Osman Uysal | Duygu Birol
This study aims to determine the characteristics of young farmers and their businesses that benefit from and cannot benefit from young farmer support in the Mediterranean Region and determine the factors that affect the benefit of young farmer project support. In 2016, a survey was conducted with all 160 producers who benefited from young farmer support, and a survey was conducted with 56 producers who applied for young farmer project support but could not benefit from it to make comparisons between groups. The tendency of farmers to benefit from the young farmer support project was determined using artificial neural networks and logistic regression analysis. It was determined that the majority of the producers who received support only made animal production and mixed production (livetock production and vegetable production), while the majority of the producers who did not receive support made only plant production. With both analysis methods, it was determined that the most critical variables that affect the benefit of young farmer project support are the type of activity, the share of non-agricultural income in total income, the number of farmers in the family, the education period, the status of having non-agricultural income and family size. The total correct classification rate was found to be 87.04% in the logistic regression analysis and 91.20% in the artificial neural network analysis, and it was seen that the classification percentages obtained by both methods were quite close to each other.

Yaşar Erdoğan | Metin Turan
The types and densities of honeyed plants vary depending on the altitude. This causes the amount and Physicochemical structure of honey produced in apiaries of different altitudes to change. In this study, honey harvest from the honeybee colonies placed at different altitudes in the same geographical region was carried out in the first week of September. Standard laboratory methods were used to determine some physicochemical properties of the honey samples. Some of the minimum and maximum average values obtained as a result of the analysis of honey samples; moisture 14.70% and 18.60%, free acidity 20.50 meq/kg and 25.30 meq/kg, pH 3.20 and 4.30, EC 0.22 and 0.44 mS/cm, fructose 32% to 45%, glucose 0.10% to 0.18%, sucrose from 0.66% 1.80%, maltose ranged from 0.66% to 1.80%. Also, HMF ranged from 1.80 mg/kg to 3.50 mg/kg, proline 530.00 mg/kg and 710.00 mg/kg, Density from 1.44 g/cm3 to 1.49 g/cm3, Invertase 20.30 U/kg-28.50 U/kg, Diastase activity 13.23-19.07 and Total phenolic content ranged from 76.00-94.00 g. It has been determined that the physicochemical structures of honey produced at different heights are statistically different from each other. This study aims to determine the effect of altitude difference on the quantity and physicochemical structure of honey.

Cihan Çakmakçı
The objective of this study was to compare predictive performances of four machine learning (ML) models: Support Vector Machines with Radial Basis Function Kernel (SVMR), Classification and Regression Trees (CART), Random Forest (RF) and Model Average Neural Networks (MANN) to predict live weight from morphological measurements of Norduz sheep (n=93). Seven morphological measurements; chest girth (CG), chest width (CW), chest depth (CD), height at withers (HW), body length (BL), heigth at rump (HR) and rump width (RW) were used to predict live weigth (LW) of Norduz sheep. All morphological measurements were positively correlated to LW. Live weight had the highest correlation with CG and the lowest correlation with HR. Initially, highly correlated predictors were removed from the data set. The remaining predictors were then subjected to variable selection procedures using the Boruta algorithm. The results of Boruta confirmed the importance of the four predictors HW, BL, CW, and CD. However, HR confirmed to be unimportant was excluded from the dataset. The ML models were trained on selected predictors. The results showed that the prediction performance validated using the test dataset indicated that RF had the lowest values of Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and Mean Absolute Percent Error (MAPE). The permutation-based variable importance scores indicate that CW and CD were the most important variables in predicting LW. The actual LW had the highest significant positive correlations with the values predicted by SVMR and RF, and followed by ANN and CART models respectively. There were no differences between the means of actual and predicted LWs by machine learning models. The fact that the models generalized well on the testing data sets indicates that machine learning algorithms have valid predictive patterns and are effective methods in LW weight of Norduz sheep. Considering runtime of the models, although the CART model had the lowest computational cost, it had the worst performance. The MANN algorithm, on the other hand, required a longer runtime to process the same dataset.

Abdulkerim Diler | Mete Yanar | Veysel Fatih Özdemir | Recep Aydın | Rıdvan Koçyiğit | Ahmet Yılmaz
This study was carried out in the central county of Ağrı Province in order to reveal the cattle feeding habits of cattle breeders. For this purpose, data were obtained by conducting a face-to-face survey with 400 dairy cattle owners of the enterprises in the county. According to the results obtained from this study, it was determined that 91.5% of the breeders produced their forage crops. It was also found out that barley, alfalfa, and sainfoin were the most produced plants in these enterprises. However, the production of the corn silage, which is an important source of roughage for dairy cattle, was performed at a very low level (1.2%). Dry hay (93.5%) took first place among the roughage sources used in these enterprises, and it was followed by alfalfa hay (61.5%) and wheat-barley straw (28.0%). Corn silage was used at a low level (7.8%) in the cattle enterprises. It was determined that cattle breeders in the central county of Ağrı province were deficient in terms of some information about cattle feeding practices. It was also demonstrated that it was necessary to increase the usage and production of corn silage as forage crops and to implement rational animal feeding practices in place of the old traditional animal feeding habits. Therefore, cattle breeders in the central county of Ağrı province should be involved in technical training programs about the cattle feeding and forage planting. As result of the courses given to the cattle breeders, their technical information about cattle nutrition and preparation of ration would be updated. For this purpose, it is also recommended that agricultural extension service should be boosted to increase the education level and awareness of the cattle breeders in the rural areas.

This study was carried out in 2019 to determine the effects of methyl jasmonate (MJ), gibberellic acid (GA3) and naphthalene acetic acid (NAA) applications on fruit yield and essential oil content in anise (Pimpinella anisum L.). Different concentrations of MJ (0, 0.1, 0.5 and 1 mM), GA3 (0, 50, 100 and 150 ppm) and NAA (0, 25, 50 and 100 ppm) were pulverized to the plant during the beginning of the flowering. Phytohormone applications had a statistically significant effect on the parameters examined in the study, and the effects of the applications generally varied depending on the application doses. While GA3 and NAA applications significantly increased the fruit yield and essential oil content compared to the control, high-dose MJ applications generally had a negative effect on all parameters except that the thousand-grain weight. The highest fruit yield was obtained from 100 and 150 ppm GA3 and 25 and 50 ppm NAA applications, while 1 mM MJ applications significantly reduced fruit yield compared to the control. Depending on the applications, the fruit essential oil content varied between 1.94%-2.69% and the essential oil yield varied between 1.42-3.18 L/da. While the highest essential oil yields were obtained from 100 ppm GA3 and 50 ppm NAA applications, 1 mM MJ applications caused a significant decrease in essential oil yield compared to the control.

In this study, the effects of hazelnut husk (HH), peat (P) and growing medium consisting hazelnut husk + peat (HH:P) mixture on the growth of lettuce and some nutrient contents were investigated. In the experiment, vermicompost (VC) was added to 3 different media at a rate of 0-10-20-30-40-50% by volume. The research was carried out according to the randomized plot design with 3 replications. According to the research results, the fresh and dry weight of the lettuce plant, the number of leaves and the length of the leaves showed significant increases with vermicompost added to the media compared to the control, and it was determined that 40% vermicompost application to hazelnut husk and hazelnut husk+peat mixture was effective. It was determined that the root fresh and dry weight of the plant increased regularly with vermicompost applications and when the root development was evaluated in general, 50% vermicompost application on hazelnut husk+peat mixture and hazelnut husk were effective. Similarly, vermicompost added to the media regularly increased the total N, P, K, Mn and Zn contents of the lettuce plant. Considering the effect of the medias, the macro element contents of the plant were found to be higher in hazelnut husk and hazelnut husk+peat medium, Mn content in peat and Zn content in the mixture. When the effects on the growth parameters and leaf nutrient contents of the lettuce plant were evaluated, it was concluded that the addition of 40-50% vermicompost to hazelnut husk and hazelnut husk+peat media could be used as a seedling growing medium.
