Diseases of the coffee plant can be effectively managed via well-balanced nutrition. This study assessed the effect of nitrogen and potassium fertilizers on the intensity of coffee (Coffea arabica) rust (Hemileia vastatrix) under greenhouse conditions. The susceptible cultivar New World 376/4 was used as the test species. Treatments included five N rates (3, 7, 11, 15 and 19 mmol L−1) with five K rates (3, 5, 7, 9 and 11 mmol L−1) in a 5 × 5 factorial design, for a total of 25 treatments and… Expand
