2023
Ankita Poudel
The study about the economic returns of cowpea (Vigna unguiculata) by the use of rhizobium seed inoculation and different phosphorus doses was conducted at Bharatpur, Chitwan, from February to May 2022. The experiment was conducted in a two-factor randomized complete block design (RCBD) with three replications and eight treatments. Treatments were set as factor A: seed inoculation i.e., un-inoculated and inoculated; and factor B: four different phosphorus doses (20, 40, 60, 80 kg ha-1). The cowpea variety ‘Prakash’ was used. Results revealed that the application of seed inoculation provides the highest returns compared to an un-inoculated one; similarly, in case of phosphorus dose of 40 kg P2O5 ha-1 gives the maximum economic returns compared to other phosphorus doses. Furthermore, the interaction of rhizobium inoculation with 40 kg ha-1 gives the highest gross income (NRs. 216005), net return (NRs. 110829.39) and B: C (2.05) compared to all other single inoculation or phosphorus or interaction treatments ( 1 $ = NRs. 132.53) . From the result, it is concluded that the use of rhizobium inoculation along with 40 kg P2O5 ha-1 would be economically profitable for the farmers under the Terai conditions of Nepal.

Bu çalışma, Eskişehir Geçit Kuşağı Tarımsal Araştırma Enstitüsü (EGKTAE) Tavuk Islah işletmesinde ıslahı gerçekleştirilen 2 saf baba (B1 ve B2) ile 3 saf ana (A1, A2 ve A3) hattında 14-42 haftalar arasında yürütülmüştür. Tüm saf hatlarda artan yaşla birlikte FPD skorlarında artış görülmüştür. Canlı ağırlıkların daha yüksek olduğu baba hatlarında (B1 ve B2) 14 haftalık yaşta daha düşük FPD skorları görülürken, 42 haftalık yaşta ana hatlarından (A1, A2 ve A3) daha yüksek olmuştur. Ana hatlarında 30 ve 42 haftalık yaşlarda baba hatlarına göre daha yüksek yumurta verimi ve kuluçkalık yumurta verimi elde edilmiş ve hatlar arasındaki farklılıklar önemli bulunmuştur (P<0,01). Yumurtlama döneminde A1, A2, A3, B1 ve B2 saf hatlarında gerçekleşen kuluçkalık yumurta oranları sırasıyla %98,55, %96,68, %97,75, %96,39 ve %97,23 olarak belirlenmiştir. Saf hatlarda yumurta ağırlıkları bakımından farklılıklar önemli bulunmuştur (P<0,01). Döllülük oranları bakımından genotipler arasında önemli farklılıklar belirlenmiştir (P<0,01). Ebeveynlerin 14, 20, 30 ve 42 haftalık yaşlarındaki canlı ağırlıkları ile FPD skorları arasında belirlenen korelasyon katsayıları sırasıyla 0,70, 0,64, 0,72 ve 0,67 bulunmuştur (P<0,01). 42. hafta yumurta verimi ve kuluçkalık yumurta verimi ile FPD değerleri arasında -0,56 ve -0,54’lük korelasyon katsayıları belirlenmiştir (P<0,01). Döllülük oranları ile canlı ağırlıklar arasındaki korelasyon katsayıları önemli bulunmamıştır. Canlı ağırlıklar ile yumurta verimi ve kuluçkalık yumurta verimi arasındaki önemli düzeyde negatif yönlü korelasyonlar bulunmuştur (P<0,01). Sonuç olarak, CA ve FPD düzeyleri baba hatlarında daha yüksek bulunurken, KYV bakımından ana hatları üstünlük sağlamıştır. Artan CA ile FPD düzeyindeki artış üreme performansındaki düşüşe katkı sağlamış olsa da döllülük oranı üzerinde olumsuz bir etki ortaya çıkmamıştır.

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.

Agricultural support is a crucial way to overcome the difficulties of long agricultural production process, lack of capital and low productivity. Moreover, the fact that increasing the supply is not possible in a short while makes agricultural support more important. Different agricultural structures of countries imply different agricultural support values. This paper examines the simultaneous relations between agricultural support and agricultural value added in the six developing countries with the highest agricultural production value. Simultaneous equation systems are estimated by Two-Stage Least Squares method using annual data for the 2002-2018 period. The findings suggest that there is a simultaneous positive and statistically significant relationship between agricultural value added and agricultural supports.

Fadime Beyazyüz | Şemsettin Kulaç
Küresel ısınma nedeniyle ortaya çıkan su kıtlığı ağaçların büyümesini ve gelişmesini sınırlayarak kuraklık stresine neden olmaktadır. Türkiye’de doğal olarak yetişmekte olan Fagaceae familyasına ait kestane (Castanea sativa) kuraklıktan etkilenmektedir. Bu çalışmada Türkiye’nin Akdeniz bölgesinin üç farklı popülasyonundan (Akseki, İbradı ve Selge); Ege bölgesinden (İzmir-Ovacık), Marmara bölgesinden (Bursa) ve Karadeniz bölgesinden (Düzce) toplanan C. sativa tohumlarından elde edilen fidanlar kullanılmıştır. Sera ortamında farklı sulama rejimlerine tabi tutulan üç yaşında (3+0) kestane fidanlarının kuraklık stresi altındaki yaprak gaz değişim parametreleri [net asimilasyon (fotosentez) oranı (A), stoma iletkenliği (gs), terleme miktarı (E), içsel su kullanım etkinliği (iWUE=A/gs) ve anlık bitki su kullanım etkinliği (WUE=A/E)] ve prolin birikimine etkisi araştırılmıştır. Sonuç olarak, bütün popülasyonların E, A, gs değerlerinin kontrol gruplarına göre önemli ölçüde azalmasının yanı sıra prolin birikiminin kontrol gruplarına göre arttığı gözlenmiştir. Sonuç olarak altı farklı C. sativa popülasyonlarının kuraklığa adaptasyon potansiyellerinin değişkenlik gösterdiği ancak Akdeniz popülasyonlarının kuraklığa adaptasyon potansiyellerinin daha yüksek olabileceği gözlenmiştir.

The purpose of this study was to determine the effects of selenium, vitamin E, vitamin A, and vitamin D3 treatments on reproductive parameters in Awassi sheep fed solely dry grass and grain stubble during the breeding season with estrus synchronization. Seventy-five sheep were implanted with intravaginal sponges containing 20 mg of flugestone acetate for 9 days for estrus synchronization. On the day the sponges were inserted, the first group received an intramuscular injection of a supplement containing 200,000 IU of vitamin A, 30,000 IU of vitamin D3, and 20 mg of vitamin E, as well as a supplement containing 1 mg of sodium selenite and 60 mg of vitamin E. The second group was the control group, with no supplementary vitamin injected. On the day of sponge removal, the sheep received intramuscular injections of 500 IU PMSG and 250 mcg cloprostenol sodium in both groups. The sheep in the first group were given a second injection of the supplement on the same day that contained 20 mg of vitamin E, 30,000 IU of vitamin D3, and 200,000 IU of vitamin A. The sheep that showed signs of estrus were mated naturally after the estrus synchronization. Estrus rates were 86.11% and 85.29%, conception rates were 74.19% and 58.62%, pregnancy rates were 63.88% and 50%, lambing rates were 100% and 100%, and litter size was found to be 126.08% and 123.52% in Group I and II, respectively (P=0.858). Although there was no significant difference in the reproductive characteristics between the groups (P>0.05), Group I had a greater pregnancy rate and litter size. During the breeding season, it is believed that the regular application of vitamin and mineral supplements on a program basis in sheep fed only dry pasture and grain stubble contributed to fertility.

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.

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.
