摘要：

The experiment with hybrid winter oilseed rape Marcopolos (KWS) evaluates five growing technologies. It is sowing into plowing and into stubble plowing with use of coulter sowing machine Oyord and sowing machine Farmet Falcon 6 with deep cultivation in strips (strip sowing). Sowing rate (50 and 80 seeds/m2), autumn nitrogen dose (0 and 46 kg N/ha), nitrogen fertilisation into the soil during sowing and autumn dose of azole regulator were also evaluated. Strip sowing into stubble plowing combined with higher sowing rate, autumn nitrogen dose and dual autumn regulation overcomes in seed yield the traditional plowing technology Oyord by 750 kg/ha (15.3 %).
