Çeltik, dünya nüfusunun yarısından fazlası için temel gıda kaynağı olan en önemli tahıl ürünlerinden biridir. Artan dünya nüfusunu sürdürülebilir bir şekilde besleyebilmek adına, tarımsal sulama yöntemlerinin geliştirilmesi ve su kaynaklarının verimli kullanımı üzerine çalışmaların yoğunlaşması gerekliliği giderek artmaktadır. Çeltik bitkisinin sulanan tarım alanlarının %34-43'ünü kullandığı tahmin edilmektedir. Küresel ölçekte su kaynakları hızla azalmaktadır ve çeltik üretiminde ihtiyaç duyulan toplam sulama suyu miktarı; kullanılan çeltik çeşidi, toprağın özellikleri ve ekim yöntemleri gibi çeşitli faktörlere göre farklılık göstermektedir. Bu çalışma, Tesadüf Blokları deneme desenine göre düzenlenmiştir. Çalışmada 2 çeltik çeşidi, 2 farklı sulama yöntemi (Geleneksel ve Alternatif tava ıslatma kurutma) ve 3 farklı ekim yöntemi (Sulu, Kuruya ve Fideleme) seçilmiş ve araştırma üç tekrarlamalı olmak üzere 36 lizimetrede yürütülmüştür. Araştırmada çeltikle ilgili bitki boyu, ana sap kalınlığı, salkım uzunluğu, metrekaredeki bitki sayısı, tane verimi, bin tane ağırlığı, kırıklı randıman ve kırıksız randıman gibi özellikler incelenmiştir. İncelenen parametreler üzerine araştırma konularının istatistiksel olarak etkisi olduğu tespit edilmiştir. Tane verimi açısından su uygulamasında geleneksel sulama ile alternatif ıslatma kurutma sulama yöntemi arasında %25 oranında tane verimin azaldığı tespit edilmiştir. Ekim yöntemleri açısından ise, sulu ekim, kuru ekim ve fideleme yöntemleri birbirini takip etmiştir. Yapılan araştırma sonucunda en yüksek tane veriminin suya ekim yönteminde ve geleneksel sulama ile elde edildiği tespit edilmiştir.

The aim of this study was to compare the type traits of primiparous Holstein-Friesian (HF) and Red-Holstein (RH) cows reared mixed in a private farm in Aydın province, Türkiye. In this study, 120 heads composed of HF and RH primiparous cows were used and the effects of breed, calving year (2023, 2024) and calving age (<26 mo and ≥26 mo) on type traits were also investigated. Five non-linear 100 score traits and 18 linear type traits were measured. The effect of breed on chest width (P<0.01), body condition score (P<0.01), rear legs set angle (P<0.01), hock structure (P<0.05), rear udder width (P<0.01), udder depth (P<0.01), central ligament (P<0.05), rear udder height (P<0.01), fore teat length (P<0.05) and mammary acuity (P<0.01) were found statistically significant and the overall mean scores for these traits were 5.32±0.13, 6.97±0.17, 4.83±0.09, 4.87±0.08, 5.04±0.09, 5.74±0.09, 4.73±0.04, 5.37±0.08, 8.35±0.08, 5.38±0.08 and 7.32±0.17, respectively. Also, the effect of calving year on body depth (P<0.01), udder depth (P<0.05) and rear teat placement (P<0.05) and the effect of calving age on chest width (P<0.05), rear legs set angle (P<0.05) and rear teat placement (P<0.05) were found statistically significant. For non-linear 100 scores, the breed effects on dairy strength (P<0.01), foot & legs (P<0.05), udder (P<0.01) and total score (P<0.01) were significant and the means were 82.30±0.17, 81.63±0.11, 83.98±0.09 and 83.03±0.07, respectively. As a result, the significant breed effect found in some type traits showed that HF and RH genotypes, which differ only in color genes, have been considered and reared as different breeds since the 1950’s, causing significant differences in some type traits of these two genotypes.

Nanoemulsions, characterized by droplet sizes below 100 nm, are increasingly recognized for their applications in dairy technology. They are typically created using high-energy or low-energy methods and enable the encapsulation of functional food ingredients within droplets or at the interface, thereby increasing nutrient bioavailability and physical stability. The demand for nanoemulsions is increasing due to their applications in functional beverages and foods. In dairy-based products such as yogurt, cheese, and ice cream, nanoemulsions play multiple roles by stabilizing them and providing health benefits. They increase the physical stability of milk-based products, extend their shelf life, and improve sensory properties. Nanoemulsions also act as carriers for bioactive compounds, vitamins, and flavors, enriching the nutritional profile and consumer appeal of dairy products. Research on nanoemulsions is advancing due to their superior properties such as improved solubility, enhanced nutrient absorption, and controlled release capabilities. They are used in functional milk drinks, fortified milks, and milk-based supplements, contributing to the physical stability of products and offering health and nutritional benefits. Dairy products can be enriched with various functional ingredients by adding nanoemulsions. This review focuses on nanoemulsion formation and applications of nanoemulsion technology applied to dairy products within the scope of innovative approaches in the dairy industry and includes studies and results on this subject.

Quantitative analyses in biological science are especially important in terms of determining and comparing the geometric properties of biological structures. Stereology and morphometry are two important complementary methods frequently used in this field. Stereology refers to the quantitative analysis of the three-dimensional geometric properties of biological structures. In particular, it is used to determine the criteria such as volume, surface area and length of many cells, organelles and tissues with microscopic properties. In addition, this method allows to obtain information about three-dimensional structures by measurements made on randomly selected sections. Thanks to these techniques, accurate estimates of the general structure can be made with data obtained from certain sections instead of examining biological samples completely. Morphometry, on the other hand, is suitable for examining biological structures in terms of shape and size. It is a suitable method for determining the shape changes of organisms and structural elements. Morphometry digitizes the data by making measurements in the digital environment and performs statistical analysis on these data. Measurements are made more quantitative by volume fraction analysis. The importance of stereology and morphometry in quantitative morphology enables the objective realization of biological structures in quantitative analysis in both methods. These methods thus allow the examination of the material at hand, which is mathematical and statistical. In addition to biology, tissue science Quantitative biology has a special place in three-dimensional studies in histology. This review is particularly concerned with stereology and morphometry, and the aim of the review is to give dimension to a specific topic under investigation, thus providing a good background for diagnostic decision making by strengthening traditional approaches, and to address the contributions of these methods in scientific studies.

This study investigated the effects of boron toxicity and humic substance applications on cotton fiber quality and yield over two consecutive years, targeting boron toxicity issues in soils affected by agricultural and geothermal activities. The experiment evaluated varying concentrations of boron (0.6–1.8–5.4–16.2 mg B l-1) and humic substances (0–200–400 kg ha-1), with a focus on their effects on seed cotton yield, fiber length, fineness, strength, and gin efficiency. In the first year, the highest seed cotton yield was recorded at 452.5 kg da-1 with the B1 application, followed by 428.3 kg da-1 with B2. In the second year, increased boron application led to a notable decrease in seed cotton yield, with the lowest yield at 99.3 kg da-1 for the B4 application. The highest dose of boron also significantly reduced fiber strength, with the lowest recorded at 31.57 g/tex, and gin efficiency, which dropped to 37.98%. Humic substance applications showed limited influence on fiber quality parameters; however, the highest dose (H3) led to a significant increase in fiber strength to 33.47 g/tex in the second year. Cotton leaves accumulated substantial amounts of boron, reaching concentrations of 2048 mg B kg-1 during the flowering period of the second year, suggesting that cotton could serve as a hyperaccumulator in phytoremediation efforts for boron-contaminated soils. The study further determined that cotton can tolerate boron concentrations in irrigation water ranging from 1.8 to 5.4 mg B l-1, making it a viable crop in boron-affected regions. These findings provide critical insights into the potential of cotton as a resilient crop in environments with elevated boron levels, underscoring the need for further research to optimize cotton cultivation under such conditions.

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.

Bu çalışmanın amacı, Mamuşa (Kosova) ve Tekirdağ’da yetiştirilen domates ve hıyarlarda yaygın olarak kullanılan bazı pestisitlerin kalıntılarının ve bazı toksik metallerin varlığının araştırılmasıdır. Çalışma kapsamında Tekirdağ ve Mamuşa’dan toplanan 21 domates ve 17 hıyar numunesinde pestisit kalıntı ve element analizleri gerçekleştirilmiştir. Pestisit etken maddeleri olarak abamectin, acetamiprid, carbendazim, chlorpyrifos methyl, imidacloprid, metaflumizone, propineb ve indoxacarb seçilmiştir. Elemental analizde ise bazı toksik metaller dahil 26 elementin taraması yapılmıştır. İncelenen örneklerin hiçbirisinde maksimum kalıntı limiti (MRL) üzerinde pestisit kalıntısı saptanmamıştır. Acetamiprid domateste 16 örnekte (0,25-267 µg kg-1), hıyarda 10 örnekte (0,30-202 µg kg-1), imidacloprid sadece domateste 5 örnekte (4,38-8,83 µg kg-1), indoxocarb domateste bir örnekte (21,80 µg kg-1), propineb Mamuşa’dan toplanan tüm hıyar örneklerinde (187-1090 µg kg-1) tespit edilmiştir.  Elemental analiz sonuçları incelendiğinde kalay domateste 9 örnekte (10,3-12,8 mg kg-1), hıyarda 2 örnekte (10,9-13,4 mg kg-1), nikel sadece Tekirdağ’dan toplanan birer domates (14,7 mg kg-1) ve hıyar (11,3 mg kg-1) örneğinde tespit edilmiştir. Alüminyum ise analizi yapılan 3 hıyar örneğinde (10,0-36,1 mg.kg-1) tespit edilmiştir. Örneklerin hiçbirinde kurşun, kadmiyum ve civaya rastlanmaması olumlu bir durumdur. İncelenen örneklerde tespit edilen kalıntıların insan sağlığı için risk oluşturacak düzeyde olmadığı ifade edilebilir. Ancak tarımsal üretimde kullanılan su, gübre ve pestisitlerin son üründe kalıntı bırakma potansiyeline sahip olduğunu gösteren örnekler olması, üreticileri iyi tarım uygulamalarını sürdürmeye teşvik etmelidir.

In this study, the specific physicochemical, antioxidant, and antibacterial properties of 20 different rosehip marmalade samples, produced using traditional and commercial methods in the Gümüşhane province and its districts, were comprehensively analyzed. To detect the chemical composition of the rosehip marmalade samples, analyses were conducted for total dry matter, pH, ash, titratable acidity (malic acid %), soluble solids, water activity, and color (L*, a*, b*). Additionally, alongside the physicochemical analyses, the contents of hydroxymethylfurfural (HMF) and sugars (fructose, glucose, sucrose, and total sugar) were also determined. To assess the antioxidant properties, analyses for total flavonoid content, total phenolic content, DPPH (% inhibition), and ABTS (% inhibition) were performed. Furthermore, the antibacterial activities of the rosehip marmalade samples against pathogenic bacterial strains such as Proteus vulgaris ATCC 29212, Enterococcus faecalis ATCC 29212, Klebsiella pneumoniae ATCC 13883, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Salmonella typhimurium ATCC 23566, and Escherichia coli O157:H7 35150 were investigated.

The research was conducted to assess the growth performance of different crossbred sheep at Bangladesh Livestock Research Institute (BLRI), Savar, Dhaka. In the crossbreeding program, Perendale, Dorper and Damara breed were considered as sire and BLRI improved native sheep (BNS) was used as dam. The production performance of assorted F1 progeny were evaluated and compared with BLRI improved native sheep. Data analysis was carried out using Generalized Linear Model (GLM) procedure of Statistical Package for the Social Sciences (SPSS) version 25.0. Each crossbred genotype outperformed native sheep in terms of live weights and Average Daily gain (ADG). The live weights (p<0.001 and p<0.01) and ADG (p<0.001) significantly influenced by genotype except the 6 months live weight. Seasonal effects were found non-significant on live weights and ADG except birth weight (p<0.05). Among the crossbreds, the highest birth weight was found in Dorper crossbred (2.37±0.13 kg) while 12 months live weight was found higher in Perendale crossbred (22.33±0.99 kg), respectively. In case of cumulative growth performance of male, the highest value was found in Damara crossbred while, Perendale crossbred female was found better compared to other crossbred. Major disease frequently occurred in crossbred sheep was diarrhea. The survivability rate (%) of crossbred sheep at lamb (0-3 months of age) and grower (3-8 months of age) stage were 92.55 and 90.8, respectively indicates positive influence on the crossbreeding program. Though, this is very first work regarding crossbred sheep, further research is needed in corporation with other economic trait associated with growth and reproduction to evaluate all the crossbred genotype as well as select a suitable crossbred for the production of commercial market lamb in Bangladesh.

This study was conducted to evaluate university students’ chicken meat consumption preferences and their level of knowledge about chicken production. The survey was conducted with 61 structured online questionnaires using the Kobo-collect Tool Box. The questionnaires were administered online via student WhatsApp groups. Chicken breast meat was the most consumed with cubed meat being the most preferred. The expiration date was the main factor affecting chicken meat purchasing decisions, and the majority of the respondents did not have any preferred cooking method. Heavier meat (>1 kg) and fresh chicken meat were the most preferred with the highest chicken meat consumption of 1-3 times per week. Chicken meat consumption was highest at dinner and in the winter season with viral diseases being perceived as the most dangerous chicken diseases. The Coronavirus outbreak affected the chicken meat consumption of the majority of the respondents and most of them bought meat from reliable sale points. Most of the respondents could differentiate between slow and fast-growing broiler hybrids with Ross 308 being the most recognized commercial broiler hybrid by the respondents. It was concluded that chicken meat consumption was higher among the respondents however, agriculture students should be motivated to improve their knowledge about chicken production.
