How can one make money from mango production? Ricardo Tolentino, the acknowledged Mango King from Ilocos Norte, stresses the importance of providing mango trees with adequate fertilizers of the right kind. At the same time, you have to minimize the use of chemical pesticides to cut the cost of production.
The Mango King recalled that the mango rehabilitation program initiated by Gov. Imee Marcos a few years back had proven that adequate fertilizers can significantly increase fruit production.
For instance, the old mango trees in Ilocos Norte used to produce about 1,000 kilos per tree. Then all of a sudden, the yield went down to just 500 kilos. With just the application of complete fertilizer at five kilos per tree, the yield increased by 40 percent or an additional 200 kilos.
Now, based on his experience and observations, he recommends applying 6 kilos of processed organic fertilizer, 4 kilos of complete and 2 kilos of 0-0-60 (muriate of potash) per mature tree. It is also very important to apply the chemical fertilizers in the right place. As per his observation, the chemical fertilizers should be buried four to six inches deep around 1.5 meters from the trunk. He has observed that the root hairs are most plentiful in that area. Previously, the recommendation was to apply the fertilizer much farther from the trunk – within the far end covered by the canopy.
AT FLOWER INDUCTION – At the time of spraying the trees with flower inducer, Carding recommends the inclusion of insecticide and fungicide in the spray solution. By doing this, the emerging flowers will already be protected from insects and fungal diseases. By doing this, Carding said, you will only need to spray the trees three times against pests and diseases. This is much less than what many mango growers in Pangasinan are doing. In Pangasinan, the growers spray their trees as many as ten times against hoppers. And that is the reason why the insects have become immune to the pesticides in that province.
