Energy and Economic Analysis of a Double Cropping System for Biomass Production under Two Different Spanish Conditions

M. Aranzazu Del Val, E. Maletta & J.E. Carrasco
In order to achieve several synergies and improve economic efficiencies, food/feed double cropping systems have been extensively studied in traditional forage management and cereal­oil crops. Nevertheless, double cropping energy systems have not been studied yet in Spain. Cropping, mowing, drying and baling a C3 annual grass or winter cereal under rainfed conditions (even with scarce irrigation support), and immediately direct sowing a C4 annual grass like sorghum using irrigation during the spring/summer season might improve...
