Summary: Knowledge about dry matter (DM) accumulation in berryand its main parts (bean and husk) is crucial to understand the dynamics of the fruit throughout the maturation process and to adjust the harvesting time to achieve a higher grain yield, while knowledge related to nutrient accumulation provides important information for better fertilizer management. Therefore, the aim of this study was to evaluate the effect of the maturation process on the accumulation of dry matter, macro, and micronutrients in fruit, bean, and husk of six genotypes of Coffea canephora. The study was conducted in an experimental plantation at the UFES campus, São Mateus. Fruit samples were collected every two weeks, starting at 33 weeks after flowering, until the complete maturation of the six genotypes, totaling nine collection dates (periods), with the last at 49 WAF. The rate of DM accumulation was initially higher for the fruit and bean, and later for the husk. Secondorderpolynomial regressions were fitted for DM accumulation in the fruit, bean, and husk over time. DM accumulation in the fruit, bean, and husk increased as fruit maturation progressed, reaching the highest values in the final stages of red berries. The nutrient accumulation data were subjected to two-way analysis of variance (ANOVA). It was found that maturation influences the concentration and accumulation of nutrients in the beans, husk, and fruits. In general, the highest concentrations were observed in fully ripe fruits.
