Serapan P dan Pertumbuhan Bibit Kelapa Sawit (Elaeis gueneensis Jacq.) dengan Pemberian Abu Terbang (Fly Ash) dan Fosfat Alam pada Medium Gambut

Abstract

The study aims to determine the interaction of the provision of fly ash (fly ash) and phosphate (ERP) for P uptake and growth of seedlings of oil palm on peat medium . Research carried out in the form of factorial experiment using a completely randomized design . The first factor of fly ash ( 0, 25, 50 and 75 g/polybag ) and the second factor is the natural phosphate (0, 8, 10 and 12 g/polybag). Any combination treatment was repeated three times . Data were analyzed statistically using analysis of variance and tested further by DMNRT level of 5% . The results showed that the fly ash effect on the root volume , but had no effect on plant height , leaf number , diameter tubers , plant dry weight , total P uptake in plants and fertilizer P. P and interaction with the fly ash natural phosphate had no effect on plant height , number of leaves, diameter tubers , root volume , dry weight of the plant , total P uptake in plants and P.
