ANALYSIS OF THE ECONOMIC EFFICIENCY IN FODDER PRODUCING
This paper aimed to present a study case concerning the analysis of the economic efficieny in corn silage producing based on gross margin and profitability threshold methods. Two corn yield levels were taken into account : V1 – 45 t /ha and V2 -55 t/ha, whose total production costs per surface unit were Euro 1,967 and, respectively, Euro 2,096. The V2 variant assures a higher economic efficiency as silage production in terms of net energy is higher per each paid Euro (42,83 MJ NE/Euro). As a conclusion, in fodder producing, despite that it has a negative value, gross margin allows the comparison between various types of forages based on its value per production unit in terms of net energy per unit of cultivated surface. Also, gross margin assures the comparison between various production intensities in the producing of the same fodder.
