Abstract
The National Academy of Sciences identified a large number of "underexploited" tropical food plants in the 1970s which should be more widely introduced. However, it is very difficult to obtain seed, especially if you are a development worker rather than a scientist. ECHO has developed a "working seedbank" which sends small packets of these seeds for trial at no cost to those working with small farmers as well as to the scientific community. This slide presentation will feature many of these less common plants, as well as a technique of shallow beds suitable for rooftop gardening. Our various services to those working with small farms in the tropics will be briefly described. ----- En los anos 70, la National Academy of Sciences (Academia estadounidense de ciencias) identific6 muchas plantas tropicales alimenticias "sub-explotadas" que deberian ser cultivados de manera mas amplia. Sin embargo, es muy dificil olbtener semillas, sobre todo si uno es asistente de desarrollo y no cientifico. Por eso, ECHO ha elaborado un "banco de sernillas" que envia paquetitos "prueba" gratuitos de estas semillas tanto a los que trabajan con pequeiios agricultores como a la comunidad cientif'ica. Esta presentacion de diapositivas mostrara muchas de estas plantas menos conocidas, asf como una tecnica que utiliza los sernilleros poco profundos y que conviene muy bien a la jardinerla en la azotea, Se describe brevemente los servicios que prestarnos a los que trabajan en pequeiias fincas tropicales.
