Energy use efficiency analysis of wheat production with different soil tillage systems

In this study, the four different tillage systems (1 (no-tillage (DE) (no till planter); 2) conservational tillage system (KT) (chisel+ disc harrow+planting); 3) reduced soil tillage system (RT) (rotovator+planting); 4) conventional soil tillage system (GT) (mouldboard plough+ disc harrow+planting)] were compared in terms of energy use efficiency under dry farming condition for Bezostaja-1 wheat cultivar in Sivas province. Energy ratio, specific energy, energy productivity, net energy and energy profitability were taken into consideration as energy parameters. The highest energy input was obtained as fertilizer, seed, and fuel +oil energies in all tillage systems for wheat farming, respectively. According to results; the highest and lowest energy values are obtained in AT (4.87) and GT (4.53) systems respectively, while the highest specific energy value was obtained in the GT (3.25 MJ kg-1) and the lowest specific energy value was obtained in the AT (3.02) MJ kg-1) system. Soil tillage systems are listed in terms of net energy value (MJ) as GT> AT> KT> DE from high value to low value depending on net energy. In Sivas province, no-till, reduced tillage and conservational tillage systems could be used instead of the traditional tillage method in wheat farming according to the energy ratio, specific energy, energy efficiency and energy profitability values
