The response of winter wheat to sowing after cereals in the three-field crop rotation links was investigated. It was found that the wheat cultivation after cereals with a field bean as a forecrop led to a drop of its yield. The worst forecrop proved to be spring barley. The decrease of the unit productivity of grain occurred in consequence of heavier infestation of winter wheat with stem foot disease and of a growth of the weediness degree of the field. An increase by 50% of the NPK level increased winter wheat grain yields on the average by 7.2%. Fertilization was more efective when wheat was cultivated after cereals than after field bean
