Sažetak
During the last decade, rapid climatic changes have occurred and through water cycle disturbance strongly affected agricultural production. Appearance of long draught intervals through vegetation periods has been detected. Annual precipitation remained at the same level, but the data indicate the increasing presence of extremely intense rainfall that cannot meet the needs of crops for water. Therefore, it is necessary to devote special attention to management of water that is available during winter time and preserving water quantities for possible draughts intervals during vegetation period. The aim of this research is to determine optimal soil tillage system that will provide sufficient water quantities for crops and increase resilience of agroecosystems. For that reason field experiment with 4 soil tillage systems was set up in Central Croatia. Tillage systems differed in implementation time of separate tillage interventions. Experiment started in 2007 and in 2008 corn was cover crop. During vegetation period soil resistance, soil moisture, bulk density, humus content and yield data were collected. Statistical data analysis showed significant differences of corn yields, hectolitre and absolute weight between treatments. Yields varied from 5.4 to 9.7 t ha-1 depending on tillage system.
