Production of sugarcane and tropical grasses as a renewable energy source. First quarterly report, 1980-1981
Research continued on tropical grasses from Saccharum and related genera as sources of intensively-propagated fiber and fermentable solids. Final yield data for the second-ratoon crop of sugarcane and napier grass was compiled during the first quarter. The highest green matter yield for sugarcane was 92.0 tons/acre year (variety NCo 310). The highest dry matter yield, including trash, was 31.3 tons/acre year. For napier grass the highest green and dry matter yields were 88.9 and 22.4 tons/acre year, respectively. Sugar-cane quality was generally low but sugar yields were favorable when computed on a per acre basis. Sucrose content averaged 7.20% for all varieties and row spacings. Fiber content averaged 16.4%. The second ratoon crop averaged 6.18 tons sugar/acre (TSA) at standard row spacing and 5.71 TSA at narrow row spacing.
