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...
