Sustainable development in agricultural production is an issue of growing concern. An energy-use pattern analysis is proposed for providing parameters for estimating agricultural sustainability. Since sustainability has to be assessed over generations, the current study examines the energy use pattern of 21 field crops in Iranian agronomy for the period of 1981-2005. Total output energy (energy production), output energy per unit of area, energy per unit of weight and output energy per capita were the indices calculated and analyzed. It was found that the total output energy, total output energy per hectare and output energy per capita grew with a rate of 31.83 PJyr , 2.35 GJyr and 0.25 GJyr respectively reaching the values of 11 1
