| Abstract/Contents: | "White clover (Trifolium repens L.) inclusion is a proposed means of increasing the sustainability of low-maintenance turfgrass scenarios due to its ability to biologically fix N and transfer it to associated grasses. Little is known about white clover N contribution to maintained warm-season turfgrass swards. A 3-yr study was conducted to evaluate the effects of white clover inclusion within a hybrid bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt Davy] lawn. Supplemental N (0, 0.5, 1, 2, 4, and 8 g N m-2) was applied monthly, from April to August, to test the effects of supplemental N on biomass composition, N fixation, and N transfer. Mixed grass plus clover swards yielded higher clipping biomass than grass-alone swards, which was evidence of enhanced bermudagrass growth due to biological N fixation. Likewise, grass biomass of mixed swards was increased relative to that of grass-alone swards at supplemental N rates ā¤10 g N m-2 yr-1 but was decreased at higher supplemental N rates. Nitrogen fixation was estimated to be 6.6 g m-2 yr-1 during the 3-yr study, with an apparent increase in fixation as years progressed. Results indicate that N fixation was suppressed at the lower and upper extremes of supplemental N rates. Nitrogen transfer to the associated bermudagrass sward was estimated to be 24% during the latter 2 yr of the study. These results offer evidence of white clover utility when included within maintained warm-season turfgrass scenarios." |
