Sažetak
An experiment with five different tillage systems and its influence on soil water availability in the rhizosphere of silty loam (Albic Luvisol) was in the period of 1997-2000 in north-west Slavonia made. The compared tillage systems were: 1. conventional tillage (CT), 2. reduced tillage (RT), 3. conservation tillage I (CP), 4. conservation tillage II (CM), 5. no-tillage system (NT). The crop rotation was winter wheat (Triticum aestivum L.) - soybean (Glycine max L.) - winter wheat. The gravimetric soil water content was measured at 0-5 cm, 15-20 cm and 30-35 cm layers and the percentage of avilable water capacity was calculated. The available soil water at all the three monitored layers during the all experimental seasons was the greatest under the NT system and the lowest under the CT system. The most frequent trend of the available soil water was NT>CM>CP>RT>CT. The highest yield in all the experimental years was achieved under the CM tillage system, while the lowest yield was achieved under the RT system.
