Description

In order to improve growth and seasonal productivity of bahiagrass (Paspalum notatum Flugge) during the low temperature season in southern Kyushu, growth attributes, forage yield and quality of a new genotype, "Tifton 9", which was bred in and introduced from the United States, was compared to current genotypes, "Pensacola" and "Nanou", for 4 years after the year of establishment. Observation and cutting of herbage were conducted every month in the second and third years and every 2months in the fourth and fifth years. "Tifton 9" showed superior growth and yielding ability during the low temperature season, resulting in stabilization of seasonal productivity and improvement of annual dry matter (DM) yield cut every month in the second and third years. In vitro DM digestibility (IVDMD) as forage quality did not differ among three genotypes and correlated negatively (P<0.05) with DM yield for both 1- and 2-month intervals. Other quality attributes did not differ among genotypes. The average values for IVDMD and concentrations of crude protein, neutral detergent fiber, acid detergent fiber and acid detergent lignin in "Tifton 9" across whole cuttings in the fifth year were 49.4, 6.5, 70.5, 42.1 and 6.7%, respectively. Respective forage quality of "Tifton 9" is equivalent to a standard value among common tropical grasses.
