Mango (cv. Kensington Pride) is a major crop in tropical northern Australia, but flowering and fruiting of this cultivar is highly variable. Field experiments evaluated cincturing and chemical treatments as means of improving mango productivity. The chemical treatment was a morphactin formulation (MF) and was introduced to the trees by either painting onto the bark (MFpaint) or soaking twine in MF before tying it into a trunk cincture (MFtwine). Vegetative growth, flowering and fruiting were compared to trees which had a cincture (Cincture), twine without MF (Twine) or paclobutrazol treatment (5.0 g active ingredient). Twine, MFtwine and MFpaint had a positive effect on flowering and fruiting. These trees had earlier, more intense flowering, produced early (September) fruit (up to about 4 fold increase) and high total yield (up to about 2 fold increase). In some cases vegetative growth was reduced by 50-60 percent. Responses to paclobutrazol were less than to Twine, MFtwine or MFpaint.
