This study was conducted at the Bahri Dagdas International Agriculture Research Institute in the Central Anatolia region of Turkey over a 4-year period to evaluate the effects of tillage on grain yield, yield components, quality and energy indices of winter wheat production. The study utilized a randomized block design with three tillage systems [moldboard plough + combined cultivator and tooth harrow + combined spring tooth harrow and rotary harrow + seeding machine (CT); rotary tiller + seeding machine (RT) and no-till (NT)] in three replications. The tillage system had a significant effect on grain yield (GY), thousand kernel weight (TKW), plant height (PH), number of grains m 2 (NG), number of grains per spike (NGS) and particle size index (PSI), but no significant effect on biomass yield (BY), harvest index (HI), number of spikes n r2 (NS), hectoliter mass (HM), protein content (PC) and dry gluten (DG). Grain quality was affected, to a greater extent, by agro climatic conditions than by tillage system. Energy indices were significantly affected by tillage systems, with NT consuming the least energy for wheat produced (8.20 MJ/kg), and CT consuming the most (11.74 MJ/kg for CT). NT was found to be the most efficient overall tillage system in the region studied; however, conservation tillage of winter wheat can be used to increase productivity with only a minimum energy input.
