Trakya' da alabaş (Brassica oleraceae var. gongylodes L.) yetiştirme olanağı ve uygun çeşitlerin belirlenmesi

Çalışma, Trakya koşullarında alabaş yetiştirme olasılığını ve uygun çeşitleri belirlemek amacıyla 2000 ile 2002 yıllan arasında ilkbahar ve sonbahar yetiştirme döneminde yürütülmüştür. Her bir dönemde dokuz alabaş çeşidi verim ve bazı yumru ve yaprak özellikleri bakımından değerlendirilmiştir. Trakya koşullarında alabaşın başarılı bir şekilde yetiştirilebileceği belirlenmiştir. En yüksek yaprak ağırlığı Erko'dan elde edilirken, yıl ve döneme bağlı olarak 471.4 ile 986.0 g arası bitki ağırlığı, 340,2 ile 899.9 g arası yumru ağırlığı, 87.3 ile 125.2 mm arası yumru çapı ve 7.72 ile 20.7 kg parsel verimi ile Rapidstar en uygun çeşit olarak belirlenmiştir.

Determination on suitable varieties and the possibility of kohlrabi (Brassica oleraceae var. gongylodes L.) growing in Trakya(Thrace) Region

A study was carried out to investigate the possibility of kohlrabi growing and to determine the suitable cultivars under Trakya conditions during the spring and autumn growing periods between 2000 and 2002. In each period, nine kohlrabi cultivars were evaluated with respect to yield and some tuber and leaf characteristics. It was observed that kohlrabi can be successfully grown under Trakya conditions. While the highest leaf weight was obtained from Erko, the variety Rapidstar which had plant weight between 471.4 and 986.0 g, tuber weight between 340.2 and 899.9 g, tuber diameter between 87.3 and 125.2 mm and yield between 7.72 and 20.07 kg/plot, as depending on different year and season was the best suitable cultivar for the Region.
