Sažetak
Eastern Croatia region contains soils of different properties which have need for specific tillage and fertilization treatments. Our investigations were conducted under field conditions on Zupanja hypogley in four replications. They included five soil tillage (the main factor A: basic experimental plot 4320 m2) and three nitrogen (N) fertilization (the subfactor B) for winter wheat (Triticum aestivum L.) after soybeans (Glycine max L.) as a preceding crop (four growing seasons from 1992/1993 to 1995/1996) as follows: A1=conventional tillage (ploughing to 20 cm depth, diskharrowing and standard sowing) ; A2=diskharrowing and standard sowing ; A3=tillage by multitiller with chisel, standard sowing ; A4=soil tillage and sowing by RAU- Rotosem ; A5=ploughing to the depth of 20 cm + A4 ; N fertilization (kg N ha-1) in amounts 140 (B1), 170 (B2) and 200 (B3) with constant fertilization of phosphorus (150 kg P2O5 ha-1) and potassium (100 kg K2O ha-1). Wheat grain yields (4-year means) as affected by tillage were as follows: 6.00 (A1), 5.79 (A2), 5.65 (A3), 5.61 (A4) and 5.90 t ha-1 (A5). Significant differences of yields were found only in the first year of testing. Nitrogen fertilization resulted by non-significant differences of yields as follows: 5.56 t ha-1 (B1), 5.85 t ha-1 (B2) and 5.96 t ha-1 (B3). Our conclusion is that under certain environmental conditions it is possible to apply reduced soil tillage and moderate N fertilization.
