Abstract
This study was conducted in a randomized complete block design with three replications with aimed to investigate the effects of different levels of salinity stress on root traits, allometric coefficient, and grain yield of Galega in three cultivation conditions (greenhouse, outdoor pots, and field) during 2024 cropping year. The results of variance analysis in greenhouse conditions showed that salinity stress had a significant effect on root diameter, root dry weight, and leaf dry weight. Specifically, salinity stress of 10 and 5 dS/m caused a 49 and 16 percent reduction in root diameter, 27 and 8 percent in root dry weight, and 49 and 10 percent in leaf dry weight, respectively. In outdoor pots, salinity stress had a significant effect on stem length, root volume, root diameter, root dry weight, stem dry weight and grain yield, and significant reductions were observed in these traits, reaching a maximum of 69% in stem dry weight. In field conditions, similar results were obtained, and salinity stress of 10 and 5 dS/m, respectively, caused a 78 and 67% reduction in grain yield and significant changes in other traits. Therefore, field cultivation conditions and lower salinity stress levels (below 5 dS/m) were superior for planting Galega.
