Abstract: The objective of this research was to estimate the banana population density (Musa sp.) in areas with at least 10 years of production on the north coast of Santa Catarina. The banana fields were grouped proportionally to sun exposure (flat, south face and north face), and sampled by the probabilistic method with binomial distribution and 5% error. The density was obtained by the “random circle” method; the age by interviews; the bunches yield by weight; the number of hands and fruit diameter; and productivity in three classes of densities: until 1,550; from 1,550 to 1,650 and above 1,650 plants ha-1. There was no significant difference between the densities in the areas in different conditions of sun exposure and / or age of the crop. Areas with 1,550 to 1,650 plants ha-1 had the best yield and productivity. It was concluded that: (i) 18% of the areas are with a density of 1,550 to 1,650 plants ha-1 (recommended), 43% above and 39% below; (ii) densities above 1,650 and below 1,550 plants ha-1 decrease the quality and / or productivity, therefore it is recommended to renewal; (iii) the change in density can be related to errors in the desuckering and / or loss of plants for various reasons, cumulative over time.
