摘要：This research was undertaken to determine the effects of nitrogen fertilization on semolina yield, and ash and pigment content in durum wheat. The samples were taken a nitrogen fertilization trial over a two years period. Çakmak 79 and Kunduru 1149, durum wheat varieties whose quality, yield and agronomic characteristics are different, were used. These are grown commonly in the Central and Sub-northern regions of Anatolia. Results of the research showed that nitrogen fertilization had some positive effects on semolina yield, and ash and pigment content depending upon the year and location.
