Water Quality Effect on Yield and Yield Components of Four Genotypes of Safflower

The present study was conducted with the aim of investigating the effect of water quality on safflower yield and yield components. The experiment had two factors including water salinity at two levels (S1= 1.8 dS m-1 and S2= 5.8 dS m-1) and landrace genotypes of safflower (G1= Dizaj Hossein Beig- Marand, G2= Koshaksara- Marand, and G3= Agkand- Mianeh). The experiment was laid out as a split plot design with three replications. Results showed that the interaction effects of salinity and landrace genotypes on grain yield, 1000- seeds weights, and the main capitol weight were significant (P
