Fertilización orgánica de banano y su relación con la severidad de la sigatoka negra mycosphaerella fijiensis m

The experiment was conducted at Finca La Rosita, Canton Province of El Oro Machala, Ecuador, from April 2007 to January 2008 and involved the planning of four doses of potassium fertilizer: 150 - 250-350-450, kg / ha / yr, randomly selected from organic sources, with nitrogen (N) 50 and phosphorus (P) 10 fixed, with ratios N / K: 1:3, 1:5, 1:7 and 1:9, which were explored to observe the response of black Sigatoka and fruit quality in the variety Grand Nain (AAA, Cavendish). The effects of four nutritional balance and its relationship to the severity of Black Sigatoka, has much to do with the proper performance of the plant work in organic plantations established so that thus the applied treatments are effective, so we can show that concentrations of potassium (K), in their various relationships planned for research, one can see a clear effect on the control of black sigatoka fungus, also reflected an increase in physiological activities of the plant productivity and fruit quality as shown . To determine the quality of the fruit is considered the long finger, as the soluble solids and the presence of pulp cream using a subjective scale. According to plan with four levels of fertilization was reached to have relations with 1:7 and 1:9, harvested fruit pulp to 12 weeks with firmness and consistency, without risks to export. The relations 1:7 and 1:9, this occurred control, productivity and fruit quality. ANOVA applied to the results for all treatments and study variables showed no significant values, so it could not perform the power test as (Duncan), to determine the statistical differences between treatments, but it was ascertained an analysis of each treatment averages given by the standard error.
