In field experiments made on a degraded chernozem the authors tested the response of 3 Polish cultivars of winter wheat (Gama, Emika, Liwilla) to nitrogen fertilization - 90 kg N per ha, applied through the soil as a whole or 50 percent by foliar spray. The authors found that the method of applying nitrogen did not affect its effectiveness. A somewhat better utilization of nitrogen did, it is true, appear during its foliar application jointly with the retardant and the fungicide. A comparatively positive effect on the yield of wheat grain was obtained by the retardant and the fungicide applied in the control object i.e. without the nitrogen fertilization
