Abstract :
Agricultural production can be improved by some factors such as right amount of chemical applications, use of high quality production materials, utilization of suitable machinery, increasing of cultivated and irrigated land and adaptation of water saving irrigation technologies. In this study, production performance in agriculture of Turkey during the periods 1981-2008 was researched. Real agricultural gross domestic product (RTGSYİH) as a representative of total agricultural production was used. To express this, Logarithmic regression model was applied. In model chemical fertilizers use as crop nutrient element, tractors number and milk yield per animal were used as explanatory variables. The variables explained 92,6% variation on RTGSYİH. In result of model, production elasticity of chemical fertilizers as plant nutrients, milk yield per cow and tractor number were calculated as 7,8%, 9,4%, 28,2, respectively.
