Abstract :

Agriculture is an energy conversion process. In this process the sun's light energy, product by fossil fuels and electricity, food and fiber becomes humanity. Overall, the present study was to evaluate the energy and economic indicators orange orchards city of Surrey and offering appropriate solutions to improve and enhance its performance was. To collect data and information used in this study, two methods were used for athletics and documents. For data -analysis using a linear regression model was used. The results showed that the total energy required to produce an orange 28237.294 MJ ha-1. Energy efficiency, energy efficiency and pureenergy, respectively, 1.59, 0.83 and 16643.296 MJ/ kg , Kg/Mj and Mj/ha-1 respectively. The greater share of renewable energy production to renewable energy accounted for. The Total costs of production of oranges obtained from planting until after 8438866.7 Toman/ ha-1 productivity and profit (benefit to cost ratio) was 1.68.
