Abstract : In Mexico, Manila is the most appreciated mango cultivar, in terms of both area and yield. However it has been poorly studied. This study was carried out for two years in trees older than 30 years, from which leaf samples were taken and climatic variables were evaluated. Growth, development and production variables were also assessed on a yearly basis in order to determine the interrelations of these parameters with the macro and micro nutrient content in the leaves during the vegetative and reproductive phases. The results indicated that in the vegetative phase and during flowering and fruiting, P was the most interactive although in a negative rather than in a positive manner, followed in importance by K, Mg and Fe. Fruit yield, on the other hand, was not related to nutrients but to some growth, dendrometric, and practically all the production variables. In the general correlation, P was the most interactive, being followed in importance by Fe, Mn, N, Mg, Ca, Cu, K and Zn; and yield was related only to some growth variables, but mostly to those of production parameters.
