Abstract Growth and development of safflower (Carthamus tinctorius) are influenced by many factors such as genotype, environmental conditions, and agronomic practices. One of the most important agronomic pratices is fertilization. As a fertilizer, Nitrogen is an essential element required for successful plant growth. In the study, it was aimed to determine the effects of different nitrogen rates (N1= 0, N2= 100, N= 150, and N4= 200 kg N ha−1) on yield and yield components of three safflower varieties (Remzibey-05, Dinçer and Yenice) under micro-climate conditions in Agricultural Research Fields of Iğdır University, Iğdır, Turkey during 2012 – 2013 according to the split plot on the basis of randomized block design with three replications. The investigation indicated that the differences among the varieties were found significant for all attributes except seed number per head and seed oil content. And also, the the effect of differences between observation years and the effects of nitrogen rates were determined to be significant for all observed properties.
