Do Geographical Indications Enhance Export Outcomes? An Export Performance Assessment of GI-Certified Turkish Fruits and Vegetables 全文
2025
Mustafa Ergün
This study examines whether Geographical Indication (GI) certification is associated with improved export performance measured by export value, volume, and unit price for five Turkish horticultural products (cherries, pomegranates, grapes, beans, and watermelons) during 2020–2024. The purpose of the study is to investigate whether GI certification contributes to measurable improvements in export competitiveness, particularly in terms of value, quantity, and unit price, and to determine the extent to which these effects vary across different product types and certification durations. Drawing on secondary data from official trade databases, the analysis employs descriptive statistics, trend-based regression, and comparative time-series visualization to assess post-GI dynamics. Results indicate that GI effects are product-specific and sensitive to the duration of certification: cherries, with long-standing GI protection (since 2004), consistently achieve the highest unit prices, suggesting durable premiums; grapes and pomegranates (recently certified) show early signs of price differentiation despite volume variability; beans and watermelons exhibit limited or no improvement in export metrics, implying that GI status alone is insufficient for competitiveness. Overall, GI labeling can enhance trade performance when paired with supportive market strategies (branding, quality assurance, international promotion) and sufficient time to mature. Given the short horizon, lack of firm-level data, and absence of formal counterfactuals, findings are exploratory rather than causal.

The decreasing food resources are the main factors that negatively affect the increasing population and production capacity around the world. In particular, due to global warming and climate change, the required nutrient resources are limited. This triggers the search for alternative resources in animal production. One of the main problems faced by animal production is the inadequacy of feed resources. In recent years, various alternative feed sources have been found to solve this problem. However, it has only been a solution for nutrition. In recent studies, biochar has been found to be both a feed source and capable of preventing global environmental problems. Biochar is generally a solid by-product with added value, formed because of the thermochemical conversion of waste biomass resulting from industrial, forest, plant and animal production. Biochar; while previously used as litter material in animal production, in recent years it has started to be used as an alternative feed source. It has begun to be used as a food source for many animals species, especially ruminants, monogastrics, poultry and aquaculture. The results of many studies indicate that biochar provides significant improvement in yield and performance characteristics such as meat, milk and eggs. It is most striking features include significantly reducing emissions generated during the breeding of different animals species and increasing environmental sustainability. The aim of this study was to provide information about the use of biochar as an alternative feed source in animal nutrition.

Hasna Elalaoui Elabdallaoui | Youssef Mourdi | Abdelaziz ElFazziki | Mohamed Sadgal
This article explores an intelligent and equitable approach to collective and participatory irrigation for small farmers, with an emphasis on the democratization of water use. It examines how this equitable irrigation approach can contribute to the social economy by improving irrigation efficiency and reducing costs for farmers. This work highlights the socio-economic benefits of this approach and highlights its potential to promote democratic water management particularly for small-scale farmers. To do this, we propose a collective irrigation system using a Particle Swarm Optimization (PSO) algorithm, to accurately estimate crop water needs, a method of equitable distribution of water according to needs. Additionally, we propose a novel weighted aggregation technique to establish irrigation priorities among crops, taking into account factors such as crop yield, water scarcity, and economic value.

Population growth has increased demand and diversified use of Irish potato which have increased its demand. The crop has become a major source of food and income for many households across the world. However, despite the high potential of about 30 tonnes per hectare (ha), smallholder farmers in Kenya realize low Irish potato yields ranging from 4-8 tonnes per ha due to limited uptake of agricultural technologies. The low yields calls for a profound understanding of the factors influencing the uptake agricultural technologies. The study analyzed the effects of the adoption of agricultural technologies on Irish potato yield in Ol Kalou Sub County. The study considered chemical fertilizer, certified seeds, fungicides, and farm machinery as the four main agricultural technologies that that affect yield. A descriptive cross-sectional research design was used to obtain data from a study population of 21,942 smallholder Irish potato farmers in Ol Kalou Sub County. A multiple-stage sampling technique was employed to generate a sample size of 385 respondents who provided primary data. Data collected was analyzed using endogenous switching regression model using STATA version 17. The study found that the average treatment effect on treated (ATT) was 10.21 bags per acre. In addition, the Endogenous switching regression model showed that the expected yield for the adopter increased by 51.83%. Out of the four technologies, the use of chemical fertilizers had the highest effect of 37% on yield. The study concluded that the adoption of agricultural technologies increases the yield of Irish potatoes. The study recommends that national and county governments should develop policy regulations such as training and extension services, market access, price support and public-private partnerships encouraging farmers to uptake agricultural technologies. The study also recommends that both levels of government should subsidize agricultural technologies, hence reducing the cost of adoption.

2025
Filiz Arıcak
One of the cornerstones of a developed economy is undoubtedly the agricultural sector. Agriculture is at the center of both human nutrition and economic activities. The use of drones, especially in the process of spraying fields, has the potential to increase the efficiency of agricultural production. Drones can be programmed to scan the field and spray pesticides on these areas. This allows farmers to manage the processes of protecting their crops and removing pests more effectively. Spraying with drones minimizes the negative effects encountered in spraying with tractor-drawn machines. Drones can easily reach places that tractor-drawn machine cannot reach and can spray more precisely. In addition, thanks to drones, the need for labor is also reduced, so that one person can spray a large area in a short time. In this study, the process of spraying with drones was observed in detail by a company with an unmanned aerial vehicle-2 (UAV) license for agricultural spraying. This modern spraying method using drones was meticulously evaluated step by step. In traditional methods, farmers or workers may be directly exposed to pesticides while spraying with tractor-drawn machines, but thanks to drones, this exposure is minimized, which provides a great advantage in terms of occupational health and safety (OHS). In addition, the speed of the work process, less use of water and pesticides, and the need for labor are among the advantages. However, the problem of not being able to connect to GPS, accidents that may occur under the command of the drone, and limitations such as adverse weather conditions can be considered disadvantages of drone spraying. The findings reveal how drone spraying has transformed agriculture.

Gülden Özgünaltay Ertuğrul | İkbal Aygün | Erkan Urkan
This study comprehensively examines the applicability of the 5S methodology as a tool for enhancing efficiency, occupational safety, and sustainability in the agricultural sector. The 5S methodology, predicated on the principles of sorting, organising, cleaning, standardising, and sustaining, aims to create safer and more productive workplaces. The research investigates its effects on both indoor agricultural machinery manufacturing processes and outdoor crop production practices. The analysis reveals notable advantages in manufacturing processes, including reduced waste, enhanced occupational safety, and improved product quality, particularly in production, assembly, and quality control processes. However, the methodology faces limitations in outdoor agricultural practices due to seasonal variations and open-field conditions, which challenge the cleaning, sorting, and organising stages. However, its application in maintenance, repair, and equipment storage processes has been shown to prolong the lifespan of machinery and ensure safer working conditions. The 5S methodology aligns with the United Nations Sustainable Development Goals, serving as a practical approach to enhancing efficiency, workplace safety, and resource management in the agricultural sector. This study underscores the 5S methodology's promise as a sustainable solution for enhancing productivity and safety in agriculture.

Soner Yiğit
This study proposes a reliable and easy understandable statistical solution for the selection of varieties in the balanced and partially balanced lattice experiments, which are widely used in plant breeding studies. For this purpose, the Analysis of Means (ANOM) was adapted to the balanced, simple and triple lattice designs and an R function is developed for it. The adapted ANOM approach was compared with the Tukey, Duncan and Fisher’s LSD tests with respect to the actual type I error rate in all of the balanced, simple and triple lattice designs. In addition to this, the ANOM approach and Tukey test were examined comparatively using a hypothetical example. According to the simulation results, LSD and Duncan could not maintain the actual type I error rate at 5.00% under any conditions. This situation became more dramatic with the increase in the number of groups. While the actual type I error rate for LSD and Duncan tests varied between 54.36%-100.00% and 37.49%-99.96%, respectively, for ANOM and Tukey tests it varied between 4.64%-6.08% and 4.62%-6.45%, respectively. ANOM and Tukey tests were quite successful in terms of maintaining the actual type I error rate. However, since the number of groups in lattice designs was quite high, the given hypothetical example showed that it would be more understandable to use the ANOM method.
