Comparison of yields by tree age and rootstock in Southwest Florida orange groves

Fritz M. Roka, Robert E. Rouse, Ronald P. Muraro

Abstract


A study to provide citrus managers with information on high-density citrus plantings in southwest Florida was initiated in the early 1990s. The first report has been published (Roka et al., 1997), providing yield data for 'Hamlin' and 'Valencia' sweet oranges [Citrus sinensis (L.) Osb.] for nine-year-old trees. This paper is a summary of the southwest Florida yield study for trees 13 years of age. Analysis of yield comparisons between Swingle citrumelo (C. paridisi × Poncirus trifoliata) and Carrizo citrange (C. sinensis × P. trifoliata) rootstocks found a numerical but not consistent statistical difference under commercial production.
