Banana (Musa spp. ‘Grand Naine’) is a climacteric fruit prone to rapid postharvest deterioration, necessitating effective storage interventions. This study investigated the influence of perforated low-density polyethylene (LDPE) and high-density polyethylene (HDPE) packaging on the ripening physiology and quality attributes of bananas over ten days. A Completely Randomized Design (CRD) was used with five treatments including control, LDPE (24 and 48 holes) and HDPE (24 and 48 holes), and four replication per treatment. Fruits were exposed to ethylene (24 hours at 14–20°C, 85–90% RH) and subsequently monitored for ten days at ambient temperature. Quality attributes such as peel color, physiological loss in weight (PLW), firmness, pulp-to-peel ratio, total soluble solids (TSS), titratable acidity (TA), TSS/TA ratio, and pH were assessed. Data were analyzed using analysis of variance (ANOVA) and mean comparisons performed with Least Significant Difference (LSD) tests at a 5% significance level. LDPE with 24 perforations minimized PLW (4.56%) and delayed ripening, while HDPE 24 holes best retained firmness (0.89 kg/cm2). Although TSS and TA trends were similar across treatments, LDPE and HDPE maintained higher pH values, indicating moderated acid metabolism. The TSS/TA ratio increased over time in all treatments, consistent with progressive ripening. LDPE 24 perforations offered the most balanced microenvironment, optimizing water retention and gas exchange. These findings support its application for enhancing banana shelf life and quality in subtropical storage conditions.

Bu çalışma, yumurtacı tavukların beslenmesinde rasyona kurutulmuş dar yapraklı sinir otu (Plantago lanceolata) ilavesinin performans, sarı pigmentasyonu ve diğer yumurta kalite özellikleri üzerine etkilerinin belirlenmesi amacıyla yürütülmüştür. Çalışmada 56 haftalık yaşta toplam 150 adet Lohmann Sandy genotipli yumurtacı tavuk kullanılmış, kontrol rasyonu (sinir otu ilavesiz) ve kontrol rasyonuna iki farklı dozda (1. doz; 0,5 kg/ton yem, 2. doz; 1 kg/ton yem) sinir otu ilave edilmiş deneme rasyonları olmak üzere üç deneme grubu oluşturulmuştur. Çalışma sonucunda, deneme grupları arasında yumurta verimi ve yem tüketiminin benzer olduğu gözlenmiştir (P>0,05). Diğer yandan, yumurta ağırlığının 1.doz grubunda 61.8 g ortalama değeriyle en yüksek, kontrol grubunda ise 58,6 g ile en düşük değerde olduğu gözlenmiştir (P<0,05). Yemden yararlanma oranı ise kontrol, 1.doz ve 2.doz gruplarında sırasıyla 2,06, 1,94 ve 2,02 olarak tespit edilmiştir (P<0,05). Kurutulmuş dar yapraklı sinir otu ilavesiyle yumurta sarı oranının kontrol grubuna göre artış gösterdiği, sarı renginin ise koyulaştığı saptanmıştır (P<0,05). Yumurta sarı rengi kontrol, 1. doz ve 2. doz deneme gruplarında sırasıyla 9,2, 12,6 ve 12,4 olarak gözlenmiştir. Sonuç olarak, yumurtacı tavukların beslenmesinde rasyona ilave edilen 0,5 kg/ton yem seviyesinde kurutulmuş dar yapraklı sinir otu yumurta ağırlığı, yemden yararlanma oranı ve sarı rengi üzerine olumlu etkileri olduğu için, özellikle sarı pigmentasyonu için doğal bir kaynak olarak önerilebilir.

This study first analyses the use of digital technologies in agriculture from two different perspectives. Then, correlation analyses using these data aim to show which countries focus on which of the two perspectives are ahead in agricultural exports. In the study, publications containing the word ‘agriculture’ in the title, abstract, or keywords section of the Scopus database and the keywords ‘digital technology’ and ‘production’ in the all-fields section were selected and recorded as publications in which digital technologies in agricultural production were investigated. Then, in the Scopus database, publications containing the word ‘agriculture’ in the title, abstract or keywords section and the words ‘digital technology’ and ‘marketing’ in the all-fields section were kept in a separate category and recorded as publications in which digital technologies in marketing of agricultural products were investigated. These two data sets were subjected to correlation analysis with export data obtained from OECD databases, and interactions on the axes of agriculture, digital technologies, production, and marketing were revealed. After selecting the OECD member countries with export data from all the data obtained, the number of academic publications of these countries with the specified conditions is given in separate tables. The correlation analysis on OECD member countries revealed a statistically significant and strong positive relationship between the average agricultural export volumes for 2020-2024 and the number of scientific publications containing the terms agriculture, digital technologies, and production indexed in the Scopus database. The Pearson correlation coefficient was calculated as r = 0.813, and the significance level was p = 0.004. When a similar correlation analysis was conducted with publications containing agriculture, digital technologies, and marketing terms, the Pearson correlation coefficient was r = 0.958 with a significance level of p < 0.001. This finding indicates that countries that produce higher levels of academic output in agriculture (publications containing both production and marketing terms) tend to have higher export performance in the agricultural sector. The results suggest that there may be a significant relationship between academic productivity and economic output in international agricultural trade.

Türkiye 2015-2023 yılları arasında dünya arılı kovan sayısında üçüncü, bal üretiminde ise ikinci sırada yer almıştır. Ancak bal üretim miktarı ve kovan sayısı her geçen yıl artmasına rağmen verimin genel olarak düştüğü görülmektedir. Bu çalışma, arıcılık sektörünün temel ürünlerinden biri olan bal üretiminin verimliliğini analiz etmek amacıyla gerçekleştirilmiştir. Veri olarak dünya ve Türkiye’ye ait 33 yıllık istatistikler kullanılmıştır. Ayrıca, Malatya’da, sektörün verimliliğini etkileyebilecek olası faktörleri incelemek amacıyla bir anket çalışması yapılmıştır. Türkiye ve dünya verimlilik düzeyleri karşılaştırılırken, iller arasındaki verim farklılıkları da incelenmiştir. Toplanan veriler tanımlayıcı istatistiklerle değerlendirilmiş; verimlilik farklılıklarını test etmek amacıyla t-testi, ANOVA, Mann-Whitney U testi ve Pearson korelasyon analizleri uygulanmıştır. Sonuçta koloni sayısı ve toplam bal üretiminde Türkiye’nin büyüme oranlarının dünyadan daha yüksek olduğu görülmüştür. Ancak Türkiye’nin kovan başına bal verimi, incelenen dönem boyunca dünya ortalamasının altında kalmıştır. Bu verim düşüklüğü özellikle son yıllarda daha da belirgin hâle gelmiştir. Türkiye’nin bal veriminin bölgesel farklılıklar içerdiği de görülmüştür. Bu durum, sadece üretim hacmine odaklanmanın yeterli olmadığını; verimliliği artıracak stratejilerin geliştirilmesinin gerekli olduğunu ortaya koymaktadır. Bu bağlamda, yüksek verim sağlayan bölgelerdeki iyi uygulama örneklerinin yaygınlaştırılması ve sektöre verilecek desteklerin artırılması önerilebilir.

This study investigates the spatial and temporal variation of thallium (Tl) accumulation in different tissues (outer bark, inner bark, and wood) of Robinia pseudoacacia growing in the city center of Düzce, Türkiye, a region known for severe air pollution. Sampling was performed by sectioning the main trunk at approximately 50 cm above ground level, and Tl concentrations were analyzed using inductively coupled plasma optical emission spectroscopy (ICP-OES). Variance analysis revealed significant differences in Tl concentrations depending on organ type and directional exposure (p <0.001). The highest concentrations were generally detected in the northern orientation, with the outer bark showing particularly elevated accumulation. Temporal evaluations across twelve time periods from 1963 to 2022 indicated a decreasing trend in Tl levels after 2008, suggesting improved environmental conditions in recent years. The results highlight the ability of Robinia pseudoacacia to reflect both spatial and historical patterns of Tl contamination, supporting its use as a medium-sensitivity biomonitor. Additionally, the wood tissue showed a potential to represent long-term cumulative Tl exposure. Overall, these findings suggest that Robinia pseudoacacia could be an effective candidate for phytoremediation and biomonitoring strategies in urban and industrial areas with thallium contamination.

Our study is on the protective effect of lavender oil on oxidative stress caused by copper oxide nanoparticles (CuO NPs). For this purpose, 0.5 mg/kg body weight L. angustifolia, 5.0 mg/kg body weight CuO NPs and their mixtures (0.5 mg/kg body weight L. angustifolia +5 mg/kg body weight CuO NPs) were administered to mice by gavage method for 14 days. At the end of the time, antioxidant activities such as biochemical parameters (ALT, AST, T. Prot, Cholesterol) in mouse blood tissue and their combined effects on copper accumulation in kidney and liver tissues were investigated in male Swiss albino mice. The study results showed that copper accumulation in liver and kidney tissue increased significantly. While ALT and AST values in blood tissue increased compared to control, significant decreases were observed in T. Protein and cholesterol levels. These results showed us that lavender oil was significantly effective in homeostatic effects against any toxicity in mouse blood tissue.

In this research, the effects of different IBA (indole butyric acid) doses on the rooting of ‘Nero’ and ‘Viking’ aronia cultivars were investigated. Wood cuttings of these cultivars were used in the study. After the cuttings were disinfected, they were immersed in 1500, 2000 and 2500 ppm IBA solutions and planted in perlite medium with three replications. The cuttings were kept in a rooting system heated from below for sixty days; callus rate (%), rooting rate (%), number of roots (number), root thickness (mm), root length (cm) were evaluated. In the study, the best callus formation rate in ‘Viking’ cultivar was 55.81% at 2000 ppm, the rooting rate was in the ‘Viking’ cultivar at 2500 ppm (73.11%), the best average root number was in the ‘Viking’ cultivar at 2500 ppm IBA application (1.93 units/stem), the best average root thickness was found in the ‘Viking’ at 2500 ppm (0.23 mm) and the best average root length was found in the ‘Viking’ at 2500 ppm (0.77 cm).

The grapevine is one of the most cultivated, healthy, delicious and refreshing fruit species in the world. The fact that grapes have many different usage methods increases the interest of producers in grapes. In addition, the large berry and showy grapes grown especially for table use also increase the interest of consumers. In our study, different cluster thinning applications were applied to the Samancı Çekirdeksizi grape variety. Thinning the clusters, unlike classical applications, aimed to shorten the cluster sizes by cutting 1/3 and 2/3 of the clusters and improving the berry characteristics. In this context, 1/3 and 2/3 of the tips and shoulders of the clusters were cut. As a result of different cluster thinning applications, cluster, berry and phenolic properties were examined. As a result of 1/3, SR (Shoulder removal) and 1/3 CTR (Cluster Tip Removal) applications, increases were determined in cluster weights. All applications caused increases in berry characteristics, SSC (Soluble Solids Content), maturity index, pH, berry detachment force, skin rupture force, phenolic content and antioxidant activity, while decreases were observed in TA (Titratable Acidity) values. It was concluded that 1/3 SR and 1/3 CTR applications can be applied for both yield and quality increase. In addition, it was seen that the berry size increase, which is an important parameter for table grape varieties, can be achieved by cutting a part of the cluster. In future studies to be conducted with table grape varieties, the idea that it would be more appropriate to cut a part of the cluster instead of cutting all the clusters came to the fore.

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici, has emerged globally as a serious pathogen in wheat-producing regions. Historical evidence suggests that stripe rust prevalence in wheat existed before people began growing wheat as a staple crop. The disease is characterized by yellow-orange pustule stripes on leaves and other above-ground plant parts. Its high mutation ability and remarkable adaptation capacity cause significant losses in the host's biomass and overall grain yield. The disease can be effectively managed through multifaceted approaches, including the selection of resistant varieties, eradication of alternate hosts, optimal use of nitrogen, irrigation scheduling, and the deployment of various biocontrol agents such as Bacillus subtilis, Streptomyces tauricus, and Pseudomonas putida. The application of the fungicides Picoxystrobin, Fluoxastrobin, Pyraclostrobin, Propiconazole, Tebuconazole, Prothioconazole, and Metconazole + Pyraclostrobin has also proven effective in controlling stripe rust. Furthermore, the study aims to explore the application of artificial intelligence, machine learning, and disease forecasting models in addressing prediction and management challenges.
