Abstract:

Field trials, to investigate the effect of microfertilisers on the oil content of seeds of the oilseed rape cultivar ‘Mascot’, were carried out at the Department of Field Crop Husbandry in 2002-2003. We used in our trial 7 different microfertilisers. Prior to the sowing, the field was sprayed with herbicide EK Trifluralin and mineral fertiliser OptiCropNPK 21-08-12+S+Mg+B+Ca, calculating 120 kg N ha-1. Plants were treated with microfertilisers on 26 June. Analyses of test results revealed that different microelements influenced the oil content of rape seeds. The positive effect was noted in variants where rape plants were treated with micronutrients and micronutrients mixtures. The highest oil content, 43.4% of seeds dry matter, had Molybdenum-treated rape.
