This study aimed to determine the tachinid parasitoids (Diptera: Tachinidae) associated with different hemipteran hosts in Bolu and Düzce provinces in the Western Black Sea region of Türkiye in the period from 2022 to 2024. For this purpose, samples of Hemiptera were collected from various weeds, shrubs and cultivated plants. These specimens were brought to the laboratory and cultivated on the corresponding host plant material at 25 ± 2 °C and 60-70% RH. In this study, three different parasitoid species of tachinids were identified on three different hemipteran hosts. Of these, Graphosoma lineatum Linnaeus (Hemiptera: Pentatomidae) is a new host record for Ectophasia crassipennis (Fabricius, 1794) and Gymnosoma clavata (Rohdendorf, 1947) (Diptera: Tachinidae) from Türkiye. In addition, information on the hosts of the parasitoids parasitoids in Türkiye is presented.

The aim of this study was to investigate the growth of C. sporogenes in model white cheese stored under cold conditions (4°C) and in vacuum packaging and its effect on quality parameters. For this purpose, two different cheeses were produced, contaminated (CMBP) and not (MBP) with C. sporogenes 73 and C. sporogenes 97 strains, and physicochemical, microbiological and volatile component analyses were performed every 15 days during the 60-day storage period of the cheeses. No significant difference was detected in dry matter (%), fat in dry matter (%), and protein (%) contents of cheeses during storage. As an important finding, C. sporogenes did not affect the acidity values (pH and % acidity). The pH and % acidity values of the cheeses were found to be 4.79±0.03 – 4.98±0.05 and 2.04±0.06 – 2.16±0.06, respectively. When the microbiological results were examined, the total mesophilic aerobic bacteria (TMAB), lactococci and lactobacilli counts of the cheeses decreased during storage, while the yeast-mold counts did not change. There was no change in CMBP cheese with an initial C. sporogenes spore count of 4.62±0.11 during storage. When the color parameters of the cheeses were examined, a difference was detected in the L* value and was lower in CMBP. At the end of storage, there was no change in the a* values of the cheeses, while the b* values decreased. It was determined that there were differences in the aromatic compounds of the cheeses and while the contents of acetic acid, butyric acid and acetoin, which are LBD indicators, were found to be 32.34%, 17.17% and 17.82% in CMBP cheese, butyric acid was not detected in MBP cheese. The results showed that C. sporogenes survived for a long time in white cheeses stored at pH values below 5 and at low temperatures and could cause the LBD on its own.

Marketing information enhances farmer’s decision to increase production and productivity of agricultural commodities. This paper examines farmers’ perspectives on agricultural marketing information in developing countries, with a case study focusing on three districts in Tanzania. Data were obtained from a survey conducted on 291 maize farmers in the three districts namely Arusha (103 farmers), Njombe (100 farmers) and Kongwa (88 farmers), selected from three regions in Tanzania Mainland. Descriptive statistics were used to analyse the percentage distributions of the farmers based on socio-economic characteristics and Likert scale ratings of the farmers’ levels of agreement with the debriefing questions constructed to evaluate their perceptions. The analysis of the socio-economic variables of the farmers suggests male dominance in maize farming, predominant youthful farming demographics, predominantly large household Size, and predominance of low-level educational backgrounds among maize farmers in the study areas. The results of the socio-economic characteristics underscore the importance of targeted policies to support maize farmers, focusing on education, youth engagement, and household resource management. The overall result of farmers’ perceptions of agricultural marketing information indicates a widespread agreement across districts highlighting the shared challenges and priorities among maize farmers in Tanzania, particularly indicating that farmers recognize the benefits of agricultural services and understand the importance of communication infrastructure for economic development. The study thus, recommends establishment of local marketing information centers to reduce costs and time associated with gathering market information, enhancement of digital literacy to train farmers, and collaboration with critical stakeholders; such as government, private sector, and non-profits organizations to fund and sustain marketing information infrastructure for farmers. Investments in communication and marketing infrastructure will bridge information gaps, enhance market access, and ultimately drive economic development among maize farmers. This structured approach will not only improve maize farmers’ productivity but also contribute to broader rural development goals.

Araştırmada farklı illerdeki topraklardan izole edilmiş bakterilerin kadmiyum (Cd) ile kirletilmiş topraklarda yetiştirilen mısır bitkisinin gelişimi ve besin elementi alımına etkilerini belirlemek amaçlanmıştır. Sera koşullarında yürütülen çalışmada 3 kg kapasiteli saksılar kullanılmış ve tesadüf parselleri deneme desenine göre üç yinelemeli olarak saksı denemesi yürütülmüştür. Araştırmada Ordu (B1), Hatay (B2), Sivas (B3), Adana (B4), Isparta (B5) ve Antalya (B6) illerinden izole edilmiş bakteriler kullanılmıştır. Kadmiyum uygulamaları 0 mg Cd kg-1 ve 5 mg Cd kg-1 olarak uygulanmıştır. Araştırma sonuçları, bakteri uygulamalarının mısır bitkisinin kuru madde üretimini arttırdığını ve en yüksek kuru madde üretiminin 57,6 g saksı-1 ile Cd0 uygulamasında B2 aşılamasında olduğunu göstermiştir. Araştırmada hem Cd0 hem de Cd5 uygulamasında bütün bakteri aşılamaları kontrole oranla bitkinin kuru madde üretimini arttırmıştır. Aynı durum azot (N) konsantrasyonu için de geçerlidir. Araştırmada ortalama değerler incelendiğinde, fosfor (P), kalsiyum (Ca), demir (Fe), bakır (Cu), mangan (Mn) ve çinko (Zn) konsantrasyonları özellikle Cd ile kirletilmiş topraklarda bakteri aşılaması ile bitkide artmıştır. Bu durum, Cd ile kirlenmiş topraklarda bakteri aşılaması ile bitki yetiştirmenin önemli bir strateji olabileceğini düşündürmektedir.

This study aimed to determine the effects of the addition of different doses of Lactobacillus brevis to oat silage on the physical and chemical properties, aerobic stability, in vitro organic matter digestibility, and energy value of the silage.  In the study, the treatment groups were oat control (OC), 1x106 (Lb6), 1x108 (Lb8) and 1x109 cfu/kg dry matter (Lb9) L. brevis inoculated oats. Inoculation of L. brevis into oat silage increased the number of lactic acid bacteria and decreased the pH of the silage at the time of opening. This inoculation decreased the organic matter, acid detergent fiber and neutral detergent fiber contents of the silages at opening compared to those of OC, while increasing the dry matter and crude protein contents. The L. brevis inoculation into oat silage decreased the pH values and yeast counts on the fifth day after opening the silages compared to OC, without affecting the amount of CO2 production and mold count. The inoculation did not affect the in vitro organic matter digestibility and metabolizable energy value of silage; but increased the net energy lactation value compared to OC. When the L. brevis doses are evaluated independently, it can be said that 1*108 and 1*109 cfu/kg DM doses contributed more effectively to oat silage, so any of these doses can be preferred.

Bu çalışmada ülkemiz ve dünya genelinde uzun yıllardır yaygın bir şekilde tüketilen erişteye belirli oranlarda ve farklı formlarda ilave edilen çörek otu, kekik ve zerdeçalın, eriştenin bazı kalite özelliklerine etkileri araştırılmıştır. Üretimde kullanılan tane çörek otu, toz çörek otu, yaprak kekik ve toz kekik formülasyona %1, %2, %3 ve %4 (ağırlıkça); zerdeçal ise %0,5, %1, %1,5 ve %2 (ağırlıkça) oranında ilave edilmiştir. Baharatların ilavesi ile üretilen eriştelerin nem içeriklerinin genel olarak azaldığı, % kül içeriklerinin tane ve toz kekik içeren eriştelerde, % protein içeriklerinin ise tane ve toz çörek otu içeren eriştelerde artış gösterdiği tespit edilmiştir. Eriştelerin renk değerleri (L*, a*, b*) baharat ilavesine bağlı olarak değişiklik göstermiştir. Erişte formülasyonuna ilave edilen baharatlar L* değerlerini düşürerek eriştelerin parlaklığını azaltmış ve özellikle zerdeçalın yüksek a* ve b* değerinden dolayı daha sarı renkli erişteler elde edilmiştir. Erişteye artan oranlarda baharat ilave edilmesi ile optimum pişme süresi (dk), su absorpsiyonu (%) ve hacim artışının (%) kontrol eriştesine göre azaldığı, pişme kaybının (%) ise arttığı belirlenmiştir. Genel kabul edilebilirlik açısından kontrol eriştesi duyusal analizlerde en yüksek puanı almıştır. Erişteye katılan baharatların ilave oranı arttıkça, duyusal ve pişme özellikleri olumsuz yönde etkilenmiştir. Bu sebeple eriştenin çalışmada değerlendirilen özellikleri bozulmadan, kabul edilebilir bir şekilde bu baharatlarla zenginleştirilebilmesi için en fazla %2 oranında çörek otu ve kekik; %0,5 oranına kadar zerdeçalın başarı ile kullanılabileceği sonucuna varılmıştır.

Türkiye has 27% of the World’s Papaver species in its flora, and 15 of them are endemic. Poppy (Papaver somniferum L.) is the most cultivated and economically significant species of the Papaver genus. There is a need to study and exploit other Papaver species as well. Poppy is an important strategic plant with a history dating back to 5000 BCE and records of its being valued in the lives of different civilizations, art archives, food (seed), and medicine (opium gum). Although opium gum and seed have been produced for centuries in today’s Türkiye, its cultivation was banned between 1971-74. Years of opium gum experience were destroyed, and after 1974, alkaloid production began to be obtained by processing the dry capsule (unscratched). Today, it is counted as one of the two traditional legal poppy-producing countries in the world. It has the largest legal poppy cultivation area, capsule processing, and alkaloid production factory in the world. The seeds and alkaloids are obtained from the same plant. Türkiye has one of the largest morphine stocks in the world and is capable of meeting 25% of global morphine demand. However, it is insufficient in the production of different alkaloids (noscapine, thebaine, codeine). Seed production is, on average, 20,000 tons, and the capacity has the potential to increase to 40,000 tons with appropriate agricultural techniques.

This study analysed fisherfolk’s poverty and food insecurity status in the coastal region of Nigeria. Data from 420 artisanal fisherfolk, selected through a multistage sampling procedure, were analysed using descriptive statistics, a multidimensional poverty index approach, a household food insecurity access scale, and Seemingly unrelated regression equation (SURE). Findings from the study showed that about 62% of the respondents lived in households with malnourished individuals, no clean water, no electricity, no education, a dirty floor, inadequate infrastructure, and poor healthcare services. Infrastructure such as markets and road networks had the highest contribution to the poverty intensity with education having the least contribution in the study area. The results revealed that artisanal fisherfolk who are non-poor are more food secure than those who are poor. Also, estimates from SURE show that household size, daily income, and owning a house significantly influenced household food insecurity level, while multidimensional poverty level was significantly influenced by age, education experience, daily income, owning a house, and credit constraint. It is, therefore, recommended that initiatives that address poverty and food insecurity issue among the artisanal fisherfolk in the coastal region of Nigeria should be given utmost priority because of the contribution of the sub-sector to the economy. Also, artisanal fisherfolk are encouraged to diversify their means of livelihood in order to reduce their level of poverty.

Phosphorus is essential for plant growth, but mishandling phosphorus-rich waste can harm the environment. This study assessed inorganic phosphorus from fruit and vegetable dumpsite soils and its relation to soil properties. Fifteen (15) soil samples were collected and homogenized into five (5) representative samples each from the dumpsites at depths of 0-15cm, 15-30cm, and 30-60cm and were analyzed for calcium-bound phosphorus (Ca-P), reductant soluble phosphorus (RS-P), Fe-bound Phosphorus (Fe-P), aluminium-bound phosphorus (Al-P), and Soluble/loosely bound P. The data obtained was analyzed using the student’s t-test to compare the different fractions in fruit and vegetable dumpsite soils. The results showed no significant differences between fruit and vegetable dumpsite soils in all the inorganic P fractions. However, vegetable dumpsite soils recorded higher soluble P, Al-P, Fe-P, RS-P, and Ca-P levels of 11.65, 36.29, 41.95, 40.75, and 41.35 mg/kg, respectively. These values were not significantly different from 9.75, 34.01, 39.28, 37.11 and 41.03 mg/kg recorded by fruit dumpsite soil for soluble P, Al-P, Fe-P, RS-P and Ca-P respectively. Results also revealed that reductant soluble P, Calcium bound P, and Na+ with an R2 value of 0.88 had a combined significant influence on the concentration of soluble P. However, the concentration of the inorganic P fractions for vegetable dumpsite soil is in the order; Fe-P> Ca-P>RS-P>Al-P>soluble P, while that of fruit dumpsite soil is in the order; Ca-P>Fe-P> RS-P>Al-P>soluble P. Soluble phosphorus significantly impacts eutrophication due to its rapid release into water. However, low levels of soluble P in fruit and vegetable dumpsite soils are not a major concern. In vegetable dumpsite soil, Fe-P would pose a greater threat during anoxic events while, in fruit dumpsite soil, Ca-P would contribute more to eutrophication due to its high concentration in this soil, especially in alkaline conditions.

Different mechanization practices are included in the drying process, which is among the methods (ensiling, drying, storing at high moisture level, etc.) used in the preservation of roughage, which has an important place in the nutrition of ruminant animals. Haymaking processes are applied by natural (at the field) or artificial drying methods (in warehouses and special dryers). During drying, the hay may be loose or loosely baled. The machines that can be used in various stages of haymaking from harvesting forage to filling the warehouse can be listed as strimmers, crushers, windrow harvesters, hay rakes, loose forage harvesters, balers, bale collecting and transporting machines. These mechanization practices have positive and negative aspects relative to each other. In other words, these mechanization practices affect hay quality at different levels. In this study, different mechanization practices applied in hay drying and the effects of these mechanization practices on hay quality were emphasized.
