| description | Results of research on soil fertility management for bean production in Uganda are explored. The occurrence and severity of soil fertility problems as constraints to bean production are examined and additional research needs are suggested. Results of trials conducted on research station and farmers' fields show that soil nutrition problems are major contraints in bean production. Yield response to applied N and P frequently occur. Application of K and lime result in increased yield in selected sites, but response to applied micro-elements are rare. Crop production in Uganda is concentrated on the more productive soils. Much of the potentially arable land is not in cultivation because of low soil fertility problems. Other areas are extensively cultivated, but with frequent fallow periods. Soil fertility problems can be expected to increase as crop production encroaches into marginal areas. (AS) |

(AS) Se examinan los resultados de investigaciones en manejo de la fertilidad del suelo para la produccion de frijol en Uganda y la presencia y severidad de los problemas de fertilidad del suelo como factores limitantes de la produccion de este cultivo. Se sugieren necesidades adicionales de investigacion. Los resultados de ensayos relaizados en estacion y en campos de agricultores indican que los principales limitantes de la produccion de frijol son los problemas de nutricion de los suelos. La respuesta de los rendimientos a la aplicacion de N y P es frecuente. Las aplicaciones de K y cal dan como resultado un aumento de los rendimientos en los sitios escogidos; sin embargo, es escasa la respuesta a la aplicacion de microelementos. La produccion de cultivos en Uganda se concentra en los suelos mas productivos. Muchas de las tierras potencialmente arables estan sin cultivar debido a problemas de baja fertilidad del suelo. Otras areas se cultivan en forma extensiva pero con periodos frecuentes de barbecho. Es de esperarse que los problemas de fertilidad del suelo se incrementen en cuanto la produccion de cultivos invada las areas marginales.
