Abstract: Native warm season grasses are productive summer-producing forage crops that support excellent grazing animal performance. These grasses would form a valuable part of an improved forage pasture system, providing good forage during a time when the predominant cool-season forage species are not productive. The objective of this study was to determine the effect of variety on total and seasonal yield of eastern gamagrass, switchgrass, indiangrass, and big bluestem. Varieties were established on a Maury silt loam in July 2000 using transplants grown in float trays in a greenhouse. Experimental design was a randomized block replicated four times. Two harvests were made in 2001 for three of the species while indiangrass varieties matured late and were harvested only once. First harvests were made when most of the varieties were at 50% emergence of inflorescence. Means for dry matter yields by species were 14.6, 14.3, 13.4, and 10.5 Mg ha-1 for indiangrass, gamagrass, switchgrass, and big bluestem, respectively. In 2001 switchgrass and big bluestem varieties produced 72% and 70% of their total yield respectively by June 30. In contrast, 38% of eastern gamagrass occurred prior to June 30.
