Abstract
Bu deneme, Uludağ Üniversitesi Ziraat Fakültesi’nin Gö1iikle (Bursa)'deki Araştırma ve Uygulama Çiftliğinde yetiştirilen Vratsa buğday çeşidinin dane verimi üzerine değişik azotlu gübrelerin etkilerini araştırmak amacıyla yürütülmüştür. Tarla denemesi tesadüf blokları deneme desenine göre dört tekerrürlü olarak kurulmuş ve ekimle birlikte bütün parsellere 4 kg N/da hesabıyla diamonyum fosfat (% 18 N, % 46 P2Os) gübresi verilmiştir. ilkbahar gübresi olarak kardeşleme döneminde üç azotlu gübre (amonyum sülfat, % 21 N; amonyum nitrat, % 26 N ve üre, % 46 N), üç ayrı dozda (9, 12 ve 15 kg N/da) uygulanmıştır . Araştırma sonuçlarına göre, buğdayın dane verimi üzerine etkileri yönünden azotlu gübre/er arasında istatistiksel olarak önemli bir farklılığın bulunmadığı, ancak bugünkü gübre fiyatlan dikkate alındığında, üre gübresinin daha ekonomik olduğu belirlenmiştir.
This experiment was carried out to investigate the effects of different nitrogen fertilizers on the yield of winter wheat cv. Vratsa grown at tlıe Experimental Farm of Agriculturel Faculty of Uludağ University in Görükle-Bursa. The field experiment was established in randomized block design with four replications. At sowing, 4 kg/da nitrogen was applied as diammonium phosphate (18 % N, 46 % P2O5)· As a spring fertilizer, three nitrogen fertilizers ( ammonium sulphate, 21 % N; ammonium nitrate, 26 % N; and urea, 46 % N) were applied at three levels (9, 12 and 15 kg N/da) to the plots at tillering stage. It was found that there were no statistically significant differences in wheat yield between the nitrogen fertilizers applied. However, when current fertilizer prices were taken into account, urea seemed to be more economic.
