Energy and economic analysis in rose production in Isparta province where there is intensive-rose production were performed. A total of 11 villages from Isparta Centre, Atabey, Keciborlu, Gönen, districts of Isparta province were surveyed by applying a face to face questionnaire method with 109 rose growers. Results revealed that total energy consumed per hectare for rose production was 29313.12 MJ ha-1 and the most energy demanding input was chemical fertilizers (46.67%), especially nitrogen (39.81%). Energy consumption due to diesel fuel was 21.87% of the total energy input. Total bioenergy output was calculated as 21150.69 MJ ha-1 considering its yield (5041.88 kg ha-1) and its energy contents (4.20 MJ kg -1) Energy use efficiency, specific energy and energy productively of rose production were found to be 0.72, 5.81 MJ kg-1 and 0.17 kg MJ-1, respectively. It was concluded that the direct and indirect energy inputs were 36.08 and 58.90% of the total energy input, respectively. Renewable energy sources among the inputs constituted 16.43% of the total energy whereas non-renewable resources among the inputs constituted 16.43% of the energy whereas non-renewable resources (chemical fertilizers and diesel fuel) constituted 78.55% of total energy input. Result showed that net return from rose production in the surveyed farms was at satisfying level. Benefit to cost ratio was found to be 1.58. © 2006 Asian Network for Scientific Information.
