The research utilizes a combination of K-means clustering and a weighted Recency, Frequency, Monetary (RFM) model, and ordinal logistic regression to analyze customer behavior. Using real transaction data from 9,014 customers alongside questionnaire responses, the analysis categorizes customers into four distinct groups: very loyal, loyal, at-risk, and disloyal. The weighted RFM model indicates that recency is the most significant predictor of loyalty. Further, the ordinal logistic regression identifies several key factors influencing loyalty: age, marital status, income level, perceived food quality, preference for modern stores, and brand image. These all have positive effect on loyalty; on the contrary, the importance of price and a preference for packaging-free products negatively impact loyalty. These findings provide actionable insights for retail managers, enabling them to develop cluster-specific strategies that enhance customer loyalty and strengthen competitiveness in Iran’s dynamic retail sector.<br><br><br>https://jast.modares.ac.ir/article_16865_414187419105b06734cd36adead79115.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Building Climate Resilience: Competency-Based Training Needs Assessment of Extension Workers in Pakistan4935041686210.48311/jast.2026.16862ENSyed Mufeed HadiNaqviDepartment of Agricultural Extension, Education and Communication, The University of Agriculture, Peshawar, Pakistan.0009-0000-3885-5387RaheelSaqibDepartment of Agricultural Extension, Education and Communication, The University of Agriculture, Peshawar, Pakistan.Journal Article19700101Extension Field Staff (EFS) is the group of people who are responsible for managing activities related to agricultural information dissemination and farming community is the recipient or audience of that knowledge by implementing this knowledge on farm. The present study was based on primary data, collected from agricultural EFS using interview schedule in cotton belt of Punjab Province. EFS workers (359) were selected from population of 540 by using Cochran sampling technique. Moreover, Borich Needs Assessment Model was implied to prioritize the training needs of EFS about climate adaptation. Our study found that the majority of the EFS seek trainings in specific areas regarding climate variability. These included skills to use meteorological instrument, ability to comprehend early warning system, serving and mapping of climatic variability areas, management of ICT tools for weather forecasting, disaster management skills, and integrated soil management skills. By acquiring these competencies, EFS can effectively and efficiently work for minimizing the consequences of climate variability on cotton crop. There was significant positive correlation of 0.608 between specialization and the possessed competencies regarding climate adaptation, which showed that specialized extension staff possessed competencies regarding climate adaptation. The findings suggests that the training needs of the extension workers should be assessed regularly and suitable training sessions be arranged for them in the cotton belt.https://jast.modares.ac.ir/article_16862_3550284cdc2575eae68335f00870aaab.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Determinants of Consumption Intention of Fresh Fruit and Vegetable: The Extended Theory of Planned Behavior5055191687510.48311/jast.2026.16875ENAfsanehNikoukarDepartment of Agriculture, Payame Noor University, Tehran, Islamic Republic of Iran.MiladAminizadehDepartment of Agricultural Economics, Faculty of Agriculture, Ferdowsi University of Mashhad, Mashhad, Islamic Republic of Iran.0000-0003-1253-8599Journal Article19700101The purpose of this study was to determine the predictors of Iranian consumers’ intention to consume fresh fruit and vegetable. This study investigated the relationship among attitude, subjective norm, perceived behavioral control, health involvement, subjective health, and Iranian consumption intention by using the Theory of Planned Behavior. The Partial Least Square-Structural Equation Modeling was applied to estimate the model. The results revealed that subjective health (<em>β</em>= 0.463; P< 0.001) as a self-rating of overall health was an important predictor of Iranian consumers’ intention to eat fresh fruit and vegetable. Consumers’ health involvement (<em>β</em>= 0.198; P< 0.001) that shows the importance of health issues for individuals, had significant effect on consumption intention. Other variables such as subjective norms (<em>β</em>= 0.175; P< 0.001), positive attitude towards fresh fruit and vegetable consumption (<em>β</em>= 0.125; P< 0.01), and perceived behavioral control (<em>β</em>= 0.110; P< 0.001) were significant predictors of consumption intention, respectively. The results provide useful and important information about the main determinants of consumption intention for policy-makers to create effective and well-functioning public health policies aimed at increasing the consumption of fresh fruit and vegetable.https://jast.modares.ac.ir/article_16875_92bdee4b02b1dab018f526948437d3d6.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Energy Consumption Patterns, Environmental Sustainability and Human Development Outcomes in Iran5215351686910.48311/jast.2026.16869ENMohammad HassanTarazkarDepartment of Agricultural Economics, School of Agriculture, Shiraz University, Shiraz, Islamic Republic of Iran.NavidKargar DehbidiDepartment of Economic, Social and Extension Research, West Azerbaijan Agricultural and Natural Resources Research and Education Center (AREEO), Urmia, Islamic Republic of Iran.0000-0003-1366-3084EffatGhorbanianDepartment of Agricultural Economics, School of Agriculture, Shiraz University, Shiraz, Islamic Republic of Iran.AzarSheikhzeinoddinDepartment of Agricultural Economics, School of Agriculture, Shiraz University, Shiraz, Islamic Republic of Iran.Journal Article19700101A major goal of this study was to document how renewable and non-renewable energy consumption is related to human development in Iran. For this purpose, all variables were tested for structural breaks using the breakpoint unit root test. Additionally, long-run relationships are examined using the Auto-Regressive Distributed Lag (ARDL) bounds test. The outcomes of the diagnostic tests showed that the panel ARDL model parameters were stable, predictable, and reliable in the long term. Significant positive and negative relationships were found between renewable and non-renewable energy consumption and the Human Development Index (HDI), respectively. Additionally, the elasticity of renewable energy consumption was lower than that of non-renewable energy consumption. Human development in Iran has also been enhanced by CO<sub>2</sub> emissions. Conversely, economic growth and increased trade transparency would lower the HDI in Iran. To improve human development in Iran, energy consumption as well as clean energy production and consumption should be considered.https://jast.modares.ac.ir/article_16869_b1491b673670aeae2dbf8827ba87a758.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Evaluating Competitive Advantages and Market Dynamics in the Global Raisin Industry5375491688310.48311/jast.2026.16883ENMortezaMajidianDepartment of Agricultural Economics, Faculty of Agriculture, College of Agriculture and Natural Resources, University of Tehran, Karaj, Islamic Republic of Iran.0000-0003-0370-5180EsmaeilPishbaharDepartment of Agricultural Economics, Faculty of Agriculture, College of Agriculture and Natural Resources, University of Tehran, Karaj, Islamic Republic of Iran.0000-0001-7826-5437Journal Article19700101Raisins are a key export commodity due to their nutritional value and global demand.

However, the research concerning rural entrepreneurship ecosystem has been largely focused on empirics from developed regions. In this study, in order to explain the drivers of rural entrepreneurship ecosystem in a developing region, the data was collected from 103 rural entrepreneurship practitioners through a survey in northern area of Iran. The data was then analyzed using the exploratory factor analysis method. The research team considered the rural entrepreneurship ecosystem supporters in three pillars: policy-making, institution, and society. According to the results of exploratory factor analysis, each triple supporter pillar of the rural entrepreneurship ecosystem was divided into two components. The components extracted from the policy pillar included "rules and regulations" and "infrastructure." The components extracted from the institutional pillar included "networking and informing" as well as "services and support." In addition, "tendencies and characteristics of the people" and "financial participation" were assumed as the society components. These results were discussed and provided agenda for future practical and professional works.https://jast.modares.ac.ir/article_16870_6a58d9ef674a31d1d5205a2e5429f603.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Practical Assessment of the Effectiveness of Beekeeping Training Courses Using Return on Investment5715881688210.48311/jast.2026.16882ENKhadijehBazrafkanDepartment of Socio-Economic and Agricultural Extension Research, Agricultural Research, Education and Extension Organization (AREEO), Tehran, Islamic Republic of Iran.HasanAlipourDepartment of Socio-Economic and Agricultural Extension Research, Agricultural Research, Education and Extension Organization (AREEO), Tehran, Islamic Republic of Iran.0000-0002-9098-0334Journal Article19700101The effectiveness and Return On Investment (ROI) of agricultural training programs have always been among the most significant challenges for experts and managers in agricultural extension and development.

This experiment was conducted in a factorial arrangement based on a randomized complete block design with three replications in the research farm of the Kurdistan University, during 2021 and 2022. The treatments included fertilizer (control, organic, and chemical) and cropping patterns (sole cropping of borage, sole cropping of peanut, 50%, and 100% additive intercropping). The results indicated that intercropping enhanced the quality traits of borage forage. The fertilization treatments improved the yield and qualitative traits of peanut fodder. Organic fertilizer increased crude protein in borage and peanut fodder by 29 and 20.4%, respectively, compared to the control. Intercropping increased the protein yield of borage by 16.6% compared to sole cropping. The Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), dry matter digestibility, and ash content in borage fodder in the 100% intercropping with organic fertilizer increased by 46, 46, 30, and 58.4%, respectively, compared to sole cropping without fertilizer.

This study proposes a non-invasive and automated approach that combines laser speckle imaging with deep learning to identify early-stage germinated defects in beans. Speckle images were captured under coherent laser illumination (λ= 633 nm) for samples subjected to germination periods of 0, 6, 12, and 24 hours. Two contrast analysis techniques were evaluated: Laser Speckle Spatial Contrast Analysis (LASCA) and the more advanced Laser Speckle Temporal Contrast Analysis (LASTCA), the latter using temporal intensity fluctuations across 120 video frames. From the resulting contrast maps, regions of interest (50×50 pixels) were extracted and used to train a Convolutional Neural Network (CNN) for binary classification. The proposed system achieved high performance, with an accuracy of 92.33% and sensitivity of 98.21%, successfully detecting germinated defects invisible to conventional inspection. By integrating temporal bio-speckle analysis with deep learning, this method offers a scalable solution for intelligent, non-destructive grain inspection—addressing a critical gap in current computer vision systems and contributing to the advancement of Agribusiness 4.0.<br><br><br><br><br>https://jast.modares.ac.ir/article_24094_8c3af53f6554ac306d481a872a47fb83.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Population Abundance of the Red Scale Insect Aonidiella aurantii (Hemiptera: Diaspididae) on Different Cardinal Directions of Guava Trees6997141687110.48311/jast.2026.16871ENMoustafaBakryScale Insects and Mealybugs Research Deppartment, Plant Protection Research Institute, A.R.C, Dokki, 12619 Giza,YaghoubFathipourDepartment of Entomology, Faculty of Agriculture, Tarbiat Modares University, Tehran, Islamic Republic of Iran.0000-0002-7963-5409Journal Article19700101The red scale insect, <em>Aonidiella</em> <em>aurantii</em> (Maskell) (Hemiptera: Diaspididae), is a major pest of guava trees. This study investigated the population abundance, preference, and dispersal patterns of <em>A. aurantii</em> in a guava orchard in the Armant District, Luxor, Egypt, over two consecutive years (2022/2024). Monitoring was conducted biweekly, revealing that <em>A. aurantii</em> infested guava leaves year-round at varying densities. The pest exhibited a strong preference for the upper surface of leaves in the basal layer of the southeastern quadrant, where population density remained consistently high throughout the study period. Using preference and dispersal indices, we evaluated sixteen canopy quadrant-layer-leaf surface combinations. The upper surface of the basal leaves in the southeastern quadrant had the highest quantity ratio, preference index, relative abundance establishment rate, and dispersal index, confirming its suitability for <em>A. aurantii</em> compared to other canopy positions. These findings provide critical insights for optimizing sampling and targeted control strategies, supporting the development of an effective Integrated Pest Management (IPM) program against <em>A. aurantii</em> in guava orchards.<br><br><br><br>https://jast.modares.ac.ir/article_16871_386a1940efd5c4d0c584523e580653b4.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Root Architectural Diversity in Wheat Cultivars and Its Role in Response to Terminal Water Stress7157302409910.48311/jast.2026.24099ENAfshinZamaniDepartment of Plant Production and Genetics, School of Agriculture, Shiraz University, Shiraz, Islamic Republic of Iran.YahyaEmamDepartment of Plant Production and Genetics, School of Agriculture, Shiraz University, Shiraz, Islamic Republic of Iran.ArefNowrouziDepartment of Plant Production and Genetics, School of Agriculture, Shiraz University, Shiraz, Islamic Republic of Iran.Journal Article20250916Root architecture plays a key role in optimizing water uptake and sustaining yield under drought stress. The aim of this study was to investigate the role of vertical root distribution in determining the performance of three irrigated wheat cultivars under Terminal Water Stress (TWS). A field experiment was conducted during the 2021–2022 growing season at Shiraz University, evaluating three bread wheat cultivars: Pishgam, Torabi, and Sirvan. The low-cost "pasta strainer" method was adapted and employed to assess wheat mature root architecture in this context. To assess vertical root distribution, roots protruding through the side perforations of strainers were counted at three defined depth intervals: Shallow (2–8 cm; SRN), middle (8–10 cm; MRN), and deep (10–13 cm; DRN). The results revealed significant differences in root architecture among cultivars. Compared to Sirvan and Torabi, Pishgam exhibited a more uniform root distribution across SRN, MRN, and particularly DRN. A significant interaction between irrigation and cultivar was observed for root weight, root volume, shoot biomass, and Grain Yield (GY). Pishgam appeared to be superior in most of the measured traits. GY showed a positive association with MRN and DRN, which was further supported by principal component analysis aligning GY with root weight, root volume, MRN, and DRN. Despite the advantages and limitations of the pasta strainer method, our results demonstrated that cultivar with deeper rooting type, exhibited better drought performance.https://jast.modares.ac.ir/article_24099_dc7e93f32b3083f13ad7fe95f4966d93.pdfTarbiat Modares UniversityJournal of Agricultural Science and Technology1680-707328320260501Bio-Amelioration of Saline Soil Using Aeluropus littoralis, Arbuscular Mycorrhizal Fungus (AMF) and Salt-Resistant PGPB7317451685910.48311/jast.2026.16859ENMasoumehZareiDepartment of Soil Science, Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Islamic Republic of Iran.ElhamMalekzadehDepartment of Soil Science, Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Islamic Republic of Iran.AlirezaMovahedi NaeiniDepartment of Soil Science, Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Islamic Republic of Iran.Journal Article19700101This study aimed to evaluate the capability of the halophyte <em>A. littoralis</em> in symbiosis with <em>Rhizophagus intraradices</em> and <em>Nocardia halotolerans,</em> an indigenous bacterium of saline soils, on phyto-extraction of Na under saline conditions. Salinity treatments included 0 (S0), 100 mM NaCl (S1), 200 mM NaCl (S2), 100 mM NaCl+50mM K<sub>2</sub>SO<sub>4</sub> (S3), and 200 mM NaCl+50mM K<sub>2</sub>SO<sub>4</sub> (S4) levels. Plant fresh and dry weight and chlorophyll content decreased as salinity increased up to S2 level and increased thereafter. Plant root colonization in the inoculation and co-inoculation of AMF+SR-PGPB (Arbuscular Mycorrhizal Fungi (AMF) and Salt-Resistant Plant Growth-Promoting Bacteria) were similar. Compared to the S0 treatment, root colonization in the AMF group decreased by 23.5, 32.6, 13.5, and 26.7% under S1, S2, S3, and S4 treatments, respectively. In the Bacteria+AMF group, the reduction was smaller, with decreases of 2.8%, 3.4%, and an increase of 6.8 and 1.4% under S1, S2, S3, and S4 treatments, respectively. These results indicate that co-inoculation with PGPB mitigated the negative effects of salinity on root colonization. The root and soil glomalin contents increased as salinity increased. Root glomalin in plants inoculated by AMF+SR-PGPB was more than in a single inoculation of AMF under salt stress. This study highlights the potential application of salt-tolerant bacteria and AMF as effective strategies for enhancing plant growth and productivity in saline environments, contributing to sustainable agricultural practices in affected regions.https://jast.modares.ac.ir/article_16859_9300f7b7b99d92c0acf83ea618010e16.pdf
