Abstract

This study aimed to determine nutrient content, fiber fraction, and ethanol production of three cultivars Pennisetum purpureum Schumach. Cultivars: tifton, king Thailand and local. The design of this study completed a randomized design of three Pennisetum purpureum Schumach cultivars, with three replications for each dose.Grasses were planted with space 1x1 m and then divided into three plots. Variables observed in the study included nutrient content (dry matter, organic matter, crude protein, ether extract, and nitrogen-free extract), fiber fraction (crude fiber, neutral detergent fiber, and acid detergent fiber) and ethanol production. Data obtained were statistically analyzed using analysis of variance as completed randomized design and continued with Duncan’s new multiple range test for any difference detected. The results showed that cultivar’s variety of napiergrass was significant (P<0.05) on dry matter, crude protein, neutral detergent fiber, and ethanol production. King Thailand produced the highest dry matter (20.82%), crude protein (11.85%), neutral detergent fiber (69.55%), and ethanol production (55, 90 l/ton). Based on the results of the study it can be concluded that napiergrass cultivars give different results on dry matter, crude protein, neutral detergent fiber, and ethanol production. The best cultivar is King Thailand because it has the highest value on dry matter, crude protein, neutral detergent fiber, and ethanol production.
