It was found on the base of two-years studies that total input of cumulative energy amounted 2050 MJ per ha on soil tillage as ploughing at medium depth (20-22 cm) with application of complete tillage set. Substitution of medium depth ploughing by chisel with shallow ploughing caused increase of energy input by 24%. Chisel ploughing and rototiller increased energy by 7%. Obtained results proved that application chisel and shallow ploughing together with tillage complete set caused yield increase by 35%, compared to conventional pre-sowing tillage. Technological quality of wheat grain seems to be more differentiated by climatic conditions than by method of pre-sowing tillage
