In this study, effects of sage (Salvia officinalis L.), oregano (Origanum onites L.), rosemary (Rosmarinus officinalis L.), dill (Anethum graveolens L.), cumin (Cuminum cyminum L.), fennel (Foeniculum vulgare var. dulce L.) and Turkish pickling herb (Echinophora tenuifolia L. subsp. sibthorpiana (Guss.)) essential oils applied to plant leaves at different doses on potato growth, tuber yield and quality were investigated. Essential oils were applied to the upper parts of the plant by spraying at doses of 300, 600, 900 and 1200 ppm three times at 15-day intervals, starting 15 days after the completion of emergence. The number of tubers and tuber yield per plant, marketable and total tuber yield, chlorophyll content, starch content, reducing and total sugar content parameters were examined. The effects of essential oil applications on tuber yield and quality were found to be statistically significant, and this effect varied according to application doses. Compared to the control, essential oil applications increased the marketable tuber yield by approximately 38% (300 ppm rosemary essential oil) and the total tuber yield by up to 28% (600 ppm rosemary essential oil). However, rosemary and oregano oils caused phytotoxicity and reduced tuber yield when applied in high doses. Except for sage and oregano, other essential oils positively affected chlorophyll synthesis. Essential oil applications reduced the accumulation of reducing sugar, which negatively affects tuber quality, and the lowest reducing sugar contents were detected in tubers to which fennel and oregano essential oils were applied. In the study, it was understood that tuber yield in potatoes could be increased significantly with the applications of 300 and 600 ppm rosemary essential oil and 300 ppm cumin essential oil.

Current study intends to find out the carbon footprint of Dokuz Eylül University's Tınaztepe Campus and comprehensively assess its environmental impact in the process. The study provides a detailed analysis of carbon emissions resulting from the campus’s energy consumption, transportation, water usage, and other sources. Based on these analyses, the total CO2 emmission of the campus has been determined, taking into account the carbon sequestration capacity of the university's forested area. Calculations performed using the IPCC Tier 1 Model estimate that Tınaztepe Campus's total annual carbon footprint is 2,458.44 tons of CO2. Additionally, the annual carbon footprint per capita has been calculated as 0.059 tons of carbon footprint. According to the findings, the largest portion of carbon emissions is from natural gas consumption, while the smallest is from water consumption. In light of this data, various strategic recommendations have been developed to reduce the campus’s carbon footprint. These recommendations include measures such as increasing energy efficiency, adopting more sustainable transportation methods, and reducing water consumption. The results of this study provide valuable insights for universities to consider when developing sustainability policies.

Kentin en önemli açık ve yeşil alanı olan parklar, kentsel yeşil alan sisteminin bir parçası olmalarına bağlı olarak yaşanılan kentleri çekici ve yaşanır hale getirir, çevrenin monotonluğunu hafifletir, kentlere imaj kazandırır, yapı kitlelerinin yumuşak bir görünüm kazanmasına olanak sağlarlar. Kentlerin sürdürülebilirliğini sağlayan, kent insanı için kaliteli ve konforlu yaşam alanı oluşturan kent parkları, sahip olduğu peyzaj tasarım özellikleri doğrultusunda hitap ettiği kullanıcıları etkilemektedir. Tasarım kriterlerine uygunluğun hem olumlu hem olumsuz yönleri yalnız kent parkını değil kullanıcısı ve kentin tümünü ilgilendirmektedir. İçerisinde hiçbir rekreasyonel aktivitesi bulunmayan, konforsuz, yeşil bir dokusu olmayan mekânlar kente olumlu anlamda bir şey katmadığı gibi bulunduğu çevrenin insanı için de fiziksel, sosyal ve kültürel anlamda bir etkileşim yaratmadığı için kent insanı psikolojisi üzerinde durağanlık ve huzursuzluğa neden olacaktır. Bu çalışmada Niğde ili Merkez ilçesinde bulunan 5 kent parkının yerinde gözlem, tespit ve mevcut durumlarının analiz edilmesi planlanmıştır. Çalışmanın amacı, Niğde İli sınırları içerisinde kent ölçeğinde hizmet sağlayan bazı parkların peyzaj tasarım kriterlerine uygunluğunun tespit edilmesidir. Bu bağlamda belirlenen peyzaj tasarım kriterlerine göre parkların peyzaj tasarımı açısından uygunlukları tespit edilip, parkların mevcut durumlarının analiz edilmesine yönelik değerlendirmeler yapılması planlanmaktadır. Değerlendirme sonucunda mevcut durumun sorununa yönelik peyzaj tasarım kriterlerine uygun olacak şekilde çözüm önerileri sunulacaktır.

Synthetic fungicides that combat plant pathogenic fungi can enhance crop yields, ensuring stable crop production and market quality. However, the increase in the use of fungicides may cause to development of fungicide-resistant pathogen strains and the accumulation of fungicide residues in the food chain above safe limits. This situation underscores the need for improved fungal disease management through alternatives to synthetic fungicides. These alternatives include plant-derived compounds such as essential oils and extracts. Essential oils are known to be potent antifungal compounds against both human and plant pathogens. Aspergillus niger is a toxin-producing fungal disease agent that causes Aspergillus crown rot in peanuts. In this study, the antifungal activities of nine different essential oils from Foeniculum vulgare, Lippia citriodora, Origanum majorana, Origanum minutiflorum, Origanum onites, Origanum syriacum, Origanum vulgare, Salvia aramiensis and Thymus syriacus plants were evaluated against A. niger under in vitro conditions by using disc diffusion test. Among the nine essential oils tested, the highest antifungal activities were displayed by O. vulgare essential oil (with an inhibition zone diameter of 49.33 mm) which was followed by T. syriacus, O. onites, O. syriacum and O. minutiflorum essential oils (48.67, 47.00, 46.33 and 43.33 mm, respectively). The essential oils of F. vulgare, L. citriodora, and O. majorana showed relatively lower antifungal effects. The essential oil of S. aramiensis did not show antifungal effect against pathogen. The results indicated that plant essential oils could be valuable in promoting research aimed at developing new antifungal agent(s) for fungal disease management. However, further studies are needed to optimize the in vivo application conditions of essential oils against A. niger.

Wheat (Triticum aestivum L.) growth is directly affected by sowing dates. However, the yield of wheat in Afghanistan is significantly lower than the global standard. Several factors including fertilizers, sowing dates, seeds and cultivation methods, contribute to this low yield. The objective of this research was to address this critical issue by comparison of the effects of different sowing dates on wheat yield and its components under Kabul climatic conditions. The same experiment was conducted at two sites in 2020 using a randomized complete block design (RCBD) with three replications and twelve treatments. The varieties used were Darolaman-07 (V1), Mazar- 99 (V2), and Chunta-1 (V3) as factor one, and sowing dates of November 10th (S1), November 18th (S2), November 26th (S3), and December 4th (S4) as factor two. Growth and yield parameters measured and analyzed included plant height, number of leaves plant-1, total number of tillers plant-1, leaf area index (LAI), leaf nitrogen content (N), spike length, number of spikelets spike-1, number of grains spike-1, grain weight spike-1, thousand- grain-weight, days to maturity, number of spikes plant-1, biological yield, grain yield, straw yield, and harvest index. Sowing dates had significant effects on some wheat growth and yield parameters. Sowing on November 10th, 2020, resulted in the highest plant height and leaves number per plant compared to later sowing dates. There was a significant interaction between sowing date and variety at (P˂0.01) in both growth and yield parameters. ANOVA analysis highlighted significant differences among wheat varieties in spike length, grain weight spike-1, thousand grain-weight, and harvest index, with notable variations observed among different varieties. Based on the results, the longest duration to maturity and the highest grain yield were observed on sowing date of November 10, 2020.

Narrow and twin row sowing methods are agronomic applications that aim to increase plant growth and yield by expanding the plant's growing area but, they are highly affected by environmental conditions. The aim of this study is to determine the applicability of different narrow row and twin row sowing methods in clay textured soil in main crop cultivation of corn, which an important grain. The study was carried out Diyarbakır province in the Southeastern Anatolia Region of Türkiye in 2016 and 2017. In the study carried out with two different corn varieties, line abreast narrow row, diagonal narrow row, line abreast twin row, diagonal twin row, single row 1 (70 cm row spacing, 20 cm intra-row spacing) and single row 2 (70 cm row spacing, 12.5 cm intra-row spacing) applications were tried. ADA 351 and Sakarya corn varieties were used in the study. As a result it was determined that line abreast narrow row, diagonal narrow row, line abreast twin row and diagonal twin row applications are not suitable for corn cultivation. The highest grain yield was obtained from single row and 12.5 cm intra-row spacing application.

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.

The faba bean (Vicia faba L.) is a winter crop that can be cultivated as a versatile crop. It’s yield and quality being strongly influenced by environmental and agronomic factors, nutritional content, medicinal properties, and ability to fix nitrogen biologically. Therefore, to maximize advantages of faba bean cultivation, choosing the appropriate varieties, planting times, techniques, plant density, depth of sowing, and ensuring proper crop nutrients and irrigation is essential. For successful faba bean production in subtropical climates, it's important to assess the performance of different varieties under these specific conditions. Planting dates and soil temperature are crucial for germination, growth, and yield. At the same time, the crop's performance is also influenced by sowing methods, plant density, sowing depth, and water and fertilizer management. Integrating faba beans into cropping systems is expected to offer various ecological benefits. This paper reviews the existing literature on the agronomic practices of faba beans.
