Background and Objectives: The production of forage from environmental stresses adaptable plants, such as safflower (Carthamus tinctorius L.), can be considered as an effective strategy for forage supply in climate change conditions. The study was conducted to evaluate the quantitative and qualitative forage performance of safflower genotypes in saline and marginal areas.
Materials and Methods: The experiment was conducted in 2024 using a randomized complete block design with three replications in East Azerbaijan Agricultural and Natural Resources Research and Education Center. The eleven promising forage safflower genotypes were used to evaluate their forage yield and qualitative characteristics in marginal areas around Urmia Lake.
Results: The results of research indicated that genotypes PI237550, PI305169, and PI407614 had the highest dry forage yield with 9000, 8278, and 8180 kg ha-1, respectively. The lowest dry forage yield was observed in genotype PI237539 with 3611 kg ha-1. The genotypes PI239706 and Golemehr recorded the highest amounts in ash and crude protein, respectively. The yields of protein in PI305169, PI407614, PI407605, Golemehr, and PI237550 were higher than others. Positive and significant correlations between the fresh and dry forage yields with each other and with qualitative characters including crude protein and protein yield, were obtained.
Conclusion: The studied genotypes indicated acceptable forage yields during three- month growth periods. The genotypes PI237550, PI305169, and PI407614 showed the highest fresh and crude forage yields, and with higher total protein, can be suitable for forage production as spring cultivation in the saline and marginal areas around Urmia Lake.
