In this study, the dynamism of forest areas was tried to be determined by determining the ecological differences between the areas where Fagus orientalis Lipsky. (Eastern beech, Fagaceae), a very important species for forestry in Turkey, and the soils of agricultural fields. lime %, total salt %, pH, texture, field capacity %, C%, N%, C/N ratios, 30-day carbon mineralization of the lands of Eastern beech forests and agricultural fields, which are naturally formed in Sivas province Koyulhisar district, under controlled conditions (28°C, 80 humidity %) was determined by the respiration method, and two areas in two different ecosystems were compared. When the carbon mineralizations of eastern beech soils were examined seasonally, it was determined as 19.54>18.23>17.87>17.18 mg C(CO2)/100g DS/30 day in spring>autumn>summer>winter seasons, while it was determined as 14.46>13.87>13.68>13.65 mg C(CO2)/100g DS/30 day in autumn>summer>spring>winter seasons in agricultural soils, respectively. Significant relationships were found between the C%, N%, 30-day carbon mineralization cumulative values and % carbon mineralization rates between both areas.

Türkiye’nin mevcut doğal çayır-mera alanları ile yem bitkileri ekim alanlarından üretilen toplam kaba yem 73,7 milyon büyük ve küçükbaş hayvan varlığının kaba yem gereksinimini karşılayamamaktadır. Türkiye’de 14,6 milyon hektar doğal çayır-mera alanı bulunmaktadır. Bu alanın büyük çoğunluğunun ot verimi ve kalitesinin artırılması ve sürdürülebilirliğinin sağlanması için ıslahı gereklidir. Bu alanların ıslahı için toplamda 45,6 milyar TL bütçeye ve yıllık bakım için ortalama 4 milyar TL’ye ihtiyaç olduğu hesaplanmıştır. 4342 sayılı Mera Kanunu ile birlikte başlatılan Mera Islah ve Amenajman Projeleri ile bugüne kadar ıslah edilen mera alanları oldukça yetersizdir. Ayrıca, ıslah edilen mera alanlarının otlatılmasında mera idaresinin teknik kurallarına uyulmamasından dolayı yapılan ıslah işlemi sürdürülebilir olmamaktadır. Mevcut bütçe kaynaklarının yeterli olmaması ve devlet imkânları ile mera ıslahının uzun yıllar sürecek olması nedeniyle sürdürülebilir mera ıslahında yeni bir bakış açısına, politika değişikliğine ihtiyaç vardır. Bu çalışmada Türkiye meralarının etkin ıslahı ve sürdürülebilir kullanımı için bazı ıslah ve kullanım modelleri tartışılmıştır. Yapılan öneri ile kıraç meralardan 1000 dekardan taban meralarda 500 dekardan daha büyük orta malı meraların özel sektöre kiralanarak “ıslah et-işlet” sistemiyle ıslah edilmesi ve özel sektör tarafından ıslah edilen alanın ¾’ünün ıslah eden özel sektör, ¼’ünün ise meranın tahsisli bulunduğu köydeki hayvan sahipleri tarafından kullanımın sağlanması önerilmiştir. Kıraçta 1000 dekar, tabanda 500 dekardan küçük alana sahip mera alanlarının ise tahsisli bulundukları yerleşim yerindeki Mera Yönetim Birliklerine kiralanarak ıslahı ve sürdürülebilir kullanımının sağlanması önerilmiştir. Mera Yönetim Birliklerinin ıslah amaçlı kiralamaya istekli olmadığı durumlarda mera alanının büyüklüğüne bakılmaksızın meranın özel sektöre kiralanması önerilmiştir.

Minerals have crucial roles in terms of vital function in the organism including hormones, enzymes, cell formation etc. Oxidative stress and related hormones, regarding infectious diseases, affect all functions of body including mineral taking, metabolism and excretion. The purpose of this study was to investigate the effect of the pox disease on blood minerals composition of sheep and lambs. This study was conducted on 20 healthy sheep, 20 poxvirus infected sheep and their lambs (Totally 80 subjects). One-shot blood samples from sheep and lambs were collected and serums were separated immediately. Serum mineral levels were analysed in the atomic absorption spectrophotometer. In general, the level of Cu in infected animals was higher than in healthy ones. Zn, Fe, Mg and Na levels of healthy animals were found higher than infected subjects. The difference between healthy and infected animal groups for serum Ca and K levels was not significant. Positive correlations were found between serum Zn, Fe, Mg and Na levels. However, a negative correlation was found between Cu-Zn and Cu-Fe pairs. Consequently, Cu, Zn, Fe, Mg and Na levels in serum, which are vital for animal organisms, showed significant changes in sheep and their lambs during poxvirus infection. To rapid healing or prevention of the diseases, mineral disorders must be corrected urgently.

The interactions between plant, soil, and mycorrhizal fungi are ecologically and agriculturally beneficial systems. Mycorrhizal fungi are capable of forming a symbiosis with the roots of many plants in nature. In this symbiosis, the plant receives help from the mycorrhizal fungus in nutrient and water uptake. On the other hand, the mycorrhizal fungi supply the assimilant products they need from the plant. In addition to the many benefits of AMF, they have very important roles in carbon (C) storage in the soil. These roles of AMF are associated with the production of a substance named “Glomalin”. Glomalin, an N-linked glycoprotein that is considered to be AMF gene products, is defined as a protein secreted by AMF hyphae and spores. Glomalin significantly reduces the degradation of soil organic matter by preserving unstable compounds in soil aggregates. Glomalin, which helps soil aggregation, is also an excellent hyphae protector.

Uncertain heat shock by a rapid increase in temperature particularly at the critical growth stage affects plant productivity. The study aimed to assess qualitative changes in wheat grains when plant exposed to high temperature shock (HTS) at starting anthesis for limited durations (48, 72 and 96h). Selected wheat cultivars (Pirsabak-2005, Pakhtunkhwa-2015, Pakistan-2013, DN-84, P-2, P-12 and P-18) were exposed to extending HTS effective from anthesis in the field covering plants within plastic tents for a limited duration. The experiment was conducted in 2017-18 and 2018-19 at the Research Farm, the University of Agriculture Peshawar, Pakistan in a randomized complete block design, in three replications. Temperatures inside and outside plastic tents were manually noted. Two years mean data showed significant effects of HTS on the wheat grain quality. Imposed HTS for 48, 72 and 96h resulted in a reduction on grain amylose by 23, 39 and 48% and wet gluten by 16, 25 and 36%, respectively when compared with the control (i.e. no HTS). Contrary to this, as compared to the control treatment an increase noted in the grain amylopectin by 7, 11 & 17% and in the grain N-content by 13, 28 & 41% with imposing HTS extending to a duration of 48, 72 and 96h, respectively. The study concluded adverse effects of HTS at the anthesis stage on wheat grain quality disturbing amylose and amylopectin ratios, which latter on brought changes in floor structure and gluten elasticity. However, cultivar did differ to respond to the changes but have the option to choose the best one.

Food additives are used to protect food, increase quality and extend shelf life in many stages, from production to consumption of food. Colorants added by food producers to color food or to adjust the color to desired level are among the commonly used food additives. Considering today's developing production technologies, foods fade or discolor at various stages of processing, storage, and sale due to physical and chemical conditions such as heat, light, pH and oxygen. Colorants are used to regain these color losses, to enhance weak colors, to give color to the food that is actually colorless, and to win back the favour of customers by hiding low quality. Therefore, the most used food colorants in Canada, China, European Union, Mexico and United States of America were presented. The chemical name, chemical structure, common uses, acceptable daily intake (ADI), and toxicity literature of six most used artificial food colors were reviewed.

Vermicompost fertilizers have started to attract attention in agriculture last years. Various liquid vermicompost fertilizers are produced and used in agriculture and some of them known as vermiliquer, vermi leachate, vermi tea or vermicast with little differences. This study is aimed to determine the effects of foliar application of liquid vermicompost fertilizer on yield and some yield components on some Turkey triticale varieties under Central Anatolian conditions in Kırıkkale province during the growing period 2014-15 and 2015-16. Six different (control, 75, 150, 250, 350 and 450 cc da-1) liquid vermicompost fertilizer doses were applied by the foliar spraying method at the beginning and end of March in both years to the five Turkey triticale varieties (Alperbey, Mikham 2002, Tatlıcak 97, Karma 2000 and Ümranhanım). According to the results, plant height, grain number and grain yield in spike, grain yield per decare, harvest index and protein content results were found to be significant in fertilizer × variety × year interaction. There is also a statistically significant difference between thousand-grain weight and the variety x fertilizer doses interaction, and between varieties and fertilizer doses in terms of spike length. The positive effects of liquid vermicompost fertilizer doses, except 450 cc da-1, were determined in varieties. It was observed that a satisfactory yield can be obtained from 250 cc da-1 in the absence of nitrogen fertilizers as the top fertilizer. It could be deduced that 250-350 cc da-1 doses of vermicompost fertilizer can be applied in triticale based on varying ecological conditions and varieties in Central Anatolian ecological conditions.

Banana is a fruit crop which has high demand in Ethiopia, but its production is constrained by lack of disease free planting material with conventional propagation methods. For shoot initiation, shoot tip explants were cultured on MS medium supplemented with 0.5, 1.0, 1.5 and 2.0 mg/L BAP. Similarly, MS medium supplemented with BAP at 1.0, 1.5, 2.0 mg/L in combination with IBA at 0.25 and 0.50 mg/L were used for shoot multiplication. Half- strength MS medium augmented with IBA at 1.0, 2.0, 3.0 and 4.0 mg/l were used for root induction. MS medium without PGRs were used as controls. Finally, hardening of the in vitro derived plantlets was carried out in green house both in the primary and secondary acclimatization stages. Results showed that the highest shoot initiation percent (93.40%), highest mean number of shoots per explant (4.67) and lesser day for shoot induction (11.00) were observed in explant cultured on MS + 1.0 mg/L BAP. With shoot multiplication, highest shooting percent (92.60%), maximum number of shoots (7.67) and highest shoot length (5.27 cm) were recorded on MS + 1.5 mg/L BAP + 0.5 mg/L IBA. The highest rooting percent (93.40%), maximum root number per shoot (7.67) and highest root length (11.00 cm) were found on a half strength MS medium + 2.0 mg/L IBA. The survival rate of plantlets were 96.00% in coco peat substrate in primary acclimatization and 97.92% in forest soil, sand and manure substrates mixed at 3:2:1 ratio in secondary acclimatization. Overall, the result showed that the PGRs type, concentrations and combinations used are effective for mass propagation of banana variety studied in this experiment.

This research was carried out to investigate the possibilities of removing the heat stress that may occur in Anatolian water buffaloes with a fogging system and to determine the cooling efficiency of the system. In this context, two 24-headed groups were formed among the water buffaloes that were considered to have the same genetic similarities, were born in the same period and have the same lactation number. One group was housed under controlled shelter conditions (Shelter-I), where the ambient temperature can be controlled, and the other group was housed in existing farmer-raising conditions (Shelter-II). The same feed rations were applied to both buffalo groups. The cooling efficiency of the fogging system established in Shelter-I was between 45.6% and 85.7% positive. Temperature-Humidity Index values changed between 19.9 and 23.1 in Shelter-I and 19.5 and 26.4 in Shelter-II according to the maximum average data. According to these values, the level of stress in Shelter-II has reached very serious levels and affected the milk yield of buffaloes negatively. The corrected 305-day lactation milk yields were calculated as 1965.4 kg in Shelter-I and 1757.1 kg in Shelter-II. The differences between all data obtained for Shelter-I and Shelter-II were found statistically significant.

Skeletal abnormalities in farmed fish are one of the main problems that negatively affect the production enterprises in terms of economic, biological and animal health. Fish with skeletal deformities in hatcheries are considered as non-economic individuals and are therefore detected and removed manually from the production tanks, which is a time consuming and laborious work for the facilities. Since the formation of abnormalities in the skeletal structure of the fish during the early growth period cause reduced swimming ability or speed that prevent fish to compete during feeding. Further, since deformed fish has no market value, even the share of a small amount of feed among deformed fish will reduce the feed conversion for the market targeted individuals within the culture tank that in terms may increase the production cost per fish. Therefore, in culture conditions it is important to remove the deformed fish from the tank environment by quickly determining those fellows at the early stage of growth. The present study evaluates the effects of water velocity on swimming behavior of juvenile seabass (Dicentrarchus labrax) and provides a solution for a rapid identification -and mechanical removal of deformed fish from the culture environment by using swimming speed slowdown -and behavioral differences as an indicator of deformation.
