AB - Energy and exergy analysis gives valuable information to policy maker in  order to make the right decision with regard to agricultural policies. In  this present study, an investigation was carried out to reveal the energy  and exergy consumption of some agricultural crops cultivated in Turkey for  the year of 2014. Wheat, corn, cotton, sunflower, potato and sugar beet are  the massively harvested crops in Turkey. Therefore, energy and exergy  analysis of these crops were evaluated. The analysis was based on the  thermodynamics concept and covers the direct energy usage (i.e. electricity  for pumping and diesel fuel for farm machinery) in the agricultural  activity. Three different irrigation methods namely, flooding, sprinkler,  and drip irrigation were considered. According to the results of the present  study, wheat is the most energy and exergy consuming crop and potato is the  least energy and exergy consuming crop. In addition to this flooding  irrigation method requires the least energy and exergy values. On the other  hand, sprinkler irrigation method requires the most energy and exergy  values.
