Abstract: One of the new methods for evaluate the exergy-energy and share of agricultural productions, is cumulative exergy consumption (CEXC) analysis. CExC approach ensures that crop production processes can evaluate in the context of sustainable management and conservation of resources. In this research, wheat production processes (dry and wet) was investigated by CEXC approach. Cumulative degree of perfection (CDP) calculated 2.9 and 6.48 for wet and dry wheat production, respectively. The Renewability Indicator (RI) in this research were obtained 0.65 and 0.84 for wet and dry wheat production, respectively. In this research, electricity and diesel fuel had the highest consumption in all wheat production process. For a new case, it was assumed that the electricity and diesel fuel are produced by solar energy and biodiesel, respectively. In the new case, the CDP factor of wet and dry wheat production were 16.70 and 13.92 and RI values were 0.94 and 0.92, respectively.
