Dilruba Erguler | Fatma Okyay | Omer Senol | Caner Yerli
In this study, the effects of different organic matter additives [soil (control), 20 ton ha-1 farmyard manure, 20 ton ha-1 biochar, and 10 ton ha-1 farmyard manure+10 ton ha-1 biochar] to the soil of lettuce grown with different irrigation water levels [100% (full irrigation), 75% (25% deficit irrigation), 50% (50% deficit irrigation), and 25% (75% deficit irrigation)] on water and irrigation water productivity efficiencies and plant characteristics were investigated. Among the organic matter additives, the biochar reduced the amount of irrigation water and actual evapotranspiration of lettuce and increased its marketable yield, thus the highest water and irrigation water productivity efficiencies were obtained from biochar treatment. Despite the decreasing marketable yield in the 50% irrigation treatment, the proportionally decreasing amount of irrigation water and actual evapotranspiration caused the highest water and irrigation water productivity efficiencies to occur in the 50% irrigation treatment. While the root diameter, root fresh and dry weights, stem diameter and length, head fresh and dry weights, marketable leaf number and yield, chlorophyll, and leaf relative water content of lettuce decreased with decreasing irrigation water levels, root length and membrane damage increased. The effects of organic matter additives on all of these physical-physiological properties, except root diameter and membrane damage, were found to be significant, and the biochar provided the most effective development of these parameters under the deficit irrigation regime. Considering that the yield and yield characteristics in 75% irrigation treatment do not decrease at a very significant level compared to full irrigation (100%) and that these decreases can be compensated by biochar and that the farmyard manure+biochar as alternative treatment is also effective in improving the decrease in yield parameters, treatment of 10 ton ha-1 farmyard manure+10 ton ha-1 to the soil at 75% irrigation water level was found to be recommended in lettuce cultivation.

Igor Aksyonov | Marina Kotchnenko
The research methodology was based on determining the soil moisture consumption per unit of photosynthesis productivity, establishing the influence of the moisture consumption coefficient on the productivity of photosynthesis on the yield of sunflower genotypes. The aim of the research was to determine the physiological characteristics of the formation of plant productivity of different sunflower samples and use them in assessing and creating genotypes for cultivation in arid conditions. The conducted investigations allowed to determine physiological factors and properties of plants that determine the level of formation of the weight of seeds of the head and the yield of sunflower. The weight of seeds of the head is determined by the amount of soil moisture consumption per unit of net productivity. Between the indicators of soil moisture consumption per unit of net productivity at the stage of formation of the head - the beginning of flowering, a direct negative correlation interdependence was established. Sunflower varieties with a minimum consumption of soil moisture per unit of net productivity of photosynthesis of 1.01-1.05 m-3 g m-2 per day form in arid conditions of the Steppe of Ukraine the maximum level of weight of seeds of the head of 58.7-78.7 g, which ensures obtaining a high yield within 2.68-3.49 t ha-1. The conducted assessment of genotypes by indicators of soil moisture consumption per unit of net productivity made it possible to create highly productive varieties of sunflower Emelard, Igolya, Orlik.

Efkan Bağda | Didem Duman
This study presents a comprehensive investigation into the interactions of two distinct synthetic dyes—1,9-Dimethyl-Methylene Blue and Toluidine Blue —with different DNA structures, namely calf thymus DNA (ct-DNA), G-quadruplex DNA, and single stranded DNA (ssDNA). The objective of this research is to elucidate the molecular affinities of these dyes for specific DNA structures and explore their potential applications in molecular biology and diagnostics. The experimental approach involved detailed UV-visible spectroscopic analyses, to probe the binding affinities of each dye with ct-DNA, G-quadruplex DNA, and ssDNA. The study aimed to assess the selectivity of these dyes towards the unique structural features of each DNA entity. The binding stoichiometry is defined from Job’s method. The selectivity of the dyes towards DNA also investigated with competitive dialysis experiments. The binding stoichiometry were 1:1 for 1,9-Dimethyl-Methylene Blue and Toluidine Blue and G-quadruplex DNA or ssDNA. Besides, results indicate that 1,9-Dimethyl-Methylene Blue and Toluidine Blue exhibit a pronounced affinity for G-quadruplex DNA, and ct-DNA. While single-stranded DNA is a fundamental component of DNA replication and transcription, our dyes exhibit lower affinity for this structure. The selectivity is advantageous, as it allows for the discrimination between single-stranded and structured DNA regions. The potential applications in studying DNA dynamics and unwinding processes are vast.

Harun Hurma | Emir Can
Since the concept of brand has a wide and diverse range, it is divided into different groups from different perspectives. Local brands are products that are produced, manufactured, and sold by a company in a specific city or that are distributed in a constrained area. This study’s primary goal is to assess how local brands selling milk and dairy products in a particular region are perceived by local consumers. It also seeks to analyze the standing of local producers in this sector and consumer attitudes toward regionally branded goods by highlighting the significance of milk and dairy products in terms of human health. The study makes use of survey information from 381 households in Süleymanpaşa Districts of Tekirdağ-Türkiye. The data were analyzed using fundamental statistical techniques, factor analysis, and logistic regression analysis. In the survey, it was found that 85.0% of participants were familiar with the idea of local brand, while just 15.0% were not. Consumers who said they buy local brand milk and dairy products made up 78% of the sample. Consumers found local products to be more natural and tastier than national brands. According to the factor analysis, the judgements influencing customers’ preference for local brand milk and dairy products were classified into five factors. These factors are named as naturalness and quality, price and promotion, health, food safety, brand and image. Logistic regression analysis was used to explain the association between purchasing local brand milk and dairy products and factor scores, as well as knowing the notion of local brand. Those who favor “Naturalness and Quality” in purchased milk and dairy products are nearly three times more likely than those who do not to purchase local brand milk and dairy goods. With a probability of 68.4%, those who do not understand the notion of local brand will not purchase local branded products.

The present study highlights the ongoing threat of foodborne illnesses to public health, primarily caused by bacterial pathogens. Despite advancements in conventional microbiological testing techniques, which are sensitive but time-consuming, challenges remain in ensuring timely detection of contaminants throughout the food supply chain. The Hazard Analysis Critical Control Point (HACCP) system is recognized as a more effective approach to ensuring food safety, emphasizing proactive identification and control of hazards at critical points in production. Emerging technologies like quantitative polymerase chain reaction (PCR) and biosensors offer faster and more accurate detection methods, although with certain limitations. Biosensors such as ELISA, SPR, and electrochemical immunosensors, in particular, show promise due to their high sensitivity and specificity, enabling rapid detection of a wide range of contaminants. This paper underscores the importance of integrating advanced technologies with established food safety protocols to enhance the safety and quality of food products, benefiting consumers, producers, and regulatory agencies alike.

Yunus Emre Boğa | Nasir Abdallah | Kadriye Kurşun | Mikail Baylan
Diğer hayvancılık kollarında olduğu gibi kanatlı hayvan yetiştiriciliğinde de işletmelerin masraflarının en önemli kısmını yem masrafları oluşturmaktadır. Özellikle, gelişmekte olan pek çok ülkede önemi artan, bulunması zorlaşan ve pahalı hale gelen yem masrafları birçok küçük ölçekli kümes hayvancılığı işletmesinin kapanmasına ve kümes hayvanı üretiminin toplam maliyetinin artmasına neden olmaktadır. Bu durum, kanatlı ürünleri olan tavuk eti ile yumurta fiyatlarının artmasına, gelişmekte olan ve az gelişmiş pek çok ülkede birincil hayvansal protein kaynağı olan kanatlı eti ve ürünlerinin tüketiminin ve alım gücünün düşmesine, yetersiz ve dengesiz beslenme gibi pek çok olumsuz duruma yol açmaktadır. Yem masraflarını düşürmek, dolayısıyla kanatlılardan elde edilen ürünlerin maliyetini azaltmak için alternatif bir yem madde arayışı çok önemlidir. Anavatanı Asya olan Moringa oleifera, besin maddeleri açısından oldukça zengin olan ve soya fasulyesi, mısır gibi geleneksel hayvan rasyonunda kullanılabilen yem maddelerinin bir kısmının yerini alabilecek bitkilerden biridir. Afrika ve Asya’da Moringa oleifera’nın kanatlı performansı ve ekonomik verimlilik üzerindeki etkisini araştıran pek çok araştırma yapılmıştır. Belirli bir oranda Moringa tohumlarının veya yapraklarının rasyona dahil edilmesinin, üretim performansını, et kalitesini, hayvan sağlığını ve refahını artırdığını, ancak daha yüksek miktarlarda kullanıldığında ise hayvanın yaşamını zorlaştırıp, üretim parametrelerinin azalmasına yol açtığı bildirilmiştir. Yapılan çalışmalarda; kanatlı rasyonlarına %5-10 arasında Moringa ilavesinin performansı olumlu etkilediğini gösterirken, rasyona %10’un üzerinde Moringa ilave edildiğinde ise hayvanların performansının kötüleştiğini belirtmişlerdir. Bu derleme, alternatif bir yem maddesi olan Moringa oleifera’nın yapraklarının ve tohumlarının kanatlı hayvanların performansı üzerindeki etkisini belirlemek amacıyla hazırlanmıştır.

Proper nitrogen (N) management is vital for gaining potential yield benefits of a variety. Adjusting transplanting time enables the plant taking benefit from natural conditions favorable for its growth. In light of these, an investigation was carried out in the Boro season at the Agronomy Field Laboratory, Bangladesh Agricultural University from November 2022 to April 2023 to investigate the impact of various transplanting dates and N levels on the yield of Nizershail rice. The study involved four dates of transplanting viz. 16 December, 31 December, 15 January, 30 January and four nitrogen (N) levels viz. 0, 50, 100 and 150% of the recommended dose (RD) of N from urea where the recommended dose was 90 kg urea per ha. The trial was replicated thrice using Randomized Complete Block Design (RCBD). Results showed that the tallest plant, the uppermost grains/panicle and 1000 grains weight were detected in 16 December transplanting and the maximum grain yield was observed in 31 December transplanting. For N, total tillers and effective tillers/hill, grains/panicle, the highest grain and straw yields were found from 100% RD of N and the highest panicle length and sterile spikelets/panicle were found from 150% RD of N. In interactions, the maximum effective tillers/ hill and straw yield were observed from 100% RD of N in combination with 15 January transplanting. The maximum 1000 grains weight and the grain yield were obtained from 100% RD of N in combination with 16 December transplanting. From the result, it may be assumed that to get the maximum yield of Nizershail rice in Boro season could be transplanted between 16 December to 15 January with 100% RD of N from urea.

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.
