Pemanfaatan Trichoderma sp Dan Dregs Untuk Pertumbuhan Bibit Kelapa Sawit Pada Medium Gambut Di Pre Nursery

Abstract

Oil palm (Elaeis guineensis Jacq) represent the commodity of primadonna in plantation sector. The problems which is often faced in oil palm agriculture effort is the availability of seed which quality and also availability of potential and fertility soil. Peat soil own some weakness for example is it acidity (pH) and slowly decomposition process. There is one way to overcome the acidity of peat soil is by using dregs and to overcome the faster decomposition proces by giving Trichoderma sp. The objective of this research is kwow the influence of interaction and primary factor of Trichoderma sp and dregs givenees for oil palm seed growth at medium of peat in pre nurery. It's conducted from September 2006 up to Februari 2007. the parameter of this research is to perceived the hight of seed, leaf amount, bar cusp diameter, shoot wet weight, root wet weight, shoot dry weight, root dry weight, and shoot root ratio. The result of this research indicated that the treatment of Trichoderma sp 25 g/ kg of peat + dregs 30 g/kg of peat have a real effect to hight of seed, shoot wet weight, root wet weight, and shoot wet weight. The primary factor of dregs have a real effect to hight of seed and root wet weight at dose of dregs 20 g/kg of peat while leaf amount, shoot wet weight and shoot root ratio at dose of dregs 30 g/kg of peat. The primary factor of Trichoderma sp don't have any real effect at all of parameter.
