Abstract: 

The evaluation of energy efficiency and determining types and amounts of consumed energy could be assumed as a scientific method for stability and constancy of production in an agricultural ecosystem. In this paper we estimate and evaluate the consumed energy for agricultural ecosystem in Astan-E-Ghods-Razavis farms in Mashhad. The research was done according to the results of step by step operational and theoretical measurements of tillage, planting, cultivating and harvesting. To do this, we converted results (related to inputs and outputs) to equivalent consumed and generated energies to be able to calculate the efficiency of energy. The amount of consumed input energy and generated output energy (wheat seed) in irrigated farming was 7731553 (Kcal/ha) and 20517800 (Kcal/ha) in average. So energy efficiency (output/input) for seed, chaff and biological yield (seed + chaff) was 2.65, 2.14, and 4.8 in average. The evaluation of input energy showed that most of energy consumption was related to electricity energy consumption for irrigating that was about 41.5% of total consumed energy. After that, net consumed nitrogen by 17.75% and consumed fuel by 15.15% had second and third place in this ranking. In addition, human labor (biological energy) by 0.7%, herbicide by 0.49% and pesticide by 0.29% were the least energy consumer parts that with agronomic suitable management can reduce the consumption of other energies, so increasing in efficiency per unit area, generated energy or products without decreasing in quality of operations.
