An experiment was conducted during Kharif-1 of 2022 at Bangladesh Institute of Nuclear Agriculture (BINA), Substation, Satkhira to know the effect of foliar application of micronutrients (zinc and boron) on the growth and yield of mungbean. There were three levels of zinc (Zn) (0.2%, 0.4%, 0.6%) and boron (B) (0.2%, 0.4%, 0.6%) along with a blanket dose of urea (35 kg ha-1, triple super phosphate (TSP) (80 kg ha-1), murite of potash (MoP) (40 kg ha-1) and Sulphur (60 kg ha-1). The growth and yield of mungbean was significantly affected by foliar application of different levels of Zn and B. Results revealed that foliar application of Zn at the rate of 0.6% and at the rate of B 0.6% along with recommended dose at 45 days after sowing increases the branches/plant, fresh weight (g), dry weight (g), chlorophyll content, flower/plant, pod/plant, seed/pod thereby increase seed yield. Therefore, the foliar spray of 0.6% Zn significantly increased and influenced 1000 seed weight (g), decreased days to flowering, increased number of seed/pod and yield ton/ha along with blanket dose of Urea, TSP, MoP, gypsum might be considered as suitable dose for mungbean production in southern region of Bangladesh.

The aim of the study is to evaluate the ethanol extract of Rheum ribes root (RTE), as well as the root and young shoots (RYSE), for its chemical composition, antioxidant properties and cytotoxic effects. Total polyphenols (TPC), total flavonoid (TFC), radical scavenging activity (DPPH), the ferric reducing antioxidant power (FRAP) of Rheum ribes extracts were determined using colorimetric methods. Mineral contents and vitamin values of samples were determined by ICP-MS and HPLC, respectively. The cytotoxic effect of Rheum ribes extracts was determined on different cells using XTT assay. The cytotoxic effects of RTE and RYSE on cancer cells were evaluated with regard to apoptosis. According to results, mineral contents, vitamine A and C values were very high in both samples. Ethanolic extracts of Rheum ribes young shoot exhibited a selective cytotoxic effect on all cancer cells compared to WI-38 cells, and the IC50 values of the extract in the cancer cells between 26.10 to 54.81 μg/mL. Ethanolic extracts of RTE and RYSE induced apoptosis on MCF-7 cells. The ethanolic extracts of Rheum ribes has effective cytotoxic and antioxidant activity. More research is needed to determine the cytotoxic effect mechanisms on cancer cells.

2023
Mammo Mengesha Erdaw
The aim of this paper was to systematically reviewing the selected feed factors. A worldwide food demand, including animal-derived food is highly predictable to increase at 60% by 2050, particularly in developing countries. By 2030, an annual meat consumption is also estimated to grow from 25.5 to 37 kg per person. In some parts of the world; however, such a growing demand isn’t currently matching with a comparable growth in the local production. For example, by 2050, around 40% of an animal-sourced food could be imported by African countries. Although such insufficiency of an animal-sourced food is generally due to that of the farm-animals’ low productivity, this is specifically believed to be because of the poor quality and inadequacy of the feeds. Both anti-nutritional factors (ANFs) and mycotoxins are the main factors that can contribute to the low quality and less efficiency of the feeds. Although some have beneficial effects, at their low concentrations, anti-nutrients are generally accountable for the harmful effects on the nutrient absorption. For example, up to 50, 23 and 10% of proteins and amino acid digestibility, in non-ruminant animals are reduced by the presence of trypsin inhibitors (TI), tannins and phytates, respectively. Feeds that are toxic for the mono-gastric animals may not be toxic to the ruminants. Soaking/roasting followed by pressure cooking is one of the best treating mechanisms to reduce those of the harmful effects of ANFs. Supplementation of the feeds with typical microbial enzymes, particularly when they are in a combined state enables also to reduce the negative effects of ANFs. A quarter of the world’s crops are being contaminated by the molds and fungi, and hence aflatoxin is an inevitable contaminant. Consequently, when animals eat these contaminated feeds, with aflatoxins the milk, eggs and meat could have the safety concerns to the human consumers. Due to that of some weak regulatory standards, the South-East Asian and sub-Saharan Africa (SSA) countries remain at a high risk of aflatoxin contaminations. In addition to that of the carrying-over impacts of aflatoxins, ANFs and mycotoxins are the main factors that are reducing the feed quality and efficiency, in animal production.

Hatice Tekoğul
Türkiye; birbirinden farklı ekolojik özelliklere sahip olup akarsu ve göller bakımından zengin bir ülkedir. Bazı akarsularımız da yer altına sızarak veya sıcaklığın etkisiyle buharlaşarak kaybolur. En büyük gölümüz Doğu Anadolu'da yer alan sodalı Van Gölüdür. 2021 yılında Türkiye’de su ürünleri üretim miktarı yaklaşık 800 bin ton olup bu miktarın %59’u yetiştiricilik yolu ile elde edilirken %41’i avcılık yolu ile elde edilmektedir. Avcılığın %10’u iç sulardan karşılanırken, yetiştiriciliğin yaklaşık %29’unu oluşturmaktadır. Yapılan bu çalışmada, Van ilinin son 22 yıllık (2000-2021) su ürünleri üretim miktarının elde edilmesi hedeflenmektedir. Bu amaçla Türkiye istatistik Kurumu (TUİK, 2000-2021) veriler yardımı altında Van ilinde yapılan avcılık ve yetiştiricilik yoluyla elde edilen türlerin trend analizi ile 2050 yılına kadar üretim miktarının tahmin edilmesi amaçlanmıştır. Van ilinin 2000-2021 yılları arasında avcılık yoluyla en çok avlanan iç su balıkları türleri sırasıyla; İnci Kefali (Chalcalburnus tarichi), Sazan (Cyprinus carpio), Siraz (Capoeta Pestai), Alabalık (Salmo spp.). Yetiştiriciliği yapılan tür ise sadece Alabalık’tır. Sonuç olarak, Van ilinde avcılık yoluyla elde edilen tatlı su balıkları üretiminde yıllara bağlı olarak genel bir azalmanın varlığı gözlenmektedir. Hatta bu şartlar devam ederse Siraz balığının 2022 yılında üretim verilerinde, Sazan balığının ise 2024 yılında üretiminin sona ericeği tahmin edilmiştir. Bunun yanında yetiştiricilik yoluyla üretilen tek tür olan Alabalık üretiminin artacağı bulunmuştur.

The main focus of this research was to explore the present status of pineapple cultivation in Madhupur tract of Bangladesh. Primary data were collected using a pre-designed and pre-tested questionnaire by face-to-face interviews from a sample of 300 pineapple growers and two focus group discussions were also carried out from March to May 2022. According to the study findings majority (51%) of the respondents cultivate pineapple in their own land having medium experience (53.3%), followed mixed cropping pattern (89%) where 25.33 percent respondent cultivate banana as companion crop. ‘Calendar’ is the top most cultivated variety of pineapple in Madhupur tract. Majority of the respondent use balanced pesticide and ripening agent due to increasing demand of chemical free farm fresh pineapple among consumers. Higher profit compared to other crops (82.00 %) was the main reason for producing pineapple in the study area. Majority (26.67%) of the respondent followed (Grower- Faria- Bepari- Aratdar- Wholesaler- Retailer- Consumers) channel among the six dominant marketing channels to market their produced pineapple. The results of SWOT analysis revealed that weakness of pineapple cultivation in Madhupur tract have the potential to improve. If the government and other policy making organizations come forward to solve the problems arising in pineapple cultivation, then the position of pineapple as fruit will be consolidated soon in home and abroad.

Mustafa Yaşar | Nurettin Baran | Yusuf Güzel Demiray | Remzi Ekinci | Yaşar Karadağ
In this study, seeds of cotton plants were coated with different boron concentrations and their effect on seedling growth was investigated. The experiment was carried out at Muş Alparslan University, Faculty of Applied Sciences, Department of Plant Production and Technologies, under laboratory and greenhouse conditions, according to the Randomized Plots Trial Design with 4 in laboratory and 3 in greenhouse replications, respectively. In the study, Di-sodium tetraborate decahydrate (Na2B4O7.10H20) (M=381.37 g mol-1) with a minimum purity of 99% boron compound have been used in different doses; 0 (control), 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250 and 2500 mg kg-1. According to the results of the regression analysis, it was determined that as the boron dose in the application increased, the root length was positively correlated and other parameters were negatively correlated. In terms of the parameters examined, 250 mg kg-1 Kaolin+liquid K-Humate (15% HA) 400 ml kg-1 (U3) boron application under laboratory conditions showed better results, and 1000 ml kg-1 Kaolin+liquid boron application under greenhouse conditions. It was determined that the application of K-Humate (15% HA) 400 ml kg-1 (U6) promoted growth. In addition, it was found that the results were confirmed in the grouping of the relationships between applications and parameters with heat map clustering and PCA graphs. As a result, it was determined that the toxic range of boron applications applied to the seed in the cotton plant was very narrow, and that it promoted seedling development and root elongation in the U6 application, but it was concluded that the study should also be studied in field trials in order to make more decisive decisions.

Hatice Yaren Kuloğlu | Murat Boydak
The aim of this study is to histologically and histochemically determine the developmental and involutional stages of bursa of Fabricius of henna partridge (Alectoris chukar). In the study, bursa of Fabricius of 12 3-month-old (6 males, 6 females), 12 6-month-old (6 males, 6 females) henna partridges purchased from a private farm were used. It was observed that bursa of Fabricius was surrounded by a connective tissue capsule and consisted of tunica serosa, tunica muscularis, and tunica mucosa layers from the outside to the inside. It was seen that the tunica muscularis consisted of outer longitudinal and inner circular smooth muscle fibers. It was observed that the tunica mucosa made plicae towards the lumen of the organ and consisted of 10-15 plicae. It was seen that lamina epithelialis and lymph follicles were present in each plica. It was determined that the lamina epithelialis consisted of two parts called FAE (Follicle-Associated Epithelium) and IFE (İnter Follicular Epithelium). It was noted that the lymph follicles contained cortex and medulla sections and were separated locally by capillaries together with cortical medullary boundry cells. In the Methyl Green-pyronin staining method, plasma cells were found in the bursa of Fabricius of the henna partridge, in the connective tissue surrounding the organ, around the blood vessels and inside the follicles. In AB pH=2.5 staining, AB-positive reaction was seen only in the apical part of the epithelial cells forming FAE and IFE in the pre- and post-involution period. In PAS staining, PAS-positive reaction was observed only in the apical part of the epithelial cells forming FAE and IFE in the pre- and post-involution period. In PAS/AB pH=2.5 combined staining method, AB-positive reaction was observed only in the apical part of epithelial cells in the pre- and post-involution period. As a result of this study, it was found that bursa of Fabricius of the henna partridge did not undergo any histochemical changes despite its histologically large differences after involution.

Özlem Ete Aydemir | Mehmet Akgün | Halil Erdem | Kürşat Korkmaz | Faruk Özkutlu
Cadmium (Cd) accumulation in durum wheat (Triticum durum L.) and its human transport with food chain is a major environmental issue worldwide. The research was based on a pot experiment conducted on fifteen durum wheat cultivars, grown on acid soil pH 5.2. The effect of application of two different lime form (lime1=CaO; Calcium oxide and lime2=CaCO3; limestone) and on shoot dry weight and shoot concentrations of cadmium (Cd). Durum wheat cultivars were grown in strongly acid soil pH 5.2 treated with control (lime0), lime1 (CaO3 g kg-1 soil), lime2 (5.36 g CaCO3) and Cd (5 and 10 mg kg-1 soil) and harvested after 62 days of growth under greenhouse conditions. Durum wheat cultivars without lime fertilization caused decrease in shoot growth, in all durum wheat cultivars and at high Cd treatment. On the other hand, application of lime to the soil resulted in an increase in dry matter yield at both Cd5 and Cd10 doses. While average shoot dry matter yield of lime0 conditions of cadmium 10 dose was 47 mg plant-1, this yield increased to 120 mg plant-1 in lime1 application and to 111 mg plant-1 in lime2 application. Shoot Cd concentrations of durum wheat varieties caused a statistically significant decrease with lime1 and lime2 applications, whereas lime0 and lime2 applications of Cd5 dose caused 46% and 30% decrease in average Cd concentrations, respectively. The results indicated that all durum wheat cultivars were more susceptible to both without lime and Cd toxicity as compared to lime treatment. Cadmium toxicity in the shoot was relieved by lime1 and lime2 treatment. The results indicate that lime protects plants from Cd toxicity in durum wheat cultivars.

Murat Karahan | Seyda Şahin | Mahmut Niyazi Moğulkoç | Recep Kalın
Staphylococcus aureus (S. aureus) insanlarda ve hayvanlarda patojen bir tür olup, dünyadaki gıda kaynaklı zehirlenmelerin en önemli nedenlerinden biridir. Bu çalışmada farklı hayvan türlerine (sığır, koyun, keçi ve tavuk) ait etlerde ve gıdaların temas ettiği yüzeylerden elde edilen örneklerde S. aureus’un koagülaz (coa), clumping faktör (clfA) ve protein A (spa-IgG; spa-X) gibi önemli virülens genlerinin moleküler yöntemlerle karakterize edilmesi amaçlandı. Bu amaçla Sivas ilindeki çeşitli işletmelerden et (n=400) ve yüzey svap (n=50) örnekleri toplandı. Örnekler fenotipik yöntemlerle koagülaz pozitif S. aureus olarak identifiye edildi. Koagülaz pozitif olarak doğrulanan izolatlara ait virülens genleri tekli ve mültipleks Polimeraz Zincir Reaksiyonu (PZR) ile incelendi. Toplamda 450 örneğin 110’unda (%24,4) S. aureus belirlendi. Bu izolatların %29, %24, %14, %32 ve %22 oranlarında sığır, koyun, keçi ve tavuk et örneklerinin yanı sıra yüzey örneklerinde de bulundu. S. aureus izolatlarının tamamında coa, clfA, spa’nın IgG bağlayan bölgesi ve X bölgesini kodlayan genler tespit edildi. Bu dört gen bölgesinin ikisinde polimorfizmler gözlendi. Coa-PZR’da, izolatların tamamında beş farklı moleküler uzunluğa sahip ve 500-1400 bç arasında değişen tek bir bant oluşumu bulundu. spa-X-PZR’da ise izolatların tamamında yedi farklı moleküler uzunluğa sahip ve 190-350 bç arasında değişen tek bir bant oluşumu belirlendi. Sonuç olarak, et ve yüzey orijinli S. aureus izolatlarında coa-PZR ile spa gen polimorfizmleri tespitinin geleneksel yöntemlere karşı iyi bir alternatif olarak kullanılabileceği, dolayısıyla stafilokokal enfeksiyonlara karşı etkili kontrol stratejilerinin geliştirilmesi ve halk sağlığının korunmasına katkı sağlayacağı düşünülmektedir.
