Abstract
Bu araştırma Bursa yöresinde kolzanın buğday ve ayçiçeği ekim nöbetinde gübre gereksinimini saptamak amacıyla 1994 1995 ekim mevsiminde yürütülmüştür. Dört bloklu faktöryel düzende yürütülen bu araştırmada dört farklı azot dozu 0,6,12 ve 18 kg N'da ve üç farklı fosfor potasyum kombinasyonu 0,6,12 kg P-K/ da kullanılmıştır.Çalışmada tane verimi yanında vegatatif ve generatif gelişme ile ilgili altı farklı karakter de gözlenmiştir. Bunlar bitki boyu yan dal sayısı ana sapta harnup sayısı harnup başına tane sayısı 1000 tane ağırlığı tane verimi ve çiçeklenme süresidir. Gübre dozlarına ve ön bitkiye göre gözlenen özelliklerde farklılık meydana geldiği belirlenmiştir. Azot dozu arttıkça gözlenen bütün özelliklerde artışlar meydana gelmiştir. En Yüksek tane verimi 12 ve 18 kg/ da azot dozlarında elde edilmiştir. Ancak fosfor potasyum kombinasyonlarında verim farklılığı görülmemiştir.
In order to determine the fertilizer needs of rapeseed in the rotation system of wheat and sunflower this rpsearch was conducted in 1994~1995 growing season under non-irrigated conditions of Bursa. In the experıment desıgned in a factorial design with four replicates , four rates of nitrogen < 0, 6, 12 and 18 kg/da ) and three rates of phosphorus-potassium combinations < O, 6, 12 kg/da ) were applied after wheat and sunflower harvested. In this research the seed yield and additional six different vegetative and generative charaçters were observed These were consesced of Plant height number of branches , pod number per plant, number of seeds per pod , 1000 seed weight seed yield and first flowering period. The result showed that the fertilizer rates and the preseeding crops ( wheat and sunflower > haye effected ali of the traits observed. As the rates of nitrogen increased , so did the yield components significantly Maximum seed yield was obtained at nitrogen levels of 18 kg/da and 12kg/da but effect of phoshorus potassium combinations was not significiant.
