Identification and Prioritization of the Effects of Chemical Inputs on Environmental Indicators of Pistachio Crop in Kerman Province

Today, paying attention to environmental indicators is considered as one of the most important approaches to agricultural production. For this purpose, it is necessary to identify and prioritize, measure the effect, the intensity of sensitivity of environmental indicators to changes in chemical inputs over time. The aim of this study is to identify and prioritize chemical inputs on environmental indicators of pistachio in Kerman province. The statistical population of the study included veteran experts of agricultural jihad in Kerman province. The sample consisted of 50 specialists who were purposefully selected. To prioritize the environmental indicators of chemical inputs used in pistachio orchards, the fuzzy hierarchical analysis process method (Chang method) was used. Findings of the study showed that soil contamination due to the use of chemical inputs has the highest priority. Water pollution caused by chemical inputs is in the second place. Air pollution caused by the use of chemical inputs is in the third degree. Exports of chemical inputs and risk aversion in the use of chemical fertilizers are the last ranking. It can be suggested that the use of organic fertilizers along with biological and natural methods of pest control in pistachio orchards can be alternative options related to environmental pollution.
