    Abstract/Description
    Different nutritional deficiencies or toxicities may limit bean development and yield. N and P deficiencies are the most frequent, although deficiency of minor elements and Al/Mn toxicity can reduce yields considerably. Nutritional problems are usually diagnosed by soil and plant tissue analyses and the observation of symptoms produced by nutritional disorders. Optimum pH for bean production varies between 6.5-7.5; within these limits, the majority of the plant nutrients have their max availability. Color illustrations are given of the symptoms of plant deficiencies and toxicities. (CIAT)
     
    Diversas deficiencias o toxicidades nutricionales pueden limitar el desarrollo del frijol y su rendimiento. Las deficiencias de N y P son las mas frecuentes, aunque las de elementos menores y la toxicidad de Al y Mn pueden reducir considerablemente los rendimientos. Los problemas nutricionales se diagnostican mediante el analisis del suelo y el tejido vegetal, y la observacion de los sintomas producidos por desordenes nutricionales. El pH optimo para producir frijol fluctua entre 6,5-7,5; dentro de estos limites, la mayoria de los elementos nutritivos de la planta presentan su max disponibilidad. Se presentan ilustraciones en color de los sintomas de deficiencia o toxicidad en las plantas. (CIAT)
