for the development of national farm and country source of foreign
exchange earnings.Oil palm cultivation is mostly done on the ground of ultisol
that have constraints phosphorus deficiency that needed improvement in the
quality of the nursery with the utilization of arbuscular mycorrhiza fungi
(AMF). The study aimed: (1) determine the best type of AMF in enhancing the
growth of oil palm seedlings, (2) determine dose of NPK fertilize most appropriate for the oil
palm seedling, (3) determine whether the response of oil palm seedlings to type
AMF influenced by dose NPK fertilizer, and (4)determine the best dose of NPK
fertilizer for each type of AMF. The treatment design is a factorial (6x2)
arranged in randomize completely block design with 5 replications. The first
factor is the type of AMF, design as without AMF, Glomus sp. Isolate MV 23,
Glomus sp. Isolate MV 26, Entrophospora sp. Isolate MV 22, Entrophospora sp.
Isolate MV 25, Entrophospora sp. Isolate MV 28.The second factor is number of
NPK fertilize design as p1 (100 % from recomendation) and p2 (50 % from recomendation). Means homogeneity among the treatments were
tested using Barlett test and the aditivity data were tested with Tukey test.
Separation of means value were analyzed using Least Significant Difference
(LSD) at 5% significance level. The results showed the interaction between the
type and dose of NPK fertilizer AMF is can be concluded that (1) oil palm
seedlings response to AMF inoculation type is determined by the dose of NPK
fertilizer on the variable plant height, dry weight of root, and number of
primary roots, 2) the optimum dose for each type of AMF are used based on the
data root dry weight is a combination of 100% NPK fertilizer with each type of
AMF, excepton the AMF types Entrophospora sp. Isolates MV 22.
