Özet:
This research aimed to make an energy input-output analysis of different tillage methods on the secondary crop sunflower production during production years in 2010 and 2012. In order to determine energy input-output of sunflower, the treatments were performed in Thrace region of Turkey to determine the amount of energy use efficiency for different tillage methods. This study was perform to evaluate the effects of different tillage methods on energy use, the energy input-output ratios and profitability for sunflower production. The research was planned as a completely randomized parcel design with four tillage systems in four replications. The effects of tillage were found on energy indicators. Avarege of the highest energy use efficiency (1.36), energy productivity (0.054 kg MJ(-1)) and net energy (16039.23 MJ) were found in T-4 method but T-1 had the lowest. T-4 method should be supported and recommended for the energy sustainability of sunflower agriculture.
