Field trials were conducted to test the effect of different rates of fertilizer N and the use of retardant ccc and fungicides on the growth and yield of fourteen varieties of winter wheat. Comparatively high winter wheat grain yields (7.0-9.9 t haE-1) of adequate quality (gluten content above 30%) were obtained from all the varieties tested. Complex application of both retardant and fungicides resulted in rapid increase of the efficiency of the applied fertilizer N, reaching its maximum up to 21.7 kg of wheat grain per 1 kg of applied N.
