A number of accessions of brunswickgrass, Paspalum nicorae (Parodi) have been introduced into the southeastern parts of the United States in recent years. The species is a tropical and subtropical forage species on which little research has been reported.
In this investigation the grass was fertilized with O, 112, 224 and 336 kg/ha N and clipped at 1-, 2-, 3-, 4-, 5-, and 6-week frequencies at approximately 3 mm height. Each increment of N increased forage production significantly but at a reduced rate. The forage yields increases as the clipping interval was lengthened from 1 to 6 weeks with the largest increase between the 2- and 3-week frequencies. Tillers per dm2 and rhizomes per ha were not influenced by either N rate or clipping frequency. Roots per ha were reduced by the 1- and 2-week frequencies and at the lowest N rate. However, all treatments appeared to have sufficient roots to prevent deterioration to the sods.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
