Ekmeklik Buğday Triticum aestivum L. ' da Değişik Su ve Azot Uygulamalarının Tane Verimine Etkileri

Abstract

1993-1995 y ı lları aras ı nda A. Ü. Ziraat Fakültesi Tarla Bitkileri Bölümü Deneme Tarlas ı ile Kenan Evren Araşt ı rma ve Uygulama Çiftliğ i'nde yürütülen bu çal ışmada, buğdayda farkl ı su ve azotlu gübre uygulamaları n ı n tane verimine etkileri belirlenmi ştir. Bu amaçla materyal olarak Bezostaja 1, Gerek 79 ve Gün 91 çe şitleri kullan ı lm ış , sulama uygulamaları olarak O, 20, ve 40 mm, azot uygulamalar ı olarak ta 4 kg/da saf N, 6 kg/da saf N ve 8 kg/da saf N dozlar ı uygulanm ışt ı r. Araşt ı rma sonuçlar ı na göre, tane verimi yönünden artan azot ve su miktarlar ı na bağ l ı olarak istatistiki yönden önemli art ış lar gözlenmiştir. En yüksek tane verimi N2 6 kg/da saf N ve N3 8 kg/da saf N dozlar ı ile S2 40 mm sulama uygulamalar ı yla Gerek 79 çeş idinden elde edilmi ştir.

Effects of Various Irrigation and Nitrogen Applications on Grain Yield of Common Wheat Triticum aestivum L.

Abstract

The effects of different irrigation and nitrogen fertilizer applications on grain yield of wheat were determined in this research which was carried out at the Experimental Field of the Department of Agronomy and Kenan Evren Research and Application Farm, Faculty of Agriculture, University of Ankara during 1993-1995. The seeds of cv. Bezostaja 1, Gerek 79 and Gün 91 were used as material and 0,20 and 40 mm irrigation applications and also 4 kg/da, 6 kg/da and 8 kg/da nitrogen doses were applied. According to the results of this research; significant increases on grain yield were determined ststistically in regard to exceeding nitrogen and irrigation applications. Gerek 79 had the highest grain yield with N2 6 kg/da N and N3 8 kg/da N nitrogen doses and S2 40 mm irrigation applications.
