In this context, a face-to-face survey was conducted with the owners or authorized persons of the small, medium and large size farms and the data collected from the farms about technical, sanitation-hygiene and health protection were comparatively presented. According to the findings obtained from the study, manure and wastes produced in 24% of farms were seen randomly throwing into the environment, and the differences observed between farms depending on the farm size were found significant (P<0.05). These farms can become a potential source of environmental and odor pollution. In addition, it was determined that disinfection was not applied to a large extent (97.30%) as a preventive measure at farm and shelter entrances (P>0.05). At the end of the study, it has been concluded that the typology and biosafety practices could be an important support for future strategic programs against disease and other factors which affects the production of the Niğde region.","PeriodicalId":23389,"journal":{"name":"Turkish Journal of Agriculture: Food Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135463107","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}

Purposive and two stage sampling technique was used to select 384 sampled households. The study used logistic regression model to identify the determinants of adoption decision of modern beehive technology while propensity score matching to evaluate the impact of modern beehive technology adoption on household income. The result of logistic regression model shows that age of household head, family size, households experience in beekeeping, frequency of extension contact, access to credit services, access to training and access to beehive demonstration site visit had positive and significant effect on household adoption decision of modern beehive technology. The result of propensity score matching indicates that the adopters of improved beehive technology were earned Birr 2690.383 than non-adopter. The difference in household income between the two groups shows that there is considerable room for improvement of household income through increasing the number of adopter of improved beehives technology in the study area.

However, genetic structure is the most critical criterion for determining a species's potential to adapt to changing environmental conditions. Monitoring gas exchange parameters in plants is the simplest way to monitor physiological changes in plants under changing environmental factors. Among species, the Anatolian chestnut (Castanea sativa) is native and economically important tree species (fruit and wood production). It is naturally distributed from the north side of Turkey, Marmara, and Western Anatolia. However, the Anatolian chestnut is one of the most affected tree species by global climate change. In this study, numerous Anatolian chestnut populations (3 years old) were used to determine leaf gas exchange parameters at the end of the growing season in Düzce. Stomatal conductance (gs), transpiration rate (E), net photosynthetic rate (Anet), and other parameters were measured. As a result, the leaf gas exchange parameters of chestnut populations changed significantly based on the populations. Marigoule population seedlings had 2-fold Anet values compared to the Ibradı population. Regarding gs, the differences between populations (Erfelek and Ibradı) changed approximately 2.5 folds and the differences (Erfelek and Ibradı) increased more than 3 folds in terms of E values. It can be said that Marigoule and Erfelek populations can adapt more to Düzce climate conditions than other populations. In contrast, Ibradi population seedlings have a low adaptation mechanism in terms of gas exchange traits.","PeriodicalId":23389,"journal":{"name":"Turkish Journal of Agriculture: Food Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135462967","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}

The sample of the study consisted of 100 wheat producers in the Mucur district of Kırşehir province. The obtained data were interpreted by converting them into tables, cross-tabulations, and graphs. The data in the cross tables were statistically interpreted using Chi-square analysis. It can be said that producers are not satisfied with TGBs’ purchasing practices for some reasons. The most important reason for this is that quality-based purchasing practices have an extremely negative impact on prices. It was determined that they were not satisfied, and this resulted in high price reductions in quality-based purchasing, and as a result, there was distrust in analysis practices. Quality-based purchasing policy is a method that allows wheat quality characteristics to be determined with various devices in a short time. This method, which is decisive in quality classification and product pricing scale, must be explained correctly to producers. Otherwise, the producer ’s trust in the TGB may gradually decrease. This can be achieved through initiatives taken by the institution or through various publications and training activities. One of the most important results of this study is that TGBs and decision-makers are more sensitive to local producers. For decision-makers to maintain their influence on the producer, they must carefully examine the details of the processes with an inductive approach, starting from the bottom up. This situation is considered critical in terms of food security.","PeriodicalId":23389,"journal":{"name":"Turkish Journal of Agriculture: Food Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135462629","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}

By using these isolates, pectinase group enzymes; studies on pectin lyase and polygalacturonase production were performed in the batch system and under non-sterile culture conditions. 5 isolates denoting polygalacturonase activity were coded as: T1, T2, T3, T4, T5 and the best polygalacturonase activity among these isolates was determined as 354.4 U/L in T4 isolate. Thus, optimization analyses continued by the use of this isolate. Initial apricot pulp concentration, temperature, pH and incubation period were tested as optimization parameters. The effects on enzyme activities were investigated by changing the initial apricot pulp concentration in the range of 5-100 (g/L), and in this regard, polygalacturonase activity was determined as 397.4 U/L at 50 g/L. In addition, the pH parameter was analyzed in each unit between pH = 3 – 8, and the temperature was tested by increasing 5 units in the range of 5-25°C. Consequently, the maximum polygalacturonase activity was determined as 405.7 U/L at pH 5 and 406.3 U/L at 15°C. Besides, the effect of the incubation period was studied within 1-5 days and the maximum polygalacturonase activity was determined as 429.0 U/L on the 4th day (after 96 hours). As a result, the above-mentioned T4 isolate, with which the optimization studies were conducted, was identified as Sarocladium strictum (Top ekinküfü) T4 by molecular methods.","PeriodicalId":23389,"journal":{"name":"Turkish Journal of Agriculture: Food Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135463099","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}
