Nitrogen-Use Efficiencies of Bread and Durum Wheat Cultivars Grown in Çukurova Region
Abstract
The present study was carried out to determine nitrogen-use efficiencies (NUE) of common bread and durum wheat cultivars grown in Çukurova region. Experiments were conducted at Doğankent Experimental Station of Eastern Mediterranean Agricultural Research Institute during the growing seasons of 2000-2001 and 2001-2002. Seven bread wheat cultivars (Adana-99, Ceyhan-99, Yüreğir-89, Doğankent-1, Panda, Seyhan-95 and Genç-99) and three durum wheat cultivars (Amanos-97, Fuatbey-2000 and Gediz-75) were used as the plant material of the study. Experiments were carried out in randomized block design with 3 replications. Nitrogen (N) doses (0, 5, 10, 20 kg da-1) were randomly placed in main plots and wheat cultivars were placed in sub-plots.
As a general average, wheat cultivars had NUE values of between 29-66%. NUE values of much precipitated (737.4 mm) year were lower than the NUE values of less precipitated (346.7 mm) year (58% and 34%). The cultivars Adana-99 and Ceyhan-99 had the highest NUE values as general average. These two cultivars had both higher nitrogen-uptake efficiency (NUpE) and nitrogen-utilization efficiency (NUtE) than the year averages.Keywords
