Evaluacion de dos cosechadoras de yuca
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 and M...

| description | 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 and M Mex 11) were planted on the flat. Harvester A left the roots totally exposed on the surface and partially removed the soil on them, while harvester B did not expose the roots totally. Root losses were greater than with manual harvesting and less than with harvester B; harvester A caused more root breakage. When comparing planting systems and densities, the proportion of roots left in the ground tended to be greater than in ridge planting at low densities and less than in cassava planted on the flat at a high density. The net working efficiency of harvester A was calculated at approx 0.2 ha/h, while that of harvester B was estimated at 0.5 ha/h. The overall damage for root breakage and bruising with harvester B was low, comparable to that of manual harvesting; that of harvester A being greater than. Harvester B was recommended for small farms while harvester A has potential for large-scale production. (CIAT) |

(CIAT) 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 22, CMC 84 y M Mex 11) en plano. La cosechadora A dejo las raices totalmente expuestas sobre la superficie y solto parcialmente el suelo que estaba adherido a ellas, mientras que la cosechadora B no expuso totalmente las raices. Las perdidas de raices fueron mayores con cosecha manual y menores con la cosechadora B; la cosechadora A ocasiono mas rompimiento de las raices. Al comparar los sistemas de siembra y las densidades, la proporcion de raices que quedo en el suelo tendio a ser mayor en la siembra en camellones a baja densidad y menor en la yuca que se sembro en plano y a alta densidad. La eficiencia neta de trabajo de la cosechadora A se calculo en aprox. 0,2 ha/h, en tanto que para la B se estimo en 0,5 ha/h. El dano global por rompimiento y pelado con la cosechadora B fue bajo y comparable con el de la cosecha manual; el de la cosechadora A fue mayor. Se recomienda la cosechadora B para pequenas fincas, mientras que la cosechadora A es un sistema potencial para produccion a gran escala.
