【 摘 要 】
Contents of crude protein and crude fiber in harvested material were investigated in kikuyugrass (Pennisetum clandestimum Hochst ex Chiov.), bahiagrass (Paspalum notatum Flugge) and rhodesgrass (Chloris gayana Kunth) grown at Kuju in Oita Prefec., Miyazaki and Naha. Plants were grown under two cutting regimes, namely, cutting at about 20 days interval and about 40 days interval. Investigations were done successively for 2 years. Crude protein content was generally lower and crude fiber content was higher in summer than in other seasons, and crude protein content was negatively and crude fiber content was positively correlated with mean daily air temperature during regrowth period. Each species cut at 20 days interval showed almost no regional difference in the magnitude of the variation of the two contents following the change of the temperature. In the plants cut at 40 days interval, in contrast, the above magnitude was larger in the northern site than in the southern site. However, regional differences were hardly found in the two contents in each species, averaged for the entire growing season. The crude protein content was higher, the crude fiber content was lower and the reduction of annual dry matter yield at the northern site was less in kikuyugrass than in the other two grasses.
