Purpose: Coffee is a highly valued commodity and demands high nutritional inputs for its vegetative and reproductive development. Different sources of fertilizers are used to supply the nutritional needs of the plant. The objective of the present study was to evaluate the response of different sources and doses of special fertilizers compared to conventional mineral fertilizers in coffee plants in two consecutive crop seasons. Method: A 4×4 factorial scheme was implemented with four fertilizers [conventional mineral, mineral with polymer, organomineral with cellulosic residue (OM-CR), organomineral with sugarcane filter cake (OM-FC)] and four doses (50, 75, 100, and 125% of the recommended dose). Coffee plant growth was evaluated: plant height, canopy diameter, growth of plagiotropic branches, and chlorophyll content. Nutrient contents in the soil and leaves, as well as coffee bean productivity, were also analyzed. Results: In biometric data, mineral and organomineral fertilizers showed responses that were equivalent to or superior to those of the control, even when using reduced OMF doses. For leaf N, P, and K content and soil P and K contents, the organomineral fertilizers performed better than conventional mineral fertilizers, especially in the second crop season. There were no significant differences among the fertilizers and doses for coffee bean productivity. Conclusion: The organomineral fertilizers, regardless of the dose, showed comparable or improved resultscompared to the conventional mineral fertilizer for the plant growth variables, potentially replacing traditional mineral fertilizers in the nutritional management of coffee crops. These results are the first report on coffee production using special fertilizers on two consecutive harvests. Highlights: · Organomineral fertilizers are under development, and consistent studies are needed in coffee crops. · Organomineral fertilizers on coffee development present superior growth responses at reduced doses. · Coffee leaf N, P, K and soil P, K responded more to organomineral fertilizers in the second season. · No significant differences were detected among fertilizers and doses for coffee bean productivity. · Organominerals can replace mineral fertilizers in the nutritional management of coffee crops.
