Abstract/Contents: | "Several slow-release nitrogen (N) sources, applied as single spring treatments at 98 kg N/ha, were compared to a single application of water-soluble N in April at 98 kg N/ha or 49 kg N/ha applied in April and repeated in June to evaluate their effect on centipedegrass [Ereomchloa ophriuroides (Munro) Hack.] performance. In spring, Escote 100, IBDU (fine, isobutylidene diurea), sulfur-coated urea (SCU) and SCU + AN provided color equal to NH4NO3 (AN), but only treatments containing SCU produced turfgrass quality equal to AN. During the summer, all slow-release N carrier treatments provided turfgrass quality and color that was equal to or better than that provided by AN. Ureaform (UF) resulted in better late fall color than did AN, but fall quality ratings were similar regardless of N source. Thatch accumulation was similar for all treatments and no centipede decline was observed. Leaf N content was not markedly influenced by treatment and no consistent trend in relative growth rate among N sources was apparent. Thus, while no single slow-release N source provided a season-long advantage over AN applied in April, all could be used effectively on centipedegrass." |
