Textural, color (L*, a* and b*) and sensory attributes (appearance, color, texture, taste and odor) were also assessed in samples with and without biosynthesized xanthan gum. The textural properties and water-holding capacity of the yoghurt were significantly (p0.05) between the samples at the end of storage, except for the sample with 0.2% xanthan gum. The addition of the highest concentration of xanthan gum increased the a* and b* values while decreasing the L* value (p 0.05) between BX0.1% and BX0.2%, the samples with the lowest L* value. The addition of biosynthesized xanthan had no significant effect (p> 0.05) on the total solid, protein and ash content of yoğurt. Besides, the biosynthesized xanthan gum had no negative impacts on the sensory characteristics of yoghurt, except for the appearance. The findings indicated that biosynthesized xanthan may be a desirable additive since it enhances the physical characteristics of yoghurt without affecting its nutritional value or sensory properties.","PeriodicalId":387927,"journal":{"name":"Tekirdağ Ziraat Fakültesi Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126245221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Turkey is partly located within this basin having a rich source of biodiversity. Olive growing in Turkey is carried out in the Aegean, Marmara, Mediterranean, Southeastern Anatolia and Black Sea Regions. Climatic factors determine the cultivation limits of olive which is not very selective in terms of soil demand. In regions where olives are grown, the Mediterranean climate prevails. Winters are warm and rainy in the region, while summers are hot and dry. On the other hand, severe cold damage in some years can cause significant damage especially in the inner parts of Aegean, Marmara and Black Sea Regions. As a matter of fact, it is known that 31.8% of olive plantations in Turkey are exposed to occasional frost damage. This situation has revealed the necessity of determining the varieties with high frost tolerance and determining the suitable varieties for the regions where cold damage may occur. In the study, 40 registered olive cultivars in “Kemalpaşa Olive Germplasm Bank\" in Bornova Olive Research Institute, in İzmir were screened in terms of frost tolerance. To evaluate the frost tolerance (LT50) of cultivars, as estimated by ion leakage (electrical conductivity), leaf samples taken in six different periods over two years were exposed to temperatures at +4 °C (control), -2 °C, -5°C, -8 °C, -11°C, -14 °C, -17 °C and -20 °C. In conclusion; it has been determined that frost tolerance of olive varieties revealed significant variability both genetically and seasonally. Butko, Memeli, Otur, Gemlik, Sinop No 5, Yün Çelebi, Kara Yaprak, Satı and Sarı Ulak were determined as cultivars that were more tolerant of frost. Sinop No 1, Marantelli, Ayvalık, Görvele, Çakır, Samsun Tuzlamalık, Erkence, Saurani, Eşek Zeytini (Tekirdağ), Kan Çelebi, İzmir Sofralık, Çilli, Samsun Yağlık, Domat, Eşek Zeytini (Ödemiş), Saçaklı Otur, Sinop No 4, Memecik, Nizip Yağlık, Tekirdağ Çizmelik and Patos were found to be moderately tolerant cultivars while Edincik, Sinop No 6, Çekişte, Mavi, Kiraz, Kilis Yağlık, Çelebi (İznik), Trabzon Yağlık, Uslu and Girit olive cultivars were grouped as cultivars having low tolerance to frost. In addition, data showed that cold acclimation in the olive is quite important, and exposure to low temperatures for a certain period of time has significantly increased the frost tolerance. However, this condition was not stable and could rapidly become reversed when temperature reached to the point at which adapdation did not ensure.","PeriodicalId":387927,"journal":{"name":"Tekirdağ Ziraat Fakültesi Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127832767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, another aim of the study is to provide a widespread consumption potential through ice cream to propolis, which cannot be consumed raw and whose benefits and functional properties are unknown to most consumers. A mixture consisting of a total of 6 sample groups containing 0.0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% propolis powder was prepared for the ice cream mix. Ice cream samples were prepared from these ice cream mixes. Different analyses were executed for propolis, ice cream mix and ice cream samples. While only antioxidant analysis was executed for propolis samples, Dry matter, pH, titration acidity analyzes were executed in ice cream mix samples. Volume increase index, texture analysis, melting rate, antioxidant activity and sensory analyzes in propolis added ice cream samples were carried out on different days during 2 months of storage. According to the findings, while the volume increase of the ice cream samples was not affected by the storage time, the difference between the propolis concentrations was found. It was observed that the first dripping times increased with storage, while the melting rate of the ice cream decreased. There was no significant change in the meltıng rate and first drip times depending on the propolis concentrations. The texture properties of ice cream samples have changed with the addition of propolis. The hardness and stickiness values of ice cream samples changed depending on the storage time. The addition of propolis significantly increased the antioxidant activity. Antioxidant activity was changed with the addition of propolis. The phenolic content and of ice cream did not change with storage, but FRAP value decreased slightly after 60 days of storage. Storage time had a limited effect on the physicochemical and sensory properties of ice cream. Although the addition of propolis negatively affected the physical and sensory properties of ice cream, it contributed significantly to the antioxidant activity even at the lowest concentrations. With this study, the potential of propolis-added ice cream as a functional new food for consumers of all ages has been demonstrated. In line with these results, new studies should be conducted by trying different propolis extracts and different concentrations, by revealing the functionality of propolis and adding it to new other foods.","PeriodicalId":387927,"journal":{"name":"Tekirdağ Ziraat Fakültesi Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121631276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to assess erosion and sedimentation in the Krueng Jreu sub-basin in the province of Aceh, Indonesia, using the Gavrilović method. This research was carried out by analyzing secondary data for the last ten years, from 2012 to 2021. Data include geology, slope, land use, and river channel networks. The observed parameters include the coefficient of intensity of erosion, temperature coefficient, and sedimentation coefficient, which are used to analyze the erosion volume, spatial sediment rate, and total sediment rate in the Krueng Jreu sub-basin area. The results of calculations using the Gavrilović method show that four main parameters of the biophysical characteristics of the sub-basin, including (1) sensitivity of soil and local geological conditions to erosion, (2) land use, (3) erosion type, and (4) slope of land, have been shown to affect the occurrence of erosion and annual sediment rates. Geological conditions and land use provide a high level of sensitivity to the results of the coefficient of intensity of erosion. Temperature and rainfall are directly proportional to the annual erosion volume and the spatial sediment rate. The lowest yearly erosion volume and spatial sediment rate in 2019 were 64965.41 m3km-2year-1 and 58206.18 m3km-2year-1. Meanwhile, the highest annual erosion volume and spatial sediment rate will occur in 2021, 101500.71 m3km-2year-1 and 90940.21 m3km-2year-1. Fluctuations in the annual volume of erosion are caused by rainfall, affecting the spatial sediment rate and the total sediment rate.","PeriodicalId":387927,"journal":{"name":"Tekirdağ Ziraat Fakültesi Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134328975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various plans, programs and policies are being developed for the sustainability of production and solving the problems of those living in rural areas. In recent years, it has been given importance to support development and entrepreneurship in agriculture in Türkiye in order to solve the existing problems. For this purpose, the Young Farmer Project was put into effect with the decision of the Council of Ministers in 2016. With this project, it is aimed to ensure that young farmers stay in the agricultural sector by providing the support they need, and to prevent migration from rural to urban by encouraging their agricultural production and activities. In this research, the application process of the farmers who received support between 2016 and 2017 in Tekirdağ province with the Young Farmer Project, how they carried out the project, what kind of difficulties they faced while carrying out, how they continued it, and where they could carry it was determined. A survey was conducted with 106 young farmers who received support within the scope of the research. 54% of the young farmers participating in the research are woman farmers. The fact that male farmers have existing businesses registered on them that they work in other paid jobs besides farming, positive discrimination against women within the scope of the project has contributed to the increase in the number of female young farmer applicants and winners. 82.1% of the young farmers involved in the project also reside in the rural area before the project, and 13.2% live both in the city center and in the rural areas. The rate of those who started living in rural areas after receiving project support is 4.7%. It has been determined that young farmers who own livestock enterprises do not have an increase in their income levels, and they have difficulty in meeting their borrowing and operating input costs. Young people who receive support within the scope of the Young Farmer Project express the opinion that the project will not encourage agriculture and animal husbandry. For women farmers, the most important contribution of the project is that they have owned businesses for the first time, and for male farmers, they have further expanded their existing businesses.","PeriodicalId":387927,"journal":{"name":"Tekirdağ Ziraat Fakültesi Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129862090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological dinitrogen fixation (N2) is a very important natural process in world agriculture. Rhizobia is a common name for a certain Gram-negative group of Alphaproteobacteria and Betaproteobacteria that can form nodules on the root and fix nitrogen in symbiosis with legumes as their host plants. Azotobacter spp. is a free-living microorganism that has the ability to fix atmospheric nitrogen into the soil. Field trials were carried out of Eskişehir Osmangazi University Field Crops Department experiment areas during the production season of 2017 and 2019. The study was evaluated the effects on morphological and phenologocial characters of two N doses (0 and 25 kg ha-1 N), four bacteria inoculations (control, Rhizobia, Azotobacter, Rhizobia + Azotobacter) on chickpea cultivars (Azkan, Akca, Cakir, Isik). Experiment arranged in split split plot experimental design with three replications. Nitrogen application positively affected number of days to emergence, number of branches, branch diameter and grain yield. Phenological and morphological properties affected by climate conditions. The high temperature caused the number of days to emergence, number of days to flowering and number of days to maturity to be earlier in the second year. Plant height, first pod height and grain yield were higher first year than second year due to high precipitation. While the response of the cultivars was different in terms of phenological properties, Azkan cultivar gave the best results in terms of morphological properties. Rhizobia + Azotobacter inoculation gave the best results in terms of phenological and morphological characteristics except for number of days to maturity. Rhizobia + Azotobacter inoculation can lead to additional income generation of the farming community in Turkey.
