Input-output energy analysis of cherries production in Tokat Province of Turkey

In this study, the cherries production in Turkey, and the energy equivalences of input used in this production are investigated. The data were collected through a survey study from the business enterprises in the Tokat region, where intensive cherries production takes place. The following results were obtained at the end of the study: with 42%, the input of fertilizer is the highest within the energy equivalences of input used in cherries production. This is followed by electricity and fuel (diesel) with 22% and 21%, respectively. The energy equivalences of chemicals, human labour, machinery and irrigation water were found to be low. The input/output ratio in the production of cherries was found as 0.96. This shows that the inputs used in the production of cherries are not used efficiently. Hence, human resources should be improved, sustainable agriculture should be extended and conscious farming should be provided. The extension staff has very important responsibilities on this subject. (C) 2008 Elsevier Ltd. All rights reserved.
