Growth and Nutrient Partitioning of `TifEagle' Bermudagrass as Influenced by Nitrogen and Trinexapac-ethyl

Patrick E. McCullough; Haibo Liu; Lambert B. McCarty; et al. HortScience 2006. doi:10.21273/hortsci.41.2.453

Other claims from this paper (12)

Intervention effect Trinexapac-ethyl enhanced turf quality on every date after initial application.
Association After 8 weeks, high N rates were associated with a decline in turf quality.
Intervention effect TifEagle bermudagrass treated with TE had clippings reduced by 52% to 61% relative to non-TE treated turf.
Intervention effect After 16 weeks, bermudagrass treated with TE over all N levels had 43% greater root mass than non-TE treated turf.
Intervention effect After 16 weeks, bermudagrass treated with TE over all N levels had 23% enhanced root length relative to non-TE treated turf.
Intervention effect In TE treated turf, leaf N, P and K concentrations were consistently lower than in non-TE treated turf.
Intervention effect In TE treated turf, Ca and Mg concentrations were increased relative to non-TE treated turf.
Intervention effect Root N concentrations in TE treated turf were 8% to 11% higher than at the respective N rates without TE.
Intervention effect Clipping nutrient recoveries were reduced by 69% to 79% by TE relative to non-TE treated turf.
Intervention effect TE increased the nutrients recovered in roots by 25% to 105% relative to non-TE treated turf.
Association Bermudagrass treated with TE had higher total chlorophyll concentrations after 8 and 12 weeks.
Mechanism Inhibiting leaf growth appears to reallocate nutrients to belowground tissues, thereby improving nutrient use efficiency and root growth.
