Methodological considerations of irrigation energetics

Abstract: Methods are described to assess the total energy inputs for the irrigation of different crops. Energy yields as main products such as grain and as total biomass have been worked out. This methodology is illustrated with data from a sample farm growing wheat, paddy, berseem, sorghum fodder, and sugarcane. Energy inputs have been computed for the primary fuels used to generate electricity for pumping water. Fixed inputs embodied in materials, equipment and labor have been amortized for their expected lifetime. Compared to the energy yields in the main products, inputs in irrigation involved 6.8% for sorghum fodder, 13.9% for berseem, 15.2% for wheat, 15.9% for sugarcane, and 37.0% for rice.
