Technical Abstract: Common, `Coastal', and `Tifton 85' bermudagrass [Cynodon dactylon (L.) Pers were grown under swine effluent fertilization. Plants from two harvests in 1997 and three in 1998 were hand separated into leaf, stem, runner, and roo components and evaluated for P, N, K, Zn, and Cu concentration and uptake. Common had greater P concentration in stems, leaves, and runners than the other cultivars. Tifton 85 had greater N concentration in stems and runne though common had greater N concentration in leaves. Little difference was noted between cultivars for P or N uptake. Tifton 85 had greater K concentration in all plant parts and greater Cu concentration in runners an roots. Tifton 85 had greater K and Cu uptake in runners and total plant th the other cultivars. Few differences were noted for Zn concentration and uptake. Runners contained the most N, P, K, Cu, and Zn, with 63-75% of the nutrients located in nonharvested plant parts (runners and roots). Stem an nleaf production should be maximized and runner formation minimized to impr nutrient uptake in harvestable portions of bermudagrass.
