Research in bean economics includes production, marketing and consumption, and policy studies. Production research focuses on 2 mutually reinforcing themes: (1) assessment of the spread of new var. recently released to farmers by national programs; and (2) assessment of farmers' current productio...
La investigacion en economia de frijol incluye estudios en produccion, mercadeo, consumo y politicas. La investigacion en produccion se enfoca en 2 esquemas que se refuerzan mutuamente: 1) evaluacion de la diseminacion de las nuevas var. recientemente liberadas a los agricultores por los programa...

Two trials were conducted to evaluate the efficiency of a commercial cassava harvester (A) and a harvesting implement (B): (1) the var. Chiroza (difficult, to harvest) was planted using 3 systems (beds, ridges and on the flat) at different densities and (2) three cassava var. (M Col 22, CMC 84 an...
Con el fin de evaluar la eficiencia de una cosechadora comercial de yuca (A) y un implemento (B), se establecieron 2 ensayos: 1) se sembro la var. Chiroza (dificil de cosechar) en 3 sistemas de siembra (camas, camellones y en plano) con diferentes densidades. 2) Se sembraron 3 var. de yuca (M Col...
