THE DETERMINATION WITH GEOGRAPHIC INFORMATION SYSTEMS (GIS) MAPPING OF THE ENERGY USE EFFICIENCY OF POTATO PRODUCTION AREAS IN TURKEY: A STUDY IN NEVSEHIR PROVINCE

In this study, the GIS mapping of the energy use efficiency by the farms producing potato in Turkey in Nevsehir's Central, Derinkuyu, Urgup districts and towns were determined. In the study, survey, questionnaire, observation, measurement and calculation methods were employed. Based on the "Proportional Sampling Method", the study took place in Nevsehir's Central, Derinkuyu and Urgup districts, where 9 villages were randomly selected from each district, combining to make up a total number of 27 villages and 189 farms in 2016 production season. Energy use efficiency, energy productivity, specific energy and net energy in potato production were calculated as 1.58, 0.50 kg MJ(-1), 2 MJ kg(-1) and 40717.69 MJ ha(-1), respectively. The coordinates of the studied potato production areas were acquired with the help of Global Positioning System (GPS) and the coordinate values were transferred to the Digital Elevation Model in digital environment. Energy values and spatial points were processed and these location data were geo-statistically evaluated in Arc GIS 10.3.1 GIS Software. In literature search has indicated that there was never any detailed study conducted on determining the energy use efficiency of the potato production areas in Nevsehir and on establishing spatial energy distribution maps in GIS Mapping.
