Abstract
This study aims to determine the content and digestibility of dry matter, organic material and crude protein of Taiwan elephant grass planted on coal mine reclamation land. This study used a Randomized Block Design (RBD) with treatment P0=100% N, P and K fertilizer without FMA, P1=100% N, P and K + FMA Glomus manihotis 10 grams/clump, P2=75% fertilizer N, P and K + FMA Glomus manihotis 10 grams/clump, P3=50% fertilizer N, P and K + FMA Glomus manihotis 10 grams/ clump, P4=25% fertilizer N, P and K + FMA Glomus manihotis 10 grams/clump was then carried out in vitro digestibility measurements with 3 different groups of rumen fluid use. The variables observed were Dry Matter digestibility (DM), Organic Matter (OM) and Crude Protein (CP). The results of this study indicated that the adding of different doses of N, P and K fertilizers on the coal mine reclamation land gave no significant difference (P>0.05) on the dry matter, organic matter and crude protein digestibility. The organic matter was ranged from 57.12% (P0) to 58.55% (P4), organic matter was ranged from 58.14% (P0) to 58.55% (P4) and crude protein was ranged from 64.48% (P0) to 71.37% (P4), respectively. From the research results it could be concluded that 25% N, P and K + FMA of Glomus manihotis 10 grams/clump could reduce the use of N, P and K fertilizer up to 75%.
