Abstract

Abstract Bermudagrass (Cynodon dactylon (L.) Pers.) interference reduced yield of ‘Valencia’ oranges (Citrus sinensis (L.) Osbeck) more than annual weeds. Both types of vegetation also resulted in decreased leaf nitrogen, increased juice content, soluble solids, and titratable acid. Bermudagrass competition resulted in increased fruit size. Complete or partial weed control eliminated or reduced adverse effects of competitive vegetation on fruit production.
