The Effect of Natural Bioactivators on Growth and Nutrient Content of Taiwan Grass (Pennisetum purpureum schumach) in Marginal Soil

level. Parameters of this research are fresh content, tiller number, plant height, dry weight, organic matter, water content, crude protein, crude fat, extract material without nitrogen, nitrogen, and ash of Taiwan grass (Pennisetum purpureum schumach) with 4 treatments i.e T-1, T-2, T-3 and T-4 and three groups of liquid organic fertilizer level i.e 5 ml; 10 ml; 15 ml and 20 ml. The results showed that the treatment had not significantly affected (P> 0,05) on the production and nutrient content of Pennisetum purpureum schumach in range of 5 ml to 20 ml. However, organic liquid fertilizer with the addition of natural bioactivator of noni fruit has better nutrient content than other fruit that is N = 1,84% P2O5 = 2,29%, K2O = 2,5% and pH = 5,04.
