In 1999 the effect of main and foliar fertilizers on the yield and content of nutrients of white cabbage 'Eton' F1 was tested. In spring complex fertilizer Kemira 'Horti 3' and mechanical mixture of straight fertilizer were used. Three times during the growing period foliar fertilizers from 'Kemira' company calcium nitrate 'X-lehevaetis' and 'Hydro' were sprayed. Depending on fertilization type the yield of white cabbage was 4.1...6.4 kg m (-2). The increase of white cabbage yield fertilized by Kemira 'Horti 3' was 1.3 kg m (-2) compared to mixed fertilizer. The dry matter content of cabbage fluctuated between 8.73 and 9.1 per cent. The content of dry matter and nitrate of cabbage increased by using mechanical mixture of straight fertilizer. In our tests the yield and content of nutrients was not significantly affected by the application of foliar fertilizer
