This research aim to obtain a best combination of kascing fertilizer dosage utilization and mushroom inoculant of Mikoriza Arbuskula (CMA) for the growing of oil palm seed in pre nursey. Pot experiment was held in a half image wire house, Agricultural Faculty of Andalas University since February 2001 until July 2001. This experiment use Complete Random Sampling by seven treatment combination and three repetition. The results of research indicates that the utilization of kascing fertilizer package and CMA incoulant willincrease the growing parameters, such as : 1) The height, weight of seed, dry weight of crown, the number of roots, percentage of infected roots, total available P nutrient in the soil and P nutrient in oil palm seed; 2) The decreasing of crown / root ratio of the utililization of kascing fertilizer and CMA inoculant that caused by the increasing of crown dry weight that less than increasing of dry weight of root. In order to increase the growing of oil palm seed in pre-nursey, combination of 2,5 g kascing fertilizer and 10,0 g CMA inoculant is needed.
