Response to organic fertilization in mango cultivars: Manila, Tommy Atkins and Ataulfo
The objective was evaluating the response to mineral (230-0-300 and 230-0-0 g NPK tree-1) and organic: vermicompost, bokashi and chicken manure (5 and 10 t ha-1) fertilizers in soil nutrimental content (pH, MO, macro and micronutriments), trunk diameter, flowering, and yield of three mango cultivars...

| Sumario: | The objective was evaluating the response to mineral (230-0-300 and 230-0-0 g NPK tree-1) and organic: vermicompost, bokashi and chicken manure (5 and 10 t ha-1) fertilizers in soil nutrimental content (pH, MO, macro and micronutriments), trunk diameter, flowering, and yield of three mango cultivars: 'Manila', 'Tommy Atkins', and 'Ataulfo'. For soil variables were design completely random and other variables a split-plot in completely random. Differences between contents of N, K, Ca, Cu and Zn were showed in soil. Differences were showed between cultivars in trunk diameter. Flowering showed differences among cultivars and fertilizers. Regarding yield in 2010, only 'Tommy Atkins' fruits were harvested, showing differences between fertilizers and control. In 2011, were differences among cultivars and fertilizers, chicken manure and mineral fertilizers outperformed the control. In 2012, 'Tommy Atkins' outperformed 'Ataulfo'. It is concluded that chicken manure 10 t ha-1, were similar to nitrogen doses on soil contents of N, K, Cu and Zn; fertilizer do not have influence in the trunk diameter; on flowering and yield, bokashi and chicken manure 10 t ha-1, were similar to nitrogen doses. |
