Abstract

As a result of not having a more current source of information, citrus managers often base production expectations on the Savage yield tables developed 40 years ago. This paper presents the first analysis of citrus production data collected in southwest Florida for eight scion/rootstock combinations. The results reflect trees planted since 1984 in high density tree spacings. Hamlin production reached over 550 boxes and 3,000 pound solids per acre by year eight. 'Valencia' production also peaked during the eighth year with over 400 boxes and almost 2,800 pound solids per acre. Comparisons between Carrizo and Swingle rootstocks did not indicate significant yield differences.
