    Animal Manure as One of the Main Biogas Production Resources: Case of Turkey
    (Medwell Online, 2009) Tatlidil, F. Fusun; Bayramoglu, Zeki; Akturk, Duygu
    Generating power from renewable energy resources has become increasingly important in the world. One of the main renewable energy resources is biogas. People have been using biogas for over 200 years. First of all, biogas is a resource of energy that is environment-friendly and manure. In many parts of the world, biogas is used to heat and light homes, cook and as manure in the fields and even as fuel for buses. It is collected from large-scale resources such as landfills and barns and through small domestic or community systems in many villages. Biogas contains agricultural waste such as manure and plant waste. In order to protect environment, the usage of biogas should be increased. There are several biogas plants in Turkey. The main aim of this study is to determine the potential of biogas production produced by livestock and poultry waste in Turkey. According to livestock and poultry population, agricultural sector has an important resource for biogas production. Biogas potential will be calculated in compliance with type of livestock and poultry.

    Development Trends of Aquaculture in the World
    (Medwell Online, 2009) Tatlidil, F. Fusun; Akturk, Duygu; Bayramoglu, Zeki; Fidan, Halil
    In this study, development trends corresponding to the period 1980-2003 of the countries that have a voice in world aquaculture production are analyzed, taking into consideration the variables like their production, consumption, import and export. In the study, panel data set has been used in the analysis of the factors affecting fish import and export of the selected countries. In panel data set there are 12 horizontal cross-section data and 24 time series. The study includes the explanation of import and export of 12 countries performing the highest fish production in the world. In order to explain import and export, two models have been established and Chow test has been applied for both models. According to the results of the analysis, while import increases export at a rate of 17.04%, export increases import at a rate of 7.06%. While, relative increase in production decreases import at a rate of 5.66%, it increases export at a rate of 4.96%. Production affects import and export at the same rate but in opposite directions. The signs of consumption coefficient are harmonious with the expectations and while, its relative increase decreases export at a rate of 5.57%, it increases import at a rate of 5.99%. Income affects import positively and its relative increase increases import at a rate of 152%. Decrease in the value of country currencies against dollar decreases export at a rate of 0.25% while its increase increases import at a rate of 7.08%.

    Effects of land cultivation systems on wheat production costs
    (Wfl Publ, 2010) Akturk, Duygu; Bayramoglu, Zeki; Tatlidil, F. Fuesun; Savran, Ferhan
    In this study, the effects of the various land cultivation systems on production costs, efficiency and resource usage have been compared for conventional and protective wheat production. The study has been conducted in the Turkish region Tekirdag with intensive agricultural practices encompassing 80 enterprises having 120 ha or more of wheat. Over 30 of the enterprises practiced protective agricultural methods and used direct planting machines. The other 50 enterprises performed their wheat production activities by conventional systems. The production costs has been estimated to 0.26 US $/kg for the enterprises using direct plantation machines and to 0.31 US $/kg for the enterprises using conventional systems. The proportion for the production costs of the soil preparation and plantation costs arc higher than that of the enterprises making production by conventional systems. Besides, the effects of rational usage of the resources for wheat production on its cost and efficiency have been analysed. A positive (0.236) correlation between the efficient resource usage and efficiency of the enterprises making production by soil protection system and conventional system has been determined. Additionally, a negative (-0.579) correlation between efficiency and cost of these enterprises has been found.

    The Factors Affecting Milk Production and Milk Production Cost: Canakkale Case - Biga
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2010) Akturk, Duygu; Bayramoglu, Zeki; Savran, Ferhan; Tatlidil, F. Fusun
    In this study, the relationship between milk production and the factors used in milk production have been analyzed and the cost of milk production has been calculated. The data used for this study has been acquired from 94 dairy cattle breeder enterprises by the face to face survey method. It has been determined that the forage and concentrated feed costs compose 57% of the total production costs and 71% of the variable costs. It has been also determined that the dairy cattle breeding production division of the costs belong to 20.99% of productive stock value (PSA), 76.31% of milk production and 2.7% of manure production and 1 kg milk cost has been calculated as 0.29$. Additionally, according to the path analysis, it has been found out that the 61.49% variation resulting from the milk production can be explained with the changes resulting in the use of forage and concentrated feed. Through the path analysis, the direct and indirect effects of the feed materials used on the milk production have been analyzed. As a result, it has been found that silage maize (20%) and barley(14%) have the biggest effect on the milk yield.
