Rentabilidad económica de explotaciones agrarias de secano según tamaño y tipo de laboreo

Abstract

The objective of the present study was to assess, in semiarid conditions of central Spain, the economic feasibility of chisel ploughing and no-tillage compared to mouldboard ploughing for rainfed winter wheat and forage legume production on different farm sizes. A decision support system was used to solve for the least-cost machinery selection for each farm enterprise and tillage system considered. No differences were observed in either wheat or forage vetch crop yields averaged across several years, irrespective of the tillage system used. The economic performance was found to depend on the tillage system adopted and farm size.
