The aim of this thesis was to elaborate analysis of cultivation of cereal crops and spring barley in the Czech Republic, EU and worldwide, and to evaluate the impact of different methods of tillage on yields and economics of cultivation of spring barley. The effect of different soil tillage intensity on yields and economics of cultivation of spring barley was observed in the long -- term experiment. This experiment was conducted on loamy chernozem soil in sugar-beet producing region in Ivanovice na Hané. Yields obtained between years 1990 -- 2014 were evaluated. Spring barley was grown in three crop rotations. The forecrop of the spring barley was always sugar beet grown after maize for silage, winter wheat and spring barley. Four variants of tillage were evaluated: ploughing to the depth of 0,22 m, ploughing to the depth of 0,15 m, straight sowing into non-tilled soil and shallow loosening soil to the depth of 0,10 m. In all three crop rotations, the highest average yield was obtained in variant - ploughing to the depth of 0,15 m and the lowest average yield was obtained in variant - ploughing to the depth of 0,22 m. For the economic evaluation of the impact of different soil tillage intensities were determined variable costs, revenues and gross margins. In all three crop rotations the lowest gross margins were achieved in variant with ploughing to the depth of 0,22 m. In the crop rotation of maize for silage -- sugar beet -- spring barley and in the crop rotation of spring barley -- sugar beet -- spring barley were the highest gross margins determined in variant with direct sowing into non-tilled soil. In the crop station of winter wheat -- sugar beet -- spring barley were the highest gross margins determined in variant shallow loosening soil to the depth of 0,10 m. The results indicate that in these soil and climatic conditions, the reduction of intensity of tillage for spring barley grown after sugar beet is sustainable alternative to the traditional method of tillage.
