Environmental crises and resource depletion have adversely affected the food security around the world. Food security in the future can be guaranteed by sustainable agriculture that respects the environment. So, it is necessary to decrease the energy consumption of resources for agricultural productions to achieve the maximum sustainability. For agricultural productions, environmental and energy issues are completely interrelated, and a comprehensive evaluation is necessary to manage them in all productions. In this study, energy, environmental, and economic indicators in cantaloupe production were studied. The studied energy indices included energy efficiency, energy productivity, net energy gain, and energy intensity. Life cycle method based on ISO 14040 standard was used to evaluate the environmental impacts. This method includes goal statement, identification of inputs and outputs, and a system for assessing and interpreting the environmental impacts of various agricultural productions. Also, for economic analysis, the average prices of inputs and outputs and also net return (NR), gross return (GR), and profit-to-cost ratio were used. The results showed that nitrogen fertilizer (32.28%) and diesel fuel (30.52%) had the highest and cantaloupe seeds (0.39%), and oil consumption in tractor engines (0.43%) had the lowest share of energy consumption, respectively. Energy efficiency, energy productivity, energy intensity, and net energy gain were estimated 0.56, 0.70 kg MJ −1 , 1.41 MJ kg −1 , and − 11,775.86 MJ ha −1 , respectively. The results of the present status of environmental impacts showed that the most effective factor in climate change is direct emissions from the diesel fuel. Also, indirect emissions from phosphorus and urea fertilizers had the highest effect on ecosystem quality. Various machine operations such as primary and secondary plowing, spraying, and transportation were the main causes of high diesel fuel consumption. Economic analysis showed that the profit-to-cost ratio and the productivity values were calculated about 1.6 and 7.27, respectively, which means that for every dollar spent in cantaloupe farms, it produced 7.27 kg of cantaloupe production. The variable costs were estimated at 1154.5 and fixed cost was 1487 $ha −1 . Among the variable costs, transportation and fuel costs were the highest with 64.3%. Decreasing the diesel fuel consumption by using appropriate farm management methods and using the reduce tillage methods can play an effective role in reducing the consumption of this input and improving the energy, environmental, and economic indicators in cantaloupe production.

“…Energy requirements in agriculture are divided into four groups: direct and indirect, non‐renewable and renewable. Direct energy is required to perform various tasks related to crop production processes such as land preparation, irrigation, inter culture, threshing, harvesting, and transportation of agricultural inputs and farm produce 2 . Nonrenewable energy includes diesel, chemicals, fertilizers and machinery, and renewable energy consists of human labor, seeds, and manure 2 .…”

“…The energy input for agricultural production has been identified as one of the crucial and important factors affecting the sustainable production of agri‐food products. On the other hand, considering the importance and necessity of management and agricultural economy, this factor is considered as a sufficient condition for production 2 . Increased production and reduced costs are considered as one of the main objectives of production units.…”

Technical management of agricultural units plays an important role in increasing the yield, energy efficiency, and decreasing the production costs. Based on that, the present study aimed to evaluate and optimize the technical and economic efficiency in Saffron farms in the 2019-20 cropping season in Iran. Required data were collected from 70 Saffron farms through interviews and questionnaires and were analyzed and compared using two optimization methods including data envelopment analysis (DEA), and multi-objective genetic algorithm (MOGA). Based on the results related to the energy section, the total energy input was obtained as 43,578 MJ ha À1 before any optimization, while it was determined as 36,033 and 36,910 MJ ha À1 after optimization using DEA, and MOGA, respectively. Also DEA and MOGA methods improved the energy ratio index (ER) (0.002) by 50, and 159%, respectively. Results related to the economic section showed that the total production costs were mitigated from 1260 $ ha À1 to 863.5 and 1069 $ ha À1 after optimization by DEA, and MOGA, respectively. After optimization of revenue (using MOGA method), and total costs (using MOGA, and DEA), the benefit cost ratio index was improved from 1.43 to 2.09 (using DEA), and 3.3 (using MOGA). Consequently, MOGA optimization method showed better results compared to DEA in both energy and economic sections.

“…Environmental pollutions, such as contamination with heavy metals, can affect the quality and safety of vegetables and herbs, known to be the most widely used plants in daily life ( Singh & Kumar, 2006 ). Onion (Allium cepa) is a widely used vegetable in the world, a monocotyledon plant belonging to Liliaceae family ( Mobli & Aslani, 2018 ), whose native and exotic breed genotypes are cultivated annually in Iran mainly ( Elhami et al, 2021 ). The research of onion epidemiology shows that the onion's cultivation areas in the world and Iran are 3451941, 57112 ha, respectively, which is in the second place following the tomato ( Ansari, 2007 ).…”
