During part of the dry season in 1996 (November to December), surveys were made for incidence of root and stem rot in 99 fields of cassava (Manihot esculenta Crantz) randomly selected between latitudes 6°36′N and 7°49′N in Benin (79 fields) and Nigeria (20 fields). Root rot was observed in 65 fie...

Se discuten varios conceptos relativos al mejoramiento de leguminosas forrajeras y a su adaptacion a suelos acidos de baja fertilidad. Se observa que es raro que un ecotipo nativo selecionado ofrezca todas las caracteristicas requeridas para praderas de pastoreo. Los objetivos del mejoramiento de...

The process of selection in climbing bean improvement should be conducted with maize in association due to the high cost of sole cropping with stakes or with a trellis system. The relation between yields of beans and maize is negative and the regression coefficient is normally between -1 and -2. ...
