Bazı ekmeklik buğday çeşitlerinin potasyum kullanım etkinliliği
Deneme 2009/10 ve 2010/11 yıllarında iki vejetasyon döneminde yürütülmüştür. Çalışmanın amacı yarı kurak iklim koşullarında bazı ekmeklik buğday çeşitlerinin tane verimi, K-kullanım etkinliği, K-alım etkinliği ve K’dan yararlanma etkinliğine potasyum K dozlarının kontrol-0, 25, 50 ve 75 kg/ha etkisini araştırma amacıyla yürütülmüştür. Deneme tesadüf bloklarında bölünmüş parseller deneme desenine göre 3 tekerrürlü olarak, ana parsellere potasyum dozları ve ana parselleri içerindeki alt parsellere buğday çeşitleri gelecek şekilde kurulmuştur. Buğday çeşitleri arasında hem 2009/10’da hem de 2010/11’de en yüksek tane verimi, K-kullanım etkinliği ve K’dan yararlanma etkinliği Altay-2000 çeşidinden, en yüksek K-alım etkinliği Sultan çeşidinden elde edilmiştir. Potasyum dozları arasında, hem 2009/10’da hem de 2010/11’de en yüksek tane verimi, K-kullanım etkinliği ve K’dan yararlanma etkinliği 50 ve 75 kg/ha K dozlarından, en yüksek K-alım etkinliği 25 kg/ha K dozunda tespit edilmiştir. Çeşit x K dozu interaksiyonunun buğdayın tane verimi, K-kullanım etkinliği, K-alım etkinliği ve K’ dan yararlanma etkinliği üzerine etkisi her iki yılda da istatistiksel olarak p

Potassium-use efficiency of some bread wheat cultivars
The experiment was carried out in two vegetation seasons, years of 2009/10 and 2010/11. The main purpose of the study was to investigate the effects of potassium K doses a control-0, 25, 50 and 75 kg ha-1 on grain yield, K-use efficiency, K-uptake efficiency and K-utilization efficiency of some bread wheat cultivars Gerek-79, Gün-91, Harmankaya, Altay-2000, Yıldız and Sultan under the semi-arid climatic conditions. The experiment was set up according to a randomized complete block design in a split-plot arrangement with three replicates, where potassium doses were main plots while the wheat cultivars were in subplots split within main plots. Of the wheat cultivars, the highest grain yield, the highest K-use efficiency and the highest K-utilization efficiency were obtained from Altay-2000 in both 2009/10 and 2010/11, the highest K-uptake efficiency from the Sultan during 2009/10 and Gerek-79 during 2010/11. Of the potassium doses, while the highest grain yield, the highest K-use efficiency and the highest Kutilization efficiency were determined from the 50 and 75 kg ha-1 K doses, the highest K-uptake efficiency was obtained from the 25 kg ha-1 K dose in both 2009/10 and 2010/11. The effect of the cultivars x K dose interactions on grain yield, K-use efficiency, K-uptake efficiency and Kutilization efficiency of wheat were statistically p
