Results of two-year trials (1991 to 1993) conducted with five winter wheat varieties in which the effect of different ways of seeding (muldboard, band and disc) and weather conditions of the year on formation and reduction of tillers and final grain yield were investigated showed statistically insignificant effect of ways of seeding and statistically highly significant effect of varieties and conditions of the year on maximum number of tillers, number of productive tillers and resulting grain yield. Investigated varieties gave maximum grain yields in band seeding with average yield of 6.72 t/ha, differences in grain yields between different ways of seeding were insignificant (statistically insignificant). Livia was the variety with the highest intensity of tillering in trials conducted (6.28 tillers per plant) but at the same time it had highest reduction of number of tillers (68.19 %), in which maximum grain yield of 7.00 t/ha was recorded, what is higher by 9.7 % compared with minimum grain yield (6.38 t/ha).
