Dense plantation do not control banana black-sigatoka

Many publications show that plantations of high density of bananas decrease the severity of black-sigatoka (Mycosphaerella fijiensis). To test this hypothesis it was instaled an experiment with five treatments and four repetitions. The treatments were density plant of 1.600, 2.000, 2.400, 2.800 e 3.200 plant.ha-1. The cultivar planted was D'Angola and each plot had fixed 2.000 m², the number of plants in each plot changed in accordance with the treatment tested. The plots were divided in four subplots of 500 m² where 15 plants located in the center were measured. The evaluation of severity was carried out in the leaf number ten during the flowering period. It was also evaluated the numbers of viable leaves, height, diameter and weight of production (banch, bunches and fruits). The analyses did not show effect of high density in the parameter measured and it was conclued that the treatments tested had not control black-sigatoka.
