Abstract
Introduction: Life cycle assessment is a well-known and accurate solution for comparing the environmental effects of various activities, including the management of agricultural systems. This study was reviewed during the crop years 1390-1396. For this purpose, among 260 people in the statistical population, the sample size was determined using the Cochran's formula 152 people.
Materials and Methods: the relevant information was collected through interviews with farmers, the Ministry of Jihad for Agriculture and relevant organizations. In order to analyze the environmental effects, the ISO 14040 method in four steps and six groups of global warming, acidity, depletion of fossil resources, depletion of water resources, depletion of phosphate resources and depletion of potassium resources per functional unit equivalent to one ton of lettuce, Cabbage , and bell peppers were examined..
Results and Discussion: For this purpose, the highest share of environmental index and resource depletion was related to lettuce and allspice products with values of 0.172 and 0.578, respectively. The groups of the effect of acidity on lettuce and depletion of phosphate sources in cayenne pepper with values of 0.001 and 0.424, respectively, had the highest potential for environmental damage. Among all three studied products, lettuce has the highest value in the environmental index with a value of 0.1720, which indicates the greatest impact on the environment, while in terms of depletion index of bell peppers with a value of 0/5786 has the most effect.
Conclusion: Resource depletion impact groups are a challenge for the future, while environmental impact impact groups are visible in a relatively shorter period of time. Excessive increase of nitrogen fertilizers in summer production farms causes the release of pollutants into the environment and increases the potential for acidification. Therefore, by using low-input and ecological principles, including the use of organic fertilizers, plant residues and importers of nitrogen-fixing plants as a solution to reduce the environmental consequences of summer production in Dezful can be considered.
