Abstract : A study was conducted to test the effects of the application of the biofertilizer Maya Magic (MM; containing soil microorganisms), clearing and bagging on some quality characteristics of mango cv. Kent. In full blossoming and first auxiliary irrigation, 1 litre MM/ha diluted in 100 litres of water was applied to the soil, applying one litre of dilute MM per tree, in the mean third of the drop dispensing area. During fruit fastening, bagging of 50 fruits per tree was carried out. Clearing was performed leaving 1-2 fruits per panicle, 4-5 intermittent shakings per branch were administered and the axes of fruitless inflorescence were eliminated. Upon the physiological ripening of the fruits, the lowest total soluble solids content (7.8°brix) occurred when 2 fruits per panicle were left. The highest total soluble solids content (10.4°brix) was recorded when MM was applied to conventional control fruits. The highest resistance (8.3 pounds) to penetration of the fruit was achieved by bagging the conventional control fruits. The lowest resistance (6.1 pounds) to penetration of the fruit was obtained in the conventional control fruits treated with MM. The weight per fruit was lowest (383 g) when 2 bagged fruits per panicle were left, while it was highest (452 g) when one fruit per panicle was left and MM was applied to the soil.
