Abstract
Bu araştırma Uludağ Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama Çiftliğinde yetiştirilen ekmeklik Otholom buğday çeşidinin verim ve bazı verim öğeleri üzerine, değişik zamanlarda ve artan miktarlarda uygulanan azotlu gübrenin etkisini belirlemek amacıyla yürütülmüştür. Tarla denemesi tesadüf blokları deneme planına göre dört tekerrürlü olarak kurulmuş, ekimle birlikte bütün parsellere 5 kg P2 O5 / da hesabıyla triple süperfosfat verilmiştir. Azot beş ayrı dozda (0, 8, 12. 16 ve 20 kg N/da) uygulanmıştır. Kontrol dışındaki bütün parsellere ekimle birlikte 5 kg N/da hesabıyla üre verilmiştir. Azotun geriye kalanı iki farklı uygulama zamanında verilmiştir (I. Geriye kalan azotun tamamımın kardeşlenme döneminde, ll. Geriye kalan azotun yarısının kardeşlenme, diğer yarısının ise sapa kalkma döneminde). Araştırma sonuçlarına göre, azotun verilme zamanının verim ve bazı verim öğeleri üzerine etkili olmadığı belirlenmiştir. Azot dozlarının ise verim ve verim öğeleri üzerine etkili olduğu, azotun 12 kg N/da dozunun yeterli olduğu saptanmıştır.
This study was carried out to de termine the effects of differenı application times and increming amount of nitragen fertilizer on yield and its components of bread wheat cv. Otholom grown at the Experimental Farm of Agricultural Faculty of Uludag University. The field experiment was established in randomized block design withfour replications. At sowing, phosphorus was applied to all plots at the rate of 5 kg P2 O5/da as triple superphosphate. Nitragen was applied to the plots at five rates (0, 8, 12, 16 and 20 kg N/ da). To all plots (except control) nitragen was applied at sowing at the rate of 5 kg N/da as ürea. The rest of nitragen was applied to the plots at two different application times (I. All of the rest of nitragen at tillering stage, II. Half of the rest of nitragen at tillering and the other half at shoot elongation stages). According to the results obtained, the effects of the application times of nitragen on yield and its components were not to be effective. Nitragen doses signijicantly effected yield and its components and it wasfoımd that 12 kg of N per decare was adequate.
