Hatice Bozoğlu | Zeynep Aybey
Germination is the first stage of a plant’s life. The seeds of grain legumes are used both as food and as seedlings. The vitality of the seeds is crucial for both uses. This study was conducted to determine the effect of storing seeds of the Lara variety of Faba bean (Vicia faba L.), harvested in 2023, in different periods (4, 6, 8, 10 and 12 months) and different storage medium (paper bag, plastic bag, glass jar and plastic bottle) on their biological value. The experiment was set up in a completely randomized design with three replications. Germination was done in 2 different materials (sand and paper) in room conditions. Germination speed, germination power, length of plumula and radicle, dry matter of them, seedling vigour index, allometric coefficient, germination energy were observed. On the 4th day, which is considered in determining the germination rate for faba beans, no germination value was determined in any process. Germination power values varied between 72.7% and 97.3%. The highest germination value was obtained from seeds stored for 8 and 10 months. The highest value was recorded in plumula and root length values in 12 and 8-month-old stored seeds, respectively. It was determined that storage medium did not have a single effect on the observed measurements for these experiments. However, statistical differences between storage period and storage material interactions were found to be significant. The statistical differences between storage period and storage material interactions were found to be significant. As a result, it was concluded that the germination rate of the faba bean was early on the 4th day, the counting day, and this value should be studied. It has been concluded that the loss of germination power is very low in about 1 year of storage of faba bean, which have strong germination ability.

Tissue monitoring generally includes the stages of fixation, dehydration, clearing, hardening (infiltration), paraffin blocking/paraffin(emmeding), sectioning, water removal, routine staining, and mounting. Fixation is the basic and first step in the microscopic examination of tissues. The histotechnical process, which includes components such as detection, tissue tracking and staining, basically aims to capture and visualize the state of the relationships between tissue parts inside and outside the cell and various cells at a certain time as close as possible to the living state. Maintaining the natural structure of the tissue is important for the follow-up phase. The main feature of a good fixative should protect the sample and make the macromolecules insoluble without changing the chemistry of the sample studied and allowing it to be examined as closely as possible to its living state. In histological tissue analysis including light microscope and electron microscope techniques, an appropriate fixation method is selected for each study. Detection solutions are classified in terms of content. The most commonly used fixative in light microscopic follow-up procedures is 10% formaldehyde. For the electron microscope, the gluteraldehyde-osmium tetraoxide binary is widely used for fixation purposes. Gluteraldehyde acts more slowly and is more expensive than formaldehyde. Formalin is obtained by dissolving formaldehyde in water. In addition, the fixed samples can be stored in the solution for months. With a successful fixation process, the structural properties of the tissue are preserved and thus it is possible to examine the tissue as closely as possible. Thus, better quality sections are obtained from the tissue samples taken. For this reason, it will be more efficient to interpret well-fixed samples by photographing them. In this review, which was created by using various sources, the elements to be considered for an ideal fixation were determined and it was aimed to provide an overview of successful fixation for light microscope and electron microscope.

The global population is increasing at a rapid pace, posing significant challenges to sustainable development and food security. This review paper examines the advantages and challenges of organic farming as a potential solution to address the pressing issues in modern agriculture and food production. Organic farming offers a range of benefits, including improved soil fertility, higher profitability, reduced external input usage, land reclamation, improved market access, and enhanced farmer capacity and self-reliance. Organic farming practices prioritize environmental sustainability by reducing chemical usage and reliance on biological methods of pest control, as well as enhancing biodiversity, which strengthens ecological balance and resilience against pests and diseases. However, organic farming also faces challenges that need to be addressed for its widespread adoption. These challenges include uncertainty surrounding legislative environments, psychological and sociological costs of conversion, financial risks during the transition period, securing marketing channels for organic produce, and diminishing profit margins. Efforts should be made to provide farmers with the necessary support, including technical assistance, subsidies, and access to markets, to overcome these challenges. Despite the challenges, the potential of organic farming in promoting sustainable agriculture and ensuring a secure food system cannot be overlooked. It offers a natural and environmentally friendly approach to food production, prioritizing the health of both humans and the ecosystem.

A survey was conducted in three selected kebeles of Kombolcha Regiopolitan City in South Wollo Zone. The selected kebeles were in proximity to brewery factory, Ethiopia. A semi-structured questionnaire was used to collect perception data from purposively selected three kebeles and a total of 57 randomly selected dairy farmers. Data collected were analyzed with a statistical package for social sciences (Version 20) and Microsoft Excel (2010). Smallholder dairy farmers had average herd size of 10.7 and 0.08 hectare total dairy farm per household. Average daily milk yield and lactation length of dairy cows was 10.8 liter/day and 9.5 months, respectively. The majority of farmers (59.6%) reared dairy cows with 50-75% exotic blood. The most smallholder dairy farmers satisfied their feed demand from the market and had a trend of providing both dense and poor quality affordable feed ingredients. Smallholder dairy farmers gave priority to feed different kind of cattle in the order of lactating cows, calve, pregnant, heifers and dry cows and used (100%) wet brewery spent grain as a source of dairy feed. Though, there was a brewery by-product supply deficit for half of year. The majority smallholder dairy farmers delivered brewery by-product directly from the brewery factories and followed by wholesalers and retailers. The majority of smallholder dairy farmers (96.4%) stated that the brewery spent grain was fed and stored freshly using different conservation techniques, and the remaining stored in ensiled (1.8%) and dried (1.8%) forms. Smallholder dairy farmers had no brewery spent grain ensiling practice and feeding brewery yeast to dairy animals. Smallholder dairy farmers indicated that high price due to abnormal market chain and shortage of brewery spent grain supply were the major challenges to sustain dairy industry in the study area, and the majority (40.6%) claimed to get swift solutions at high cost and less accessible brewery by-product.

Savaş Kuşcu | Kıvılcım Çaktü Güler
Buğday özellikle insanların beslenmesinde büyük rol üstlenmiştir. Yetiştirilmesi son derece zahmetsiz olsada yapılan araştırmalar, iklim değişikliğinden buğdayında olumsuz etkileneceğini ortaya koymuştur. Anadolu’da buğday ekili alanlarda verim ve kaliteyi arttırmak için gübreleme yapılmaktadır. Gübreleme yapılırken uygulanan miktara, uygulama zamanına ve gübre türüne dikkat edilmesi gerekir. Kontrolsüz yapılan gübreleme toprağa ve çevreye zarar vermektedir. Toprağı verimsiz hale getirirken, atmosferede sera gazı salınımına neden olacaktır. Bu durum ise buğday üretiminde ki karbon ayak izinin artmasına neden olacaktır. Yaptığımız bu çalışma da buğday üretimi yapılırken çiftçiler tarafından kullanılan gübrelerin, kullanım miktarına bağlı olarak ürettiği karbon ayak izini hesapladık.

Ayşe Semra Aksoy | Mustafa Yaman | Muhammet Arıcı
Hardaliye, grape-based fermented beverage, rich in antioxidant phenolic compounds. Bioaccessibility and antioxidant capacity of bioactive compounds in hardaliye, produced using varying amounts of mustard seeds (1%, 1.5%, and 2%) with Merlot and Papazkarası grape varieties, were evaluated under in vitro gastrointestinal digestion conditions. After digestion, Merlot and Papazkarası samples with 2% addition of mustard seed showed significantly higher total phenolic compounds (TPC) (358.48±14.73 and 89.01±2.42 mg GAE/L, respectively) compared to other samples (P<0.05). 2% mustard seed added Merlot samples resulted in the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC) values (19.06±3.91 and 9.96±1.83 mmol TEAC/L, respectively) which differed significantly from other samples (P<0.05). The Merlot sample with 2% addition of mustard seed showed significantly higher TPC, total flavonoid compounds (TFC), DPPH, and CUPRAC bioaccessibility values compared to other Merlot samples (P<0.05). For Papazkarası samples with 2% mustard seed addition, significant differences were observed only in terms of TPC and TFC bioaccessibility values (15.87±2.30% and 15.27±1.29%, respectively) compared to samples with 1% and 1.5% mustard seed addition (P<0.05). The study demonstrated that the bioaccessibility of bioactive compounds in hardaliye can vary depending on the grape variety and to some extent, the use of mustard seed. This suggests that the food matrix and interaction with other food matrices in the environment can affect the stability and bioavailability of bioactive compounds during simulated digestion.
