Abstract

This paper presents the results of the investigated morphological and phenological
traits of fiber flax cultivars with and without topdressing by nitrogen (0 i 27 kg/ha).
Cultivars trials were set up in two years (2004-2005) and locations (Zagreb and
Posavski Bregi). The trials involved five foreign cultivars of fiber flax (Viking, Venica,
Agatha, Electra i Ilona) and were set up according to RCBD in four replications.
According to the results of the research into the morphological and phenological
traits of fiber flax, significant differences were established between the cultivars and
without and with topdressing by nitrogen. Significantly highest values for seed yield
were recorded in cultivars Ilona in Zagreb and Electra in Posavski Bregi. Higher values
of the seed yield, number of capsules per plant, number of seed per capsules, 1000 seed
weight and growth after 60 days were obtained with topdressing. Cultivars Viking and
Venica belong to the early vegetation ripening group, while cultivars Agatha, Electra
and Ilona belong to the full vegetation ripening group.
