Resumo: | ABSTRACT: Defoliation caused by Black Sigatoka in yield and quality of banana 'Nanica' was stimulated in this study. A completely randomized 2x8 factorial design with six repetitions was used, in which period of bunch formation and number of leaves at flowering were established as factors. Plants for defoliation were selected on 04/05/2013 (Period 1), and on 07/01/2014 (Period 2). Six to to 13 leaves remained per plant by removing those with more than 50% of blade with injury or senescence. More appropriate climatic conditions before and after flowering, promoted greater mass accumulation in the bunch in Period 2. The increased number of leaves at flowering increased the length of the fruit and the mass of 4th hand, as well as the bunch mass and postharvest period. Defoliation is suggested only for non-functional leaves as well as the maintenance of at least 10 leaves per plant, independent of the period of bunch formation. |
