Abstract
The effect of conventional tillage, simplified tillage and direct sowing on the yields of 7 winter wheat cultivars (Elena, Kobra, Maltanka, Mikon, Izolda, Aleta and Sakwa) was determined in Poland, during 2000-02. Tillage simplifications introduced after cereal forecrops (oat and spring wheat) decreased the yields of wheat cultivars. After cereal forecrops, the cultivars characterized by higher yielding in plough cultivation tended to give higher yields also in simplified tillage variants. Differentiated partial coefficients of yield components in multiple regression equations point to a variable reaction of wheat cultivars to simplified tillage. At periodical precipitation deficits the number of ears per square metre as well as the weight and number of grains in an ear appeared to exert the greatest influence on the yields of cultivars
