Sažetak
Five soil tillage systems were compared during 1996-1998 in maize and winter wheat production on anthropogenic Luvisol in north-west Slavonia, Croatia. Tillage systems and implements were: 1. conventional system - plough, discharrow and combined implement (CT), 2. reduced conventional system - plough and combined implement (RCT), 3. conservation system I - chisel plough and power harrow (CPH), 4. conservation system II - chisel plough and multitiller (CMT), 5. direct drilling - direct drill (DD). The aim of testing was comparison of different tillage systems energy requirement and its influence on yield. Results indicate that conventional tillage system was the greatest energy consumer. Comparing to conventional tillage system, reduced system with plough and combined implement required 16.1% less, conservation system I with chisel plough and power harrow 26.9% less, conservation system II with chisel plough and multitiller 40.8% less, while no-till system required even 85.1% less energy per hectare. The greatest yield of maize, 7.78 t/ha, achieved conventional tillage system while next to it was conservation system II with 7.77 t/ha. No-till system achieved 7.56 t/ha, while conservation system I achieved yield of 7.54 t/ha. The lowest maize yield of 7.17 t/ha achieved reduced system. Second year the greatest yield of winter wheat, 5.89 t/ha, achieved conservation tillage system II. Next to it was conventional system with 5.75 t/ha. No-till achieved 5.73 t/ha, while conservation system I achieved yield of 5.51 t/ha. The lowest yield of 5.27 t/ha achieved reduced system.
