This study analyzes Türkiye’s fresh fruit and vegetable exports over the period 2010–2020, focusing on product-level, spatial, and temporal dynamics. Using disaggregated data from the Turkish Exporters Assembly, the research combines time series analysis, spatial visualization techniques, and a series of fixed effects panel data models estimated separately for each product. By incorporating a year-specific dummy variable for 2020, the models capture the average price dynamics over time and allow for the identification of the COVID-19 pandemic’s distinct impact on each product’s Free on Board (FOB) export value. The findings indicate that high-value-added products have become more diversified, with the Aegean and Mediterranean regions standing out as key contributors to total export value due to their infrastructural capacity and crop diversity. The results further reveal that the pandemic triggered statistically significant price increases for several products including pear, strawberry, apple, date, fig, peach, and grape suggesting a shift in international demand towards health-promoting and durable fresh produce. Overall, the study underscores the need for export strategies that emphasize not only volume expansion but also unit value growth, regional competitiveness, and product-level resilience to global shocks.

Temperature and rainfall are critical variables influencing crop production in tropical regions such as Ile-Ife. Understanding recent trends in these variables is essential for helping farmers adapt to the impacts of climate change. This study analyzed 12 years (2011–2022) of daily air temperature and rainfall data from the automatic weather stations (AWS) at Obafemi Awolowo University (OAU), Ile-Ife, to identify trends and potential evidence of climate change. Summary and inferential statistical methods, including bar and line charts, mean, standard error of the mean, range, and regression analysis, were used for data analysis. Results showed rainfall pattern that has become more erratic with higher interannual variability, delayed onset, increased concentration in fewer months, and frequent extreme events, all of which indicate the intensifying impacts of climate change on local agriculture. The mean annual rainfall and range were 1505 mm and 675 mm to 2829 mm, respectively, with a declining trend (b = -45.62 mm) and a significant R² value of 0.48. Mean air temperature ranged from 25.2°C to 28.2°C with a declining trend over the past decade, and reduction in maximum annual temperature in contrast with earlier reports and global warming projections. Findings suggest that climate change at this location is characterized more by concentrated high rainfall events between June and August rather than a reduction in total annual rainfall or a significant temperature increase.

This study investigated the effects of lactose-free and regular kefir on Drosophila melanogaster lifespan, by applying four doses (5%, 10%, 15%, 20%) to assess their impact on aging through mathematical modeling. We hypothesized that kefir's probiotic content could extend lifespan through its bioactive compounds, with the observed differences potentially attributable to lactose content and dosage. Wild-type flies were divided into groups: a control group fed with a standard diet (SDB), and groups fed regular or lactose-free kefir at varying concentrations. Each group comprised 100 male and 100 female flies, with three replicates, maintained at 25°C and 60% humidity. Daily survival data were collected and analyzed using the Gompertz model to evaluate lifespan and aging rates. Results showed that regular 15% kefir increased average lifespan from 61.2 to 68.2 days for females, and 63.5 to 70.0 days for males, while lactose-free kefir at the same dose extended it to 72.4 and 73.9 days, respectively. Aging rates decreased most significantly at 15% lactose-free kefir, indicating slower aging. However, at 20%, lifespan gains diminished, indicating a complex dose-response relationship that warrants further investigation. These findings suggest kefir's anti-aging potential, with lactose-free kefir showing greater efficacy (18.3% increase in females and 16.4% increase in males), and highlight the importance of dose optimization in aging research.

Extruded foods are shaped, cooked products made by forcing ingredients through a high-temperature, high-pressure extruder. This study optimized extrusion conditions for snacks made from acha-peanut blends enriched with carrot and orange-fleshed sweet potato (OFSP) flours. Using material balancing, four formulations were developed to meet a 19 g/day target: A (100% acha), AP (81.08% acha + 18.92% peanut), APC (64.21% acha + 20.64% peanut + 15.15% carrot), and APO (64.55% acha + 20.74% peanut + 14.71% OFSP). A two-level factorial Central Composite Design was employed to study the influence of moisture (14–22%) and temperature (100–120 °C) on the physical characteristics and acceptability of the snacks. Results indicated that 100% acha (A) snacks had the largest diameters (13.3–14.9 mm) and lowest densities (apparent: 0.41–0.54 g/ml; bulk: 0.13–0.17 g/ml), leading to high porosity (0.68–0.80), expansion ratios (4.43–4.97), and overall acceptability (6.85–8.25). AP snacks exhibited slightly smaller diameters (12.7–13.9 mm), higher densities (apparent: 0.46–0.60 g/ml; bulk: 0.13–0.21 g/ml), moderate expansion ratios (4.23–4.67), and acceptability scores (7.50–8.00). APC snacks had increased densities (apparent: 0.54–0.60 g/ml; bulk: 0.16–0.28 g/ml), smaller diameters (9.5–11.7 mm), lower porosity (0.53–0.71), and reduced expansion ratios (3.17–3.90), with acceptability scores (6.55–8.15). APO snacks yielded the densest snacks (apparent: 0.60–0.71 g/ml; bulk: 0.29–0.41 g/ml) with the smallest diameters (7.9–9.0 mm), lowest expansion ratios (2.63–3.00), and the least acceptability (6.50–8.10). Regression analysis indicated that higher moisture content decreased density and acceptability, while increased temperature enhanced porosity and expansion especially in AP and APO snacks. Optimal extrusion conditions were identified as: A (14.57% moisture, 113.33 °C), AP (19.90%, 120 °C), APC (18.93%, 118.79 °C), and APO (17.72%, 113.94 °C). Further studies are suggested to evaluate the quality and shelf-life stability of the optimized products.

In this study, Standard Precipitation Index (SPI) and Percent of Normal Index (PNI) values were found in order to determine the drought conditions between 2012-2020 in Ankara province. Drought severity interpretations were made according to the index values obtained and these values were evaluated together with some grain yields grown in the region. Separate regression analysis was performed between the different drought index values obtained within the scope of the study and the irrigated and dry agricultural yield values of wheat, barley and triticale. According to the index values calculated between 2012 and 2020 according to the SPI method, drought conditions are generally close to normal in the region. According to the PNI values, it was determined that 2013 had mildly dry conditions and other years had near-normal drought conditions. According to both indices, a drought close to normal was observed during the research period. In the regression analysis made according to wheat, barley and triticale yields, the highest linearity was obtained in barley, and values close to barley were found in triticale. Wheat is the cereal with the lowest linearity. The regression coefficients obtained as 0.4294 for barley, 0.3331 for triticale, and 0.0502 for wheat were found to be 0.0584 for SPI and 0.0013 for PNI. According to the results obtained, it can be said that statistically linearity is in barley and triticale. In average yields, an increase of 47% in wheat, 55% in barley and 34% in triticale was observed with irrigation. In order to ensure sustainable grain cultivation in drought conditions, it is recommended to expand modern irrigation practices in coordination with drought analysis studies and to increase scientific studies on this subject.

The edible mushrooms are valued by people because they possess a large variety of secondary metabolites with diverse beneficial effects on human health. The Agaricales order is one of the largest taxon in fungal systematics represented by a number of edible species in Türkiye. This study aimed to evaluate the antioxidant and antimicrobial activities, as well as the fatty acid composition, of four Agarics (Agaricus bitorquis, Coprinopsis atramentaria, Coprinellus micaceus, and Leucoagaricus leucothites) collected from Nigde Province, Türkiye. The antioxidant capability was determined using DPPH assay and the total phenolic content was measured by Folin-Ciocalteu’s phenol reagent technique. Among the four species, A. bitorquis showed the highest DPPH radical scavenging activity (84.259±1.32%) and total phenolic content (1472.21±10.35µg GAE/mL). Gas chromatography-mass spectrometry (GC-MS) technique was performed for the analysis and characterization of the fatty acid compositions. Linoleic acid was the major fatty acid detected in all four species, with percentages ranging from 23.58% to 42.96%. The antimicrobial activity of the mushroom extracts was assessed using the disc diffusion method, and the ethanol extract of C. atramentaria showed the most significant effect on E. coli with a 29±0.6 mm inhibition zone diameter.

Pea (Pisum sativum L.) is the second most important cool-season food legume in Ethiopia after faba bean, both in terms of production area and annual yield. The study comprises 13 advanced field pea genotypes that were evaluated in a randomized complete block design with four replications across four different environments during two consecutive main cropping seasons (2020–2021). The primary objectives were to identify a field pea genotype with a reliable, high grain yield that could be subsequently released as a new cultivar for farmers in specific areas of Ethiopia.  A combined analysis of field pea grain yield revealed a significant difference (P < 0.01) between genotypes and environments, suggesting that the genetic composition of the genotypes varied and the environments were distinct. The average grain yield ranged from 1614 kg/ha to 2412 kg/ha, with a mean of 2032.69 kg/ha. Genotype G13 had the highest average grain yield (2412 kg/ha) compared to the standard check varieties Bilalo (2190 kg/ha) and Bursa (2100 kg/ha), indicating its potential for developing adaptable varieties suited to specific environments. This outcome may aid breeders in choosing the most appropriate cultivars for particular environments, resulting in higher field pea yields and productivity. Nonetheless, the research also indicates that to create broadly adaptable and climate-resilient varieties, it is crucial to carry out trials in various locations and across multiple years.

Viral diseases are among the most significant challenges in protecting plants of the Cucurbitaceae family, with viruses from the Potyvirus genus, such as zucchini yellow mosaic virus (ZYMV) and watermelon mosaic virus (WMV), causing up to 100% yield losses under favorable conditions.  Despite the importance of these viruses, there have been no previous studies investigating potyvirus diseases in Cucurbitaceae production areas in Çanakkale province. Consequently, the status of these diseases in the region remains unknown. This study aims to address this gap by analyzing the presence of potyviruses in Cucurbitaceae production areas in Çanakkale. In the 2021 production year, a total of 137 samples exhibiting virus and virus-like symptoms were collected from various Cucurbitaceae production sites in Çanakkale province and its districts. The samples were tested using RT-PCR with primer pairs specific to WMV and ZYMV. From the infected samples, seven isolates were selected for further analysis, and the coat protein (CP) genes were amplified and sequenced. The results revealed that WMV was detected as a single infection in 78 samples, ZYMV in one sample, and mixed infections of ZYMV+WMV were found in 39 samples, indicating that WMV is notably prevalent in Çanakkale. Bioinformatics analyses demonstrated that the Turkish WMV and ZYMV isolates share more than 90% similarity with other isolates in both the local samples and the GenBank database. Phylogenetic analysis further revealed that Turkish WMV and ZYMV isolates are closely related to each other. This is the first study to reveal the presence and phylogenetic relationships of ZYMV and WMV in cucurbitaceous plants in Çanakkale province of Türkiye.
