THE INFLUENCE OF OXIHUMATE ON NEMATODE CONTROL AND ON YIELD (MUSA AAA, CAVENDISH SUB-GROUP)
The scope of this study was to investigate the possibility of using oxihumates as an environmentally friendly nematode control measure and whether improved crop yield and quality of banana could be obtained. This coal-derived product is known to exhibit properties of soil amelioration, growth stimulation, enhancement of crop yield, and restoration of the soil biodiversity. Trials with oxihumates on banana started at Kiepersol during March 1993 and treatments were an untreated control, phenamiphos, oxihumate in granular form, oxihumate sprayed on the leaves in a liquid form and a combination of both oxihumate treatments. Nematode samples were taken 3 times a year and yield data were collected throughout the trial. Results indicate that oxihumates definitely had a beneficial influence on the soil structure and biofauna. Water retention potential was 44% higher in the oxihumate treated soil. The direct influence of oxihumates in Radopholus similis was probably insignificant, but the product could contribute by rendering the plant more resistant to nematode attacks and it becomes stronger and healthier. Yield data showed no statistical differences between the treatments.
