| Abstract:
The main limiting problem of papaya cultivation in Mexico is the papaya ringspot virus (PRV). This disease reduces yield and fruit quality. In looking for control alternative measures several methods have been tested. Up to now the more effective one has resulted a combination of integrated management practices. The objectivs of this study were: to determine fruit set, to register PRV incidence and to evaluate fruit yield. Treatments tested were: integrated management practices (IMP), intensive management (InM) and control (C). Papaya plants responded best to IMP with the greatest: fruit set (19 fruits/plant); plant height (2.15 m) and stem diameter (8.02 cm). Plants in such treatment showed a delay on the onset of PRV during the first five months of plant growth; this was shown also as the greatest fruit yield (28.5 ton ha-1) as compared to the control treatment (17.8 ton ha-1) | |
