dc.descriptionA set of four experiments with increasing levels of the three main plant nutrients and liming were established in two lateritic soils at two locations in the coffee-growing area of Puerto Rico. Two coffee cultivars were used in the experiments. The results obtained can be summarized as follows: 1. Nitrogen levels significantly affected coffee yields of the Puerto Rico cultivar in a Catalina clay at Maricao grown under shade. 2. Phosphorus and potassium did not significantly affect the yields of these coffee cultivars at the two locations. 3. Liming did not significantly affect the yields.en-US
dc.descriptionUna serie de cuatro experimentos con niveles incrementados de los tres nutrimentos de plantas principales se estableció en dos suelos lateríticos en dos localidades de la zona cafetalera de Puerto Rico. Se usaron dos tipos de café, Puerto Rico y Columnaris, en estos experimentos. Pueden resumirse los resultados como sigue: 1. Los niveles de nitrógeno afectaron significativamente los rendimientos de café del tipo Puerto Rico en un suelo Catalina arcilloso, en Maricao, bajo sombra. 2. El fósforo y el potasio no afectaron significativamente los rendimientos de ambos tipos de café en las dos localidades. 3. La aplicación de cal no afectó significativamente los rendimientos.es-ES
