1 Ankara Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü, Ankara - This research was conducted at experimental fields of Department of Agronomy, Faculty of Agriculture, University of Ankara in 2000. The aim of the research was to determine effects of different sowing dates (23 March, 28 March and 11 April) and row spacings (30 and 40 cm) on yield and yield components of some high oil quality turniprape (Brassica campestris L.) varieties. In the study, three spring turniprape varieties (Agat, Mammut and Harmoni) were used as plant material. The experiment was established according to split - split plot desing of randomized blocks with three replications during spring season. The results showed significant differences among varieties, sowing dates and row spacings. The highest value for first blooming was obtained from variety Harmoni (54.33 days), while the lowest value was obtained from variety Agat (50.33 days). The highest seed yield per decare was found for variety Agat sown at earlier date with 30cm row spacing with yield of 128.05 kg/da. The lowest value was recorded from last sown variety Harmoni with row spacing of 40 cm and yield of 34.92 kg/da. The research indicates that delayed sowing resulted in decreases on the investigated traits. Keywords : Turniprape (Brassica campestris L.), sowing date, row spacing, variety, yield, oil ratio
