Abstract
El sistema de “frijol tapado” en la zona de Acosta, Costa Rica, se describe con base en observaciones en el campo y encuestas con agricultores. Se efectuó una evaluación agroeconómica del comportamiento de cultivares criollos y dos cultivares mejorados (Brunca e ICA Pijao) bajo este sistema. Se estudió el hábito de crecimiento y características del grano de los cultivares criollos. Los cultivares criollos dieron mayor rendimiento que los mejorados. En todos los cultivares se observó una reducción del 58% del número de plantas cosechadas respecto a las brotadas. Se obtuvo un retorna económica del 51,8% del costo familiar con los cultivares criollos, pero con los mejorados, el retorno económico fue negativo.
The description for “Tapado” bean planting system was based on field observations and farmers’ interviews from the zone of Acosta, Costa Rica. An agro-economic evaluation was conducted on the performance under this planting system for local cultivars and two improved cultivars (Brunca and ICA Pijao), from August through December, 1983. The growth habit and grain characteristics of the local cultivars were analyzed. The local cultivars showed higher yields over the improved ones. All the cultivars had a 58% reduction of harvested plants with respect to the number of seedlings. The local cultivars produced an economic return of 58% the production costs, but it was negative, for the cultivars.
