Industrialization of todays societies, resulted in increased use of machinery and excessive use of fertilizers and chemical pesticides in agriculture. Life cycle assessment is one of the environmental assessment methods that is used to assess processes, products and services. Life cycle assessment method in this study is used to evaluate the environmental effects of bean production with sprinkler and flood irrigation methods in the crop year of 2016-2017 using the effects of global warming, acidification, land euotrophication, depletion of fossil, phosphate and water resources exploited in Yasuj city. The results showed that the final index of the three groups of environmental impact factors (global warming, acidification and land euotrophication) in rainfed more than flood farming and the indices of the three groups of resource depletion effects (fossil, phosphate and water depletions in both croppimg system. The environmental indices for sprinkler, flooding and flood irrigations were 0.634, 0.513, 1.14 and 2.26 respectively. Elimination of unnecessary operations in the planting process and reduction of fuel consumption, irrigation in the last hours and the beginning of the day when evaporation is low, the use of biological methods to remove pests and attention to general recommendations for chemical fertilizers can be effective in reducing environmental effects.
