Fertilization is one of the main practices to increase coffee productivity in Colombia. This activity is done by applying the nutrients through the root zone; however, in specific climate and soils conditions, its effectiveness may be affected. In order to find strategies to improve the effectiveness of coffee fertilization, the foliar application of nutrients, as a complement to soil fertilization, was evaluated in four locations of the Colombian coffee region with different soils and climatic characteristics. The treatments were applied 60 and 90 days after flowering, and consisted of the foliar supply of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), boron (B) and the combinations P-N, K-N, Ca-N, Ca-B and N-P-K. Coffee cherries yield (cc), coffee cherry/dry parchment coffee ratio (cc/cps), threshing performance factor (FRT) and foliar absorption of nutrients were evaluated. Foliar fertilization from the evaluated nutrients, doses, seasons and fertilizer sources evaluated did not significantly improve cc yield or the grain physical quality (cc/cps and FRT). With the exception of B, none of the elements applied to the leaves increased its foliar content; the application of B increased its foliar levels above 40 mg kg-1, indicating that its application with the evaluated doses and sources allows correcting a nutritional deficiency without resulting in a toxicity or yield rises.
