Abstract

Recently evaluation of input, output and global warming potential (GWP) have been an extension in sciences of agricultural. For this study, 95 farmers were selected for rained Wheat in the semi-salty farm in the north of Golestan Province (Aqal City).The data including (machines, seeds, fertilizers, fuel, and pesticides) were collected by questioner. Then fuel, input and output energy, energy evaluation indexes and global warming potential (kg CO 2 /ha -1 ) were calculated. Results showed that the most direct input energy from fuel in rained Wheat was 38.8 percent. Also, the highest indirect input energy in rainfed Wheat was 31.3 that related to fertilizers. The ratio of output to input energy in rainfed Wheat was calculate 5.01. The amount of GWP was 943.5 (kg CO 2 /ha -1 ) in rainfed Wheat. The highest GWP was related to nitrogen fertilizer and fuel consumption. For Wheat, the consumption of fuel and fertilizer constitute the high percent of energy consumption and greenhouse gas emissions. So that, the use of devices that reduce fuel consumption is recommended, also need for research and investigation on crop rotation and nitrogen fixation plants were revealed.
