Abstract
Although Turkey's agricultural sector is important in terms of national economy, it faces some important structural problems such as decrease in human capital in the agricultural sector. In order to solve these problems, within the "National Agricultural Project", a policy instrument named "Support for Young Farmers Projects" (YFPS) was added to the support in 2016. The aim of this study was to evaluate the criteria used in the selection of the beneficiaries of young farmers' support within the scope of YFPS in Turkey. A survey was prepared to determine what features young farmers benefiting from project support have and the extent to which the selection criteria served the purposes of the support program. The survey was conducted in the TR 71 Region, which is at the center of Turkey, in June-August, 2017. A total of 248 young farmers (139 supported, and 109 non-selected farmers for support) were interviewed. The methodology used in this study was the Categorical Regression. The results showed that the applicants who benefited more from YFPS were in the following order: Female> married> those aged 18-30> people from rural areas with a population of 1,000 or less> those with education in agricultural production> the disabled / martyr’s relatives / ghazi, and those from enterprises with an annual income of TL 10,000 or less. YFPS has breathed new life into agriculture by encouraging youths in rural areas, but this support has to be aimed at creating economically sustainable and viable enterprises.

Abstract
Three trapezoidal piles of the mixtures consisting of rose oil processing solid wastes, separated dairy and poultry manure, and straw as bulking agents were composted to determine the effects of aeration pattern employing forced aeration on various physical and chemical properties and energy consumption by aeration. Temperature feedback control of aeration fans was performed with Rutgers strategies in the positive mode. Aeration patterns with on/off cycles (minute/minute) of 5/30, 7.5/30, and 12.5/30 were performed for Pile-1, Pile-2, and Pile 3, respectively. The control group was set to 5/30 (on/off time) and the experimental groups were set to 7.5/30 and 12.5/30 (on/off time). The results showed that although composting performance parameters of temperature and O2 as a function of time showed some differences, the similar end-product quality in terms of pH, EC contents and total phosphorus was achieved. The highest energy consumed by fans per Organic Matter Loss (OML, %) of composting (1.044 kWh/OML) was obtained when the fan on/off cycles of 5/30 was applied. When the fan on-time increased to 12.5 min, the energy consumed by the fan was reduced by 12.55% (0.913 kWh/OML). It was concluded that operating the composting process at the higher fan on-time (Pile-3) within acceptable limits appears to be economically convenient in conjunction with energy consumption by aeration fans.
