The effect of EurepGAP standards on energy input use: A comparative analysis between certified and uncertified greenhouse tomato producers in Turkey

The aim of this study was to compare the energy use on greenhouse tomato production between EurepGAP certified and uncertified producer groups in Turkey in terms of energy ratio, benefit/cost ratio and amount of renewable energy use. Total energy requirement on EurepGAP certified producers group was 90,288.5 MJ/ha whereas 126,311.5 MJ/ha was consumed on uncertified producers group i.e. 29% higher energy input was used on uncertified producers than that of certified ones. The energy ratio of 0.79 and 0.72 were achieved on EurepGAP certified and uncertified tomato producer groups, respectively.
