Notes
To improve the utilization of Imperata cylindrica var. koenigii as an animal feed, the effects of nitrogen fertilization and cutting interval (Experiment 1) and level of nitrogen fertilizer (Experiment 2) on its productivity and nutritive value were investigated. In Experiment 1 conducted in field, 0 and 10 kg/10a of nitrogen fertilization and 25 days and 75 days of cutting interval were used as treatments. The nitrogen fertilizer level examined in Experiment 2 were 0.2, 0.4, 0.6, 0.8 and 1.0 g/pot. Nitrogen fertilizer and 75 days of cutting interval increased plant dry weight significantly. Growth analyses revealed that the higher RGR in nitrogen fertilized plots was attributed to LAR which was increased by much enlarged leaves (higher SLA) in June and to the increase in NAR in September. The higher RGR in 75 days cutting was mainly the result of higher LAR. Nitrogen fertilization in Experiment 1 and nitrogen at the rate from 0.2 to 0.8 g/pot in Experiment 2 increased protein content but not in vitro dry matter digestibility. Cutting interval of 25 days increased nutritive value of Imperata compared with 75 days cutting.
