Nitrogen utilization in creeping bentgrass

Efficient approaches for screening nitrogen utilization efficiency (NUE) of turfgrasses are needed, since nitrate contamination of ground water is a concern on golf courses. In the first study, the conditions of N utilization of fourteen bentgrass cultivars were compared in hydroponic solution culture. There were significant differences between cultivars in plant tissue dry weight, tissue N content, root absorption efficiency (RAE), and NUE. From a whole plant basis, 'Penncross' accumulated the highest N accompanied with the highest whole plant dry weight (WPDW). 'Regent' had the highest NUE while 'Allure' had the lowest NUE. Nitrogen absorption efficiency values were comparatively higher in 'Allure' than all the other cultivars. Differences in NUE among most cultivars were correlated to plant dry weight.
