This study aimed to evaluate physico-chemical properties of guava fruits, ‘Paen Srithong’ and ‘Kim Ju’, from organic and conventional cultivation Systems. Two nearby orchards were selected for the study. Soil chemical attributes, physical properties of guava fruits: weight, density, sphericity, total soluble solids and mechanical testing and chemical properties: ascorbic acid and pectin contents were analysed. The result showed that the organic orchard contained higher levels of soil organic matter, nitrogen, phosphorus and potassium than the conventional orchard. The organic fruits from both cultivars exhibited less density, higher ascorbic acid and higher flesh firmness than the conventional cultivated fruits. ‘Paen Srithong’ cultivar from organic cultivation system exhibited additional significant differences in bigger size and higher contents in TSS and pectin than the conventional cultivated fruits. This confirmation supports positive consumer perceptions on organic guava fruits. It is very useful for promoting the quality of organic guava fruit and enhancing sale.
