Fertilization is a key practice to achieve an adequate yield and quality of coffee in Colombia. For this purpose, the local trade offers simple, bulk blends (BF), and compound fertilizers (CF) made of different technologies. This study aimed to evaluate the effect of different types of fertilizers on the yield and physical quality of coffee beans. In four localities of Colombian coffee zone, seven treatments were evaluated, which consisted of supplying macro and micronutrients to coffee crops during its reproductive stage, applying the next sources of fertilizers: 1). CF of traditional use (CF1), 2). CF2 from different technology of CF1, 3). CF2 + BF (K+Ca-B nitrate), 4). CF2 + BF (Ca-B nitrate), 5). BF-NPKMgS (Urea-DAP-KCl-Kieserite) + Zn + Ca nitrate (without B), 6). BF-NPKMgS + B + Ca, and 7). BF based on Soil Analysis (Ca, Zn, B) using NPKMg. The treatments did not affect the annual and cumulative production of coffee. Variations on yield among localities were associated with environmental conditions. The ratio coffee cherry/ dry coffee parchment had values of reference associated with good coffee quality, while the threshing performance factor was below 89.5% across all the treatments and localities evaluated. The results demonstrate the possibility of fertilizing effectively the coffee at the reproductive stage, applying the required nutrients and recommended doses, through compound fertilizer from different technologies or its nutritional equivalent using bulk blend, preserving the yield and the physical quality of coffee.
