Bu çalışma farklı ekim zamanı ve tohumluk miktarının iki farklı kanola çeşidinin verim, yağ ve protein oranı üzerine etkisini belirlemek amacıyla 2014/2015 ve 2015/2016 yetiştirme periyodunda Aydın Adnan Menderes Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama alanlarında yürütülmüştür. Deneme deseni olarak 4 yinelemeli Bölünen Bölünmüş Parseller kullanılmıştır. Ekim zamanları (erken ve geç) ana parsellerde, çeşitler (NK Petrol ve NK Caravel) alt parsellerde ve tohumluk miktarları (300 g, 500 g, 700 g, 900 g ve 1100 g da-1) alt-alt parsellerde yer almıştır. Denemenin yürütüldüğü her iki yılda da erken ekim zamanında uygulanan 700 g da-1 tohumluk miktarı her iki çeşitte de en yüksek verimi vermiştir. Ham yağ oranı yönünden ekim zamanı x çeşit interaksiyonu önemli bulunmuş ve en yüksek ham yağ oranları her iki yılda olmak üzere erken ekim zamanında NK Petrol kanola çeşidinden (%43.34 - %43.54) elde edilmiştir. Protein içeriği yönünden çalışmada incelenen faktörlerin ve interaksiyonlarının önemli olmadığı ve protein oranlarının %19.10 ile %23.72 arasında değiştiği saptanmıştır. Sonuç olarak, kışlık kanola yetiştiriciliğinde verim ve kalite özellikleri yönünden ekimin mümkün olduğu kadar erken yapılması ve 700 g da-1 tohumluk miktarının uygulanması kanısına varılmıştır. Ayrıca, erken ekimlerde NK Petrol buna karşın geç ekimlerde NK Caravel çeşidinin kullanılması önerilmiştir.

The Effect of Sowing Date, Cultivar and Seed Rate on Yield and Quality Characteristics in Rapeseed (Brassica napus L.)

Öz

This study was carried out to determine the effect of different sowing dates and seeding rate on seed yield, oil and protein contents of seed in two rapeseed cultivars in the field of experiment and application of Aydin Adnan Menderes University Faculty of Agriculture during 2014/2015 and 2015/2016. The experiment was the split-split-plot design with 4 replications. The sowing dates, cultivars and seeding rates were arranged to main, sub and sub-sub plots, respectively. This experiment was conducted applying two sowing dates (early and late), two winter type cultivars (NK Petrol and NK Caravel) and five seeding rates (3, 5, 7, 9 and 11 kg ha-1). The early sowing date and 7.0 kg ha-1 seeding rate given the highest seed yield for both cultivars based on two-year results. The interaction between sowing dates and cultivars for crude oil rate was significant, and the highest crude oil rate was recorded in NK Petrol cultivar (43.34 - 43.54%) at the first sowing date in both years. Non-significant protein content for all factors and interactions varied from 19.10% to 23.72%. Finally, it was recommended the earliest possible sowing with 7.0 kg ha-1 seeding rate for seed yield and quality in winter rapeseed growing. Moreover, it was recommended that NK Petrol for early sowing dates and NK Caravel for late sowing dates should be used as a cultivar.
