Abstract: Th e aim of the study was to evaluate the eff ect of diff erent soil tillage on yield of spring barley from a long-term stationary fi eld experiment.Th e experiment was conducted in period from 1990 to 2014 on loamy chernozem soil in a sugar beet growing region.Spring barley was grown in three crop rotations, always aft er sugar beet which was set aft er silage maize, winter wheat and spring barley.Four variants of soil tillage were evaluated: 1. ploughing to the depth of 0.22 m; 2. ploughing to the depth of 0.15 m); 3. direct sowing into non-prepare soil; 4. loosening to the depth of 0,10 m.Infl uence of experimental factors on yield was evaluated in 1990-2014.Infl uence of experimental factors on yields was statistically signifi cant.Th e highest average yield was reached in the crop rotation -spring barley, sugar beet, spring barley and the lowest yield in the crop rotation -silage maize, sugar beet, spring barley.In all three crop rotations the highest average yield was on variant with ploughing to 0.15 m (6.68 t•ha -1 ) and the lowest on variant with ploughing to 0.22 m (6.54 t•ha -1 ).Minimum soil tillage technologies with direct sowing (6.64 t•ha -1 ) and loosening to 0.10 m (6.62 t•ha -1 ) had a middle grain yields.Results of this observation shows that lower intensity of soil tillage in case of spring barley grown aft er sugar beet, under conditions of the given locality, is a suitable alternative to traditional way of soil tillage.
