Plantation forestry primarily aims to enhance the production of high-quality timber. This research focuses on evaluating the effect of various climatic factors (such as relative humidity, annual precipitation, average, minimum and maximum temperatures) on the growth parameters (including tree height, breast height diameter and base diameter) of Taurus cedar (Cedrus libani A. Rich.) and Anatolian black pine (Pinus nigra Arn. subsp. pallasiana (L.) Holmboe). This study was conducted in two adjacent plantations established in 1995, with data collected over a three-year period (2022-2024). To assess growth patterns, 30 trees from each plantation were randomly selected and monitored. Climatic data were sourced from Türkiye’s general directorate of meteorology and climatology. Analysis of variance (ANOVA) revealed that growth and climate parameters were statistically similar (p>0.05) for both species, except for tree height, which showed significant differences in Taurus cedar. The Spearman rank correlation analysis identified a strong and statistically significant relationship (p<0.05) between temperature variables (minimum, maximum, and average) and the growth traits of both tree species. On the other hand, relative humidity and annual precipitation showed no significant correlations (p>0.05). The findings underscore the critical role of temperature in influencing tree growth within plantation forestry, offering valuable insights for sustainable forest management practices.

Seralar, üretim sezonunda birden fazla ürün elde edilmesi ve üretim sürecinin kontrol altında gerçekleştirilerek verim kayıplarının azaltılması açısından gıda arzına önemli katkı sağlayan tarım sistemleridir. Seralarda birim alandan daha yüksek verim almak için özellikleri ve yapıları itibariyle amaca uygun planlanmalıdır. Tarım işletmelerinde seraların planlanmasında en önemli ölçüt yatırım maliyetidir. Bu doğrultuda çalışma kapsamında tiplerine ve teknolojik özelliklerine göre seraların yatırım analizleri, üretilen ürünlerin verimlilikleri ve işletmelerin karlılıkları karşılaştırılmıştır. Çalışmada, Mersin ilinde sebze üretimi yapan 99 adet plastik, 86 adet cam ve 5 adet topraksız sera işletmelerinde anket yapılmıştır. Anket yoluyla elde edilen verilerde; net kar domates üretilen plastik sera işletmelerinde 9.814,15 TL/da, topraksız sera işletmelerinde 109.532,91 TL/da, biber üretilen plastik sera işletmelerinde 5.522,14 TL/da, hıyar üretilen cam sera işletmelerinde 10.460,53 TL/ da belirlenmiştir. Sera tiplerine göre 3,93 yıl ile topraksız sera işletmelerinde yatırımın geri ödeme süresinin daha kısa olduğu ve 6,68 yıl ile plastik serada domates yetiştiriciliğinin takip ettiği tespit edilmiştir. Dolayısıyla net bugünkü değer domates yetiştiriciliği yapılan plastik ve topraksız seralarda pozitif olup bu yatırımların kârlı olduğunu göstermektedir. Benzer şekilde fayda masraf oranı topraksız domates seralarında 2,05 ve plastik domates seralarında 1,13 hesaplanmıştır. Bu nedenle söz konusu iki sera tipinde ve ürünlerinde projenin geliri yatırımından daha fazla olduğu için karlılık yüksektir.

Population growth and the rise in the level of welfare across the world cause an increase in the demand for water, energy and food, while water supply in sufficient quantity and quality is gradually decreasing in parallel. In addition, events such as droughts and floods caused by climate change have negative impacts on ecosystems. In line with the increasing water demand, it is becoming increasingly important to develop sustainable development of water resources, to provide water in the required quantity and quality at the desired place and time, to develop solutions for the effective management of inter-sectoral allocation and to control losses and leakages. Worldwide, the distribution of groundwater and surface water resources by sectors varies between continents over the years and depending on the development of the sectors. When the water consumption rates of domestic (drinking and using), industrial and agricultural sectors, which are the largest users of water resources, are analysed, it is seen that agricultural use is 69%, industrial use is 19% and domestic use is 12% on a global scale. In Turkey, approximately 75% of total water resources are used for agricultural irrigation, while this rate is 33% in Europe. However, the rate of agricultural water use in Southern European countries can reach up to 75%. As is evident, the agricultural sector accounts for the most intensive use of water resources. Agriculture has the most important share in the sustainability of water resources due to its high utilization rate. For this reason, agricultural water use constitutes the main point of ensuring the sustainability of water resources and the most effective use of existing resources. In this study, the basic elements of sustainable urban water management are discussed and a framework for assessing the current water use of Izmir province with a water footprint approach is presented as an example. In addition, a flow chart has been prepared as a basis for the creation of a water footprint map. Such assessments will provide important contributions in terms of ensuring ecosystem sustainability, increasing water efficiency in cities and reducing risks associated with water resources, including food security, and supporting sustainable development.

Agricultural lands are known not only as agricultural production areas but also as areas with high income expectations as an investment tool. In Turkey, recent fluctuations in economic indicators such as the euro, dollar, and gold, along with increasing investment demand, have caused agricultural land prices to rise uncontrollably. Controlling land price increases is important for preventing the misuse of agricultural lands. The sustainable management of agricultural lands and price stability are closely related to the United Nations Sustainable Development Goals (SDGs), particularly SDG 11 and 15, “Sustainable Cities and Communities” and “Life on Land.” In this context, accurately predicting prices is important for minimizing price fluctuations in agricultural lands for investors and landowners and supporting sustainable development. In general, the Multiple Linear Regression (MLR) model is considered one of the effective traditional methods for predicting real estate prices. However, depending on the data, more reliable results can be obtained than with powerful deep learning models such as the Extreme Gradient Boosting (XGBoost) algorithm, which exhibits superior prediction performance. This study aims to compare the MLR and XGBoost algorithms to predict agricultural land prices in villages located in the central district of Çanakkale and to examine daily fluctuations in economic indicators such as the dollar, gold, and euro. The results showed that XGBoost (R2 = 0.66) has an advantage in terms of coefficient of determination values compared to MLR (R2 = 0.01). Accurate price prediction for agricultural lands will help control fluctuations in land prices. Additionally, it will support farmers and investors in making informed decisions for a sustainable agricultural economy.

Bread is among the most commonly consumed foods in daily diets around the world. It is known that breads produced with sourdough or different cereal flours have positive effects on health. Consumer demand for these types of bread is steadily growing. One key factor influencing bread consumption is their sensory qualities. The aim of our study was to assess the sensory properties of sourdough breads made with various cereal flours and a buckwheat (pseudocereal) substitute. For this purpose, six types of sourdough breads were produced with durum (yellow) wheat, wheat, rye, einkorn, wheat germ flours and buckwheat flour as a grain substitute, and these bread varieties were scored between 1-5 by 9 trained panelists according to loaf and crust appearance, crust thickness, crust color, crust odor, crumb appearance, crumb porosity, crumb color, crumb elasticity, chewability, odor, taste, and general appreciation features. As a result of the evaluation, in terms of general appreciation, the average scores of the bread varieties, from the most to the least appreciated, were determined as buckwheat (Fagopyrum esculentum) bread (4.017), durum wheat (Triticum durum) bread (3.811), wheat (Triticum aestivum) bread (3.685), einkorn (Triticum monococcum) bread (3.102), wheat germ bread (3.076) and rye (Secale cereale) bread (3.008). Additionally, when the average total scores were reviewed at the end of the evaluation, it was found that the breads were rated at least 2.5 points (medium), which is above average. Therefore, it was concluded that breads produced with sourdough by substituting buckwheat, durum wheat, einkorn, wheat germ and rye flours could serve as a good alternative to sourdough wheat bread for healthy nutrition by gaining consumer approval.

The agriculture sector is actively looking for the most effective ways to manage water resources. Proper water management is crucial for increasing agricultural productivity and optimizing the region’s water usage efficiency. The purpose of this study was for estimating the irrigation water requirement, reference and crop evapotranspiration and irrigation schedule for cotton in Çukurova region over a 31-year period (1990-2020) using the CROPWAT model. To ensure appropriate water utilization and planning, information regarding the climate data was obtained from the Adana station of Turkish State Meteorology Service. The soil and crop data were sourced from Turkey’s directorate of agricultural research and policies. The dates, amounts, effective rainfall, net irrigation requirement (NIR), and yield decrease for rainfed and different irrigated conditions were all calculated using the CROPWAT 8.0 model. The findings indicated that the average reference evapotranspiration (ETo), crop evapotranspiration (ETc) for cotton and effective rainfall were 918.9 mm, 809.5 mm, and 149.4 mm respectively. It was also estimated that the dates of irrigation after planting (DAP) were 72 days, 101 days, 131 days and 170 days. The total quantity of water utilized for irrigation throughout the growing season at critical depletion and user defined were 700 mm and 545 mm respectively, thus 155 mm of water was saved (22%). Data of maximum crop yield obtained at critical depletion by CROPWAT was associated with data from Turkish Statistical Institute (TUIK) (2014-2020) and TUIK data is compared with CROPWAT data which was estimated under rainfed condition. According to the result 51% of yield reduction was simulated when irrigation was not applied.

The most complex microhabitat is the rhizosphere, which is composed of a varied alliance of archaea, fungi, bacteria, and eukaryotes as well as an interconnected network of plant roots and soil. Crop yield and growth are directly affected by rhizosphere conditions. Plant development and yield were enhanced under nutrient-rich rhizosphere conditions. Most soils that require nurturing before or at the time of next harvest are drained by extensive agriculture. Fertilizers are the primary source of nutrients for crop. However, their extensive and unchecked use seriously threatens ecosystem stability and agricultural sustainability. These toxic substances accumulate in the soil, leak into water, and are discharged into the atmosphere, where they stay for decades and impart a vital risk to the ecosystem as a whole. The rhizosphere of plant growth-promoting rhizobacteria (PGPR) transforms a variety of vital nutrients such as nitrogen, phosphorus, zinc, and others that are unavailable to plants into forms that they can use. In order to interact with the valuable or pathogenic counterparts in the rhizosphere, PGPR produces a variety of hormones such as auxin, cytokinin, gibberellin, antimicrobial agents, secondary compounds, cell lytic enzymes, chitinases, proteases, hydrolases, stress- releasing materials 1-Aminocyclopropane-1-carboxylate deaminase, chelating siderophores, and certain signaling substances such as N-acyl homoserine lactone. PGPR can be used for rhizosphere engineering, which has several uses beyond crop fertilization, development of plant growth, sustainability, and environment friendly agriculture. There is an increasing concern regarding stress-resilient plant growth promoting. microorganisms (PGPM). This review paper covers the three elements of rhizosphere engineering with a particular emphasis on PGPM and how it might promote the appropriate use of rhizosphere engineering particularly in hosts, as an important aspect of environmentally conscious farming.

The current study aimed to evaluate the effect of extraction solvents on the anti-bacterial and anti-fungal efficacy of the stem and roots of Ajuga integrifolia Buch. Ham. ex D. Extracts were prepared in different solvents and tested against fungi and bacteria species including, Agrobacterium tumefaciens, Xanthomonos oryzae, Citrobacter freundi, Alternaria alternata, A. solani and Aspergillus niger. Antibacterial efficacy of the Ajuga integrifolia was carried out by disc diffusion susceptibility method and antifungal efficacy by well diffusion susceptibility method. Methanol stem extract revealed efficacy against C. freundi by producing a 63% zone of inhibition at 3000µg/disc while methanol roots extract produced 77% ZI against A. tumifaciens. Methanol root and stem extracts produced an equal zone of inhibition (97%) at 1000 µg/ml concentration against A. alternata and A. solani. The results of the study clearly stated that the polarity of the solvents used in the extraction procedure affects the bioactivities of the extracts.
