    Effects of Land Cultivation Systems on Wheat Production Costs
    (Wfl Publ, 2010) Aktürk, Duygu; Bayramoğlu, Zeki; Tatlıdil, F. Füsun; 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: Çanakkale case - Biga
    (2010) Aktürk, Duygu; Bayramoğlu, Zeki; Savran, Ferhan; Tatlıdil, F. Füsun
    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.
