The investigation aimed at analyzing the variability in winter wheat cultivars yielding as
depending on the tillage system, density and term of sowing. There were used two systems of
tillage: conventional (plughing) and simplified. In each of them regarded were the following factors:
I – terms of sowing: a) 14–16 September (early sowing); b) 1–3 October (optimum sowing); 15–17
October (delayed sowing); two sowing densities: A – 3000 grains per a square neter; B-450 grains
per a square meter; III – winter wheat cultivars: Finezja, Rywalka, Kobiera, Satyna, Bogatka,
Zawisza. At conventional tillage the optimum sowing term appeared conducive to stable yields of
winter wheat, while delayted sowing term at simplified tillage and early at plough tillage were
bringing about a considerable differentiation in the yields of the cultivars tested. The cultivar
Finezja sown at the early term in decreased density show a tendency to produce higher yields as
compared to those obtained at the optimum term, irrespective of the system of tillage. On the other
hand, higher yields of the Satyna cultivar were obtained in conditions of early sowing term and
simplified tillage. Cluster analysis revealed that the yields of Finezja anad Rywalka cultivars were
depending on the sowing density to a lesser degree than those of the other cultivars tested.
