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...
During 1981 the analysis of the potential adoption and impact of improved cassava production technology was continued at various levels and included: farm-level studies of the profitability of improved technology and constraints to adoption; analysis of costs of processing and marketing; and rese...
