Experimental work was conducted at the Adjuntas Substation to determine the effect of frequency of application of two fertilizer levels on coffee grown both in full sunlight (unshaded) and under partial shade, the latter provided by trees of Inga vera Wild., planted 24 feet apart. The partial shade was estimated at 40 percent. The two formulations, 100-75-200 and 200-75-400 pounds per acre of nitrogen, phosphorus and potassium, respectively, were applied in one, two, four, and six applications per acre per year, and later evaluated. The combined statistical analysis of five experimental crops of coffee grown in full sunlight revealed that higher yields were obtained from the 200-75-400-pound formulation when applied in one, two, and six app...
