Abstract
The objectives of this study were to determine the growth response of dwarf napiergrass (Pennisetum purpureum Schumach) to digested effluent of manure (DEM). Liquid form of DEM (LDEM) produced from biogas-plant and different rates of manure enriched with LDEM (SDEM) were applied to dwarf napiergrass. The plant height, tiller number, leaf area and total dry matter weight (TDMW) significantly increased with the increasing manure application in dwarf napiergrass. This yielding ability was derived from high accumulation of dry matter in root and underground stem part to show lower top to root ratio below 2 in this genotype. Both LDEM and SDEM were so effective in enhancing plant growth as in chemical fertilizer, while the efficiency of total N content to yielding ability was the least in SDEM, followed by LDEM and chemical fertilizer with no-significant difference among treatments in dwarf napiergrass.
