The main obstacle for the generalized use of live posts of gliricidia in the production of passion fruit is the profuse crown growth in gliricidia, which requires frequent lopping. On a 1.5 year-old plantation of passion fruit in Dumbarton, St. Vincent, three treatments were used to control branch development in the gliricidia posts. The two nontraditional treatments, application of 25 cm3 of CULT AR (25% paclobutrazol) and girdling of the posts, resulted in significant reduction of branch production in comparison with the control treatment which consisted of lopping only. Posts treated with CULT AR showed the most drastic reductions in branch growth. No effect of the treatments on post mortality was observed. The new tested treatments have a potential to significantly increase the cost-effectiveness of passion fruit cultivation in the Caribbean.
