Crop cultivation and maintenance: The experimental site was plowed in late March 2006. Soil samples were taken from depths of 0-15 cm as composites of four samples from four random locations within each plot. Limestone was applied at 937.5 kg/ha based on the soil analysis, before planting 7 days. The basal fertilizer with 625 kg/ha of 15-15-15 fertilizer and 6.25 t/ha of cattle manure were provided to the experimental plots. Planting King Napier grass by stem cutting with 2 nodes a piece and placed 45 with 2 pieces a hole with plant o spacing of 50 x 80 cm in 3 x 4 m plot size. Each plot was applied urea at 125 kg/ha after each cutting and applied cattle manure at 1,562.5 kg/ha every 3 months. The entire plot area was kept weed-free with hand hoeing after cutting and irrigated whenever necessary.
