Abstract

Oil palm {Elais guineensis Jacq) respresent the commodity of primadona in plantation sector. Hie problem wich is often facedin oil palm agriculture effort is the availability of seed wich quality and also availability of potential and fertility soil. Peat soil own some weakness for example is it acidity (pH) and slowly decompocit process. There is one way to overcome the acidity of peat soil is by using dregs and to overcome the faster decomposition process by giving Trichoderma viride TNJ-63. The objective of this research is know the influences of interaction and primary factor of Trichoderma viride TNJ-63 and dregs giveness for N,P,K absorption of oil palm seed at medium of peat in main nursery. It's conducted from Mei up to September 2008. The parameter of this research is to perceived the higt of seed, leaf amount, bar cusp diameter, shoot dry weight and root dry weight. The result of this research indicated that the treatment of Trichoderma viride TNJ-63 and dregs don't have any real effect to N,P,K absoption of oil palm seed and growth of seed of coconut palm. The interaction factor of time aplication Trichoderma viride TNJ-63 and dregs and the primary factor of dregs and the primary factor of Trichoderma viride TNJ-63 have a real effect to acidity (pH) and C/N ratio.
