Six field experiments with foliar application of winter raps were going on in 1992 and 1993. Split application of Mg in the dose 1 + 2 or 2 + 1 at the stage of rozeta (EC 14) and budding (EC 55) increased seeds yield by about 15%. However, the lack of positive quality seeds response to foliar Mg application suggests necessity of further increase of applied dose.
