Turfgrass quality usually is related to fertilization management practices. Nitrogen fertilizer formulations are undergoing change in order to produce acceptable turfgrass response and reduce management costs. Field experiments conducted during 1979–81 evaluated the influence of Ca on urea and nitrate N sources on bermudagrass (Cynodon dactylon L.) turfgrass color, quality, verdure, and root-rhizome dry matter production. Color, quality, and verdure were significantly improved and persisted longer with the addition of Ca to urea N sources. Early season root and rhizome production also was increased with the urea + calcium application. Verdure was not significantly affected among the N sources. There was not a significant increase in tissue N content. Addition of Ca to the fertilizer formulation apparently enhanced N utilization.
