Abstract : Studies were conducted in the Dominican Republic during two years on adult 'Keitt' mango (Mangifera indica) fields to examine the long-term effect of chemical and organic fertilization programs on marketable fruit yield. The treatments were: 1.8 kg 15-15-15 (N-P-K)/tree, once a year; 1.1 kg 15-15-15/tree, twice a year; 1.4 kg 15-15-15/tree, once a year; 1.8 kg 15-15-15/tree, once a year, plus 13.6 kg compost/tree; 1.1 kg 15-15-15/tree, twice a year, plus 13.6 kg compost/tree; and 1.4 kg 15-15-15/tree, once a year, plus 13.6 kg compost/tree. The results indicate that the application of 1.8 kg 15-15-15/tree, once a year, plus 13.6 kg compost/tree and 1.3 kg 15-15-15/tree, twice a year, plus 13.6 kg compost/tree improved marketable fruit number during both harvest years. The addition of compost for two years increased fruit number by averages of 17 and 24% in comparison with the same treatments without compost.
