Summary: Se realizo un experimento con la variedad de frijol Bountiful en Rincon del Cerro, Montevideo (Uruguay) para determinar los niveles optimos de fertilizacion. Con base en una revision de literatura, se hizo un estudio de los requerimientos nutricionales de la planta, fijacion simbiotica del N, fertilizacion con NPK, metodos de aplicacion, diferentes modelos de analisis economico y diseno experimentales. Se analizo el rendimiento y sus componentes. Los rendimientos no fueron tan altos como se esperaba, probablemente debido a las condiciones extremadamente secas durante el experimento. La unica respuesta significativa fue el N. Se dan posibles explicaciones. Los componentes que mas afectaron el rendimiento fueron el no. de vainas/planta y el peso de 100 semillas. Se presenta un analisis economico de los diferentes tratamientos con fertilizantes. (CIAT)Summary: An experiment was conducted with the bean variety Bountiful in Rincon del Cerro, Montevideo (Uruguay) to determine optimal levels of fertilization. Based on a literature review, a study was made of the plant's nutrient requirements, symbiotic fixation of N, NPK fertilization, methods of application, different models of economic analysis and experimental designs. Yield, as well as its components, were analyzed. Yields were not as high as expected, probably because of the extremely dry conditions during the experiment. The only significant response was to N. Possible explanations are given. The variables affecting yield most were the no. of pods/plant and the wt of 100 seeds. An economic analysis of the different fertilizer treatments is also given.
