Aporque alto y continuo
(Honduras)
Description
Se realiza un aporque alto en el maíz con la segunda limpia
Se acumula con el azadón una barrera de tierra de mínimo unos 25 cm de altura al pie de las plantas. Esta barrera es continua y en contra de la pendiente, por lo que se requiere la siembra en contorno (HON1). La práctica se realiza unos tres meses después de la siembra del maíz. El aporque alto y continuo tiene dos objetivos: de reducir la erosión (reducción de la pendiente, cosecha de sedimento, abono y agua) y de reforzar la planta (se tapan las raices de nuevo). Es una práctica que se hace a mano con el azadón por lo que requiere bastante mano de obra, pero se combina con la limpia. Hay que hacer la práctica en cada ciclo y sólo se realiza en el cultivo de maíz.

Establishment and maintenance: activities, inputs and costs
Calculation of inputs and costs
- Costs are calculated:
- Currency used for cost calculation: lempira
- Exchange rate (to USD): 1 USD = 13.0 lempira
- Average wage cost of hired labour per day: 1.40
Most important factors affecting the costs
El factor determinante es la mano de obra necesaria para establecer los surcos y realizar el aporque cada ciclo.
Establishment activities
-
aporque (Timing/ frequency: tres meses después de la siembra)
Maintenance activities
-
siembra en contorno (Timing/ frequency: época de siembra / cada ciclo (año))
-
