Intercropping of Maçã and Prata Zulu banana cultivars for the cultural management of black Sigatoka
Abstract
In this study, we assessed the effect of intercrop planting of Maçã and Prata Zulu banana cultivars in the reduction of black Sigatoka severity and in the productivity of the Maçã cultivar. The treatments used were a combination of 5, 10, 15, 20 and 25% of plants of the Maçã cultivar distributed in plots with 95, 90, 85, 80 and 75% of plants of the Prata Zulu cultivar. Four months after planting, 20 leaves infected with black Sigatoka were distributed at each plot of 200 plants as a source of inoculum. The plots were separated by strips of secondary forest approximately 20 m wide and 15 m high. Each plot was divided in four subplots. Severity evaluation was performed in leaf number 10 during the flowering period. The number of viable leaves and the weight of production (bunches, hands and fruits) were also assessed. The statistical analyses did not show differences between the treatments used. Intercrop planting was not effective in reducing the severity of black Sigatoka in the Maçã cultivar and the yield was similar to that observed in monocultures.Downloads
