Abstract

This study was conducted to determine the effect of nitrogen on agronomic characters, yield and quality parameters at two malting barley cultivars suitable for Meander Valley ecological conditions, in 2003- 2004. Four nitrogen levels (40, 80, 120 and 160 kg ha -1) and control were used. Nitrogen fertilizers were applied at two times as pre-planting and tillering stage. A field experiment was arranged as a split plot block design with three replications. The plant height, flag leaf area, yield, thousand kernel weight, test weight, protein content were measured characters. It was obtained that Serife Hanim had higher yield and malting quality than Kaya in the region and 100-112 kg ha -1 nitrogen level was sufficient to get reasonable yield and best quality. Key words: Barley, yield, yield components, quality, nitrogen fertilization, malting barley.

Biralık Arpada Farklı Azot Dozlarının Verim, Tarımsal Özellikler ve Kalite Üzerine Etkisi

Abstract

Bu çalışma, Büyük Menderes havzasına uygun iki biralık arpa çeşidinde azotun verim, tarımsal özellikler ve
kalite üzerine etkisini belirlemek amacıyla 2003-2004 yetiştirme periyodunda yürütülmüştür. Dört farklı azot
dozu (40, 80, 120 ve 160 kg ha ) ve kontrol kullanılmıştır. Azotlu gübreleme ekim öncesi ve kardeşlenme olmak
üzere iki farklı dönemde uygulandı. Deneme 3 yinelemeli olarak Bölünmüş Parseller Deneme Deseninde
yürütüldü. Bitki boyu, bayrak yaprağı alanı, verim, bin tane ağırlığı, hektolitre ağırlığı ve protein içeriği
incelendi. Şerife Hanım çeşidinin malt kalitesi ve verim yönünden Kaya çeşidinden daha iyi özelliklere sahip
olduğu ve 100112 kg/ha azot dozunun en iyi sonucu verdiği saptandı.
