Abstract: Management protocols to enhance flowering and fruit set of Julie mango were investigated at two locations in Trinidad over two seasons. The protocols tested represented the positive results of previous studies on flowering or yield of Julie mango conducted within the region over the past ten years. Treatments included potassium nitrate for flower induction, and the use of microelements, fungicide and insecticide for improved fruit set and post fruit-set protection. Potassium nitrate application resulted in significant increase of flowering in the second trial only. In the first trial, a combination of all treatments resulted in increased yield, as assessed at 14 weeks. In the second trial increased yield was found to be due to fungicide only. Despite the applications, the yield in the second trial was very poor. This leads to the conclusion that there were limitations other than nutrition, pests or disease that affected final yield.
