Environmental destruction is dimensioned as one of the most important issues that the whole world is dealing with in the third millennium. For this reason, various policy instruments are developed and put into practice, both internationally and nationally. Although these policies cover all production and consumption areas, they also come to the forefront in terms of the agricultural sector due to their strategic importance. Environmental Agricultural Land Protection Program (ÇATAK), which came into effect in 2006, has been implemented in order to prevent environmental damage in the agricultural sector in Türkiye. In this framework, the production practices of grain producers benefiting from ÇATAK program supports in the Seyfe Lake region of Kırşehir province were examined in environmental terms. For this purpose, 100 producers were drawn into the sample and a survey study was conducted. The obtained data set was made into cross tables, interpreted and suggestions were made. The results were statistically supported by chi-square analysis. Accordingly, although it was determined that the producers did not implement practices that would cause environmental destruction intensively, it was observed that they needed to adopt the right methods from the right sources in the use of fertilizers and pesticides. In addition, it has been determined that the state does not have comprehensive knowledge about the agricultural policy instruments it has implemented. For this reason, it is considered important to implement training-extension activities frequently and dynamically.

Salmonellosis is a critical challenge in commercial poultry farming. This study aimed to calculate seroprevalence, identify Salmonella spp., and its pathological investigation from January to December 2019. One hundred fifty (150) serum samples and fifty (50) cloacal swabs from apparently ill and healthy birds were collected in this study. Seroprevalence was observed by serum plate agglutination (SPA) tests. The tentative diagnosis of salmonellosis was made based on history, clinical signs and bacteriological studies. Salmonella spp. was further confirmed using an automated microbiological method (VITEK®2). Post mortem examination was done in apparently sick birds, and gross and microscopic pathological lesions were investigated and recorded in a datasheet. The overall seroprevalence of salmonellosis was 42.67% in commercial chickens. Age wise prevalence of avian salmonellosis showed significantly highest infection rate in adult layers (≥ 45 days old) 65.31%, then 40.74%up to 45 days. In case of broiler, the prevalence rate in 0-10 days, 11-20 days, and 21-35 days were 13.63%, 44.12%, and 16.67%, respectively. Seasonal influence showed significantly highest proportionate prevalence of salmonellosis during summer 66.15%in comparison to winter 25.00% and rainy 24.44% seasons respectively. In bacteriological study, 12 samples were positive for Salmonellae among 50 cloacal samples. Out of 12 positive samples 5 samples were selected for the automated microbiology system VITEK® 2, and only two samples were confirmed as Salmonella gallinarum. Gross pathology of representative organs revealed bronze-colored enlarged liver, hemorrhages in the spleen and lungs, and hemorrhages in the ovary with stalk development. Microscopically, multifocal nodule formation and infiltration of inflammatory cells in the liver parenchyma and marked congestion with inflammatory cells in the spleen, hemorrhage and congestion in the lungs and intestine.

This study entitled was conducted in 3 places of Dolakha district namely Boach, Jiri and Bigu. The study was conducted during 20thjuly to 6th September 2017. The main aim of this study was to find out whether kiwi farming is improving household economy of people living there (i.e. Boach, Jiri and Bigu) using various tools such as questionnaire, discussion, direct observation and review of literature. A total of 60 households were randomly selected for the study. Both male and female were found to be involved in kiwi cultivation. About 60 percent and 40 percent of respondents were male and female respectively. 20 percent respondent were illiterate, 38 percent people have primary level education, 17 percent were people having secondary and S.L.C. level education respectively, similarly, the respondent completing Inter were 8 percent. Kiwi was the major cash crop in the study area and the widely used variety in the study site was Monti. Agriculture is the major occupation followed by Government job, Business and others. 47 percent were involved in agriculture, 30 percent were involved in government job, 13 percent have Business and 10 percent follow other jobs like (Teaching, Driving, Abroad). Among 60 respondents 50 percent were cultivating kiwi in 1-5 ropani of land and minimum was 12 percent who cultivated kiwi in above 15 ropani area. Training related to kiwi cultivation was also given to the respondent. 47 percent respondents were trained in kiwi cultivation and 53 percent were not trained about it. Training was organized and conducted by DADO and some other organization who were concerned about agriculture. Kiwi was mostly sold to nearest local market by the farmers themselves. Kiwi cultivation was also helping farmers in economic part. The study shows that there is an improvement of household economy and livelihood by kiwi farming.

The aim of this study is to investigate the effectiveness of biased estimation methods, principal component regression (PC) and ridge regression (RR) methods, according to unbiased the least squares (LS) method, against the multiple linearity problem (multicollinearity) encountered in regression methods. For this purpose to fit a model on account to predict body weight from some body measurements of 32 South Anatolian Red Kilis (SAR) cattle of different ages. R2, RMSE, MSE, and CV were used as the goodness of fit criteria for the performance of the models. According to these criteria respectively, 0.9970, 0.0224, 0.0005, 0.0099 for LS; 0.9970, 0.0224, 0.0005, 0.0099 for PC; and 0.9876, 0.0455, 0.0021, 0.0201 of k=0.02 for RR gave the best fit values. According to these results, LR and PC showed the best fit. But RR and PC techniques from biased prediction techniques provided more consistent, valid, stable, and theoretical expectations than LS technique, since LR did not provide the necessary assumptions.

The visual perception of landscapes is expressed as seeing the qualities of the landscape. This level of perception varies depending on the socio-cultural and economic structure of the people and the environment in which they live. The fact that the environment in which people live has a variable visual structure also constantly affects their landscape perception. Parks are one of the important urban landscape areas in cities. The existing structure of the parks located in the urban landscape areas affects the visual perception value of these areas on the users. The aim of the research is to evaluate the visual landscape quality value of the parks in the city of Serik in the direction of user opinions. In this context, the photographs of the selected parks within the boundaries of the research area were taken from certain points. The questionnaire form prepared with these photographs was applied to the park users on a voluntary basis. The data obtained from the questionnaire forms were digitized and analyzed. Within the scope of the analysis, the data belonging to the socio-demographic structure of the participants and the answers they gave to the propositions about the parks were determined by descriptive analysis (frequencies and descriptives). Whether there was a statistically significant difference between the sociodemographic structure of the participants and their answers to the propositions was analyzed with parametric tests (independent sample t-test and one-way analysis of variance). At the same time, the relationship between the visual landscape quality assessment criteria of the parks was examined by Pearson Correlation Analysis. The results of the analysis show that the features of the parks due to their planning, design and maintenance affect the visual landscape quality values. In this direction, suggestions have been developed to increase the visual landscape quality value of the parks.

It is one of the biggest city parks of Ankara, which people can easily reach in daily use, walking, jogging, sitting, picnicking, playing etc. Göksu Park, which provides opportunities for activities such as, is built on the old Susuz pond in Eryaman. The park was opened in 2003. In this study, a 3-stage method was applied to determine and evaluate the area adequacy of the park. In the first stage, the first picture selection was made with the team of landscape architects in the park, using the nominal group technique, among the photographs taken in the area, obtained from the municipality and received the most likes from social media accounts with many followers. In the second stage, the criteria for the evaluation of field adequacy with the Delphi technique were determined by consulting the faculty members in the Department of Landscape Architecture, Faculty of Agriculture, Ankara University, who were selected as experts on the subject. Then, using the observation and comparison tables, the survey questions were prepared and after the application of the survey to the visitor group and park staff, as the third step, the survey data was based on whether the difference between the observed frequencies (OF) and expected frequencies (EF) was statistically significant with the help of SPSS 25 statistical program. Chi-square independence analysis, which is a test, and linear regression analysis were performed. By counting the frequencies, the relevant photographs will be examined and the relationship between density and field adequacy has been interpreted. With this study, it will contribute to the plans and designs of new projects so that the green areas and parks that people need due to the increasing population and urbanization can be used adequately in the future.

This study aimed to investigate the body weight and some body measurements in Central Anatolian Merino sheep regarding ages and to carry out a comparative analysis between them. The study included a total of 60 animals aged 2, 3 and 4 years. The sheep were fed daily with hay, vetch, alfalfa and limited amount of concentrated feed (400 g head-1) until the pasture period, and pasture grass and mixed grass-clover hay during the pasture period. The live weights of the sheep of different ages in the farms were measured with a digital scale, and some body size were measured using a measuring tape and a measuring stick. When the live weight and chest circumference values of the 4-year-old sheep were compared with the data obtained in the other age groups (2 and 3 years old), and it was statistically significant, chest width and rump height values were found to be similar to those in the 3-age group. There were significant correlations between live weight and chest circumference, between withers height and rump height and significant correlations between live weight and chest width, body length with rump height, chest width with chest depth. In addition, significant correlations were found between live weight and chest depth, and between withers height, body length, and chest depth. Present findings revealed that the Central Anatolian Merino sheep can be beneficial in the development of meat-type sheep breeding.

In this study, the effect of foliar L-Histidine and Methinonin amino acid applications on grain cadmium (Cd) and zinc (Zn) uptake on durum wheat grown in soil contaminated with Cd was investigated. The research was carried out according to the randomized blocks design as a pot experiment in greenhouse conditions. In the experiment, Cd doses were applied as control (0 mg Cd kg-1) and (3 mg Cd kg-1). L-Histidine and Methionine amino acids were applied 7 times from the leaf after the start of flag leaf formation in wheat at 0.5 mM doses and harvested after the grain maturity was completed. According to the results obtained, the wheat grain dry matter yield in 3 mg Cd kg-1 polluted soil was 44.5 mg grain-1 in the control, while the dry matter weight was increased with the application of L-Histidine and Methionine from the leaves being 48 and 50 mg grain-1, respectively. It was determined that there were differences in grain Cd and Zn concentrations with the application of amino acids from the leaves at the dose of 3 mg kg-1 cadmium. When the grain Cd and Zn intakes were compared with the control, it was found that the grain Cd concentration decreased, and the Zn concentration increased as a result of the application of amino acids. The high amount of Cd in wheat can make it to the human body through the food chain and is known to cause serious health problems after a certain amount of accumulation. As a result of this study, it is seen that L-Histidine and Methionine are effective in reducing Cd in the grain, and these amino acids probably form a complex with Cd, resulting in less transport.

This study was designed to investigate the therapeutic effects of Vitis vinifera L. seed extract (5 ppm and 10 ppm) on gill and liver tissues histopathology of carp (Cyprinus carpio L. 1758) exposed to cadmium chloride (CdCl2=Cd) (20 ppb) acute and subchronic period. A total of 140 fish in 14 groups were used in the experiment. The experiment was designed as in two different periods (acute and chronic) and 7 different dose groups (control, vehicle, V. vinifera seed extract 5 ppm, V. vinifera seed extract 10 ppm, Cd 20 ppb, V. vinifera seed extract 5ppm + Cd 20 ppb and V. vinifera seed extract 10 ppm + Cd 20 ppb). At the end of the experiment, the gill and liver tissues dissected from the fish were fixed, dehydrated, cleared, and paraffin impregnated. Appropriately sized blocks were prepared from the tissues, sections of 5-7 µm thickness were taken and covered by staining with hematoxylin-eosin. Stained preparations were examined under a light microscope and photographed. It was determined that all dose groups in the acute period and control groups were not different histopathological. It was determined that the histopathological damage caused by the cadmium group in the subchronic period and tissue damage were reduced in the dose groups with cadmium added with V. vinifera seed extract. As a result of the study, it was concluded that V. vinifera seed extract could have a therapeutic effect on the gill and liver tissues of carp exposed to cadmium.

In this research; the current situation and problems of the cold storages in the province of Van have been studied. In this direction, 21 cold storages registered in Directorate of Van Provincial Agriculture and Forestry were visited and on-site investigations were made. The findings obtained as a result of the surveys made with their owners by considering the features of the cold storages such as the structural and mechanization status, the type of stored product have been effective in identifying problems and suggesting solutions. It is used for white meat and eggs 29% of cold storages, 29% for milk and dairy products, 29% for red meat and 13% for fruit and vegetable storage. In addition, there are 17 fruit and vegetable warehouses, 13 of which are unused, that are not registered in Directorate of Van Provincial Agriculture and Forestry, and these were excluded from the research because they were not registered. The most important problems in warehouses were experienced during the Covid- 19 pandemic process. Lack of the technical capacity, machinery and equipment, qualified personnel, the marketing problems, maintenance and repair, rent, electricity and water expenses are the main ones. Improvement of its structural properties, modern mechanization device, establishment of unions that will enable warehouse owners to act together, eliminating the lack of qualified personnel with Van Yuzuncu Yil University, one of the most important educational institutions in the region and measures to increase export potential will play an important role in solving the problems.
