Özet

This study was conducted to investigate the relationship between chlorophyll values of the CM 1000 FieldScout and nitrogen use efficiency, grain yield of some durum wheat cultivars grown in different nitrogen conditions. The research was set up in four replications according to the split plot design in the conditions of Diyarbakir during the growing season of 2017-2018. In this study, stem elongation stage, heading stage, anthesis stage, 10 days after anthesis and 20 days after anthesis Chlorophyll measurement, nitrogen use efficiency and grain yield were investigated. As a result of the study, the highest nitrogen use efficiency was obtained at 0 kg/da (N0) nitrogen application. Significant relationships were determined between the values measured with CM 1000 chlorophyll meter and nitrogen use efficiency and grain yield in N0 nitrogen application, stem elongation, heading and flowering stage in terms of grain yield and nitrogen use efficiency. In nitrogen application at 15 kg/da (N3), significant correlations were found between the values measured with CM 1000 chlorophyll meter and grain yield and nitrogen use efficiency during the heading stage. Especially at low nitrogen doses. It was concluded that it would be appropriate to use the CM 1000 chlorophyll meter to determine the nitrogen use efficiency and grain yield.
