EFFECT OF DIFFERENT TILLAGE AND STRAW MANAGEMENT ON THE YIELD OF WINTER WHEAT

The impacts on yields of winter wheat planted after winter wheat and safflower, are analysed in thesis, concentrating on the effect of different soil tillage combined by the use of fugicides. The monitoring proceeded in the years 2006-2008 within the frame of a field experiment. Two technologies of soil tillage were focused on: (I) conventional tillage and (II) minimum tillage, as well as two methods of fungicide treatment: (1) with treatment and (2) no treatment. Higher yields of winter wheat were reached for both technologies of soil tillage by planting after safflower. Higher yields after winter wheat were obtained for conventional tillage, whereas the yields after sufflower were higher for minimum tillage with loosening. Considering both preceding crops and conventional tillage, slightly higher yields were gained for application of no fungicides. For minimum tillage with shallow loosening, higher yields were achieved after applying fungicides.
