Present research was carried out with the aim of identifying effect of salt stress (NaCl 0.0, 50, 100, 150 and 200 mM) on growth and physiological parameters of fenugreek (Trigonella foenum-graecum L.) variety RMt-1, a leafy vegetable. Various parameters such as germination percentage, shoot and root length, shoot-root ratio, number of leaves and branches, vigour index, fresh and dry weight, moisture content, relative water content and photosynthetic pigments were analyzed. All the parameters were recorded at 15, 30, 45 and 60 Days After Sowing (DAS). Analysis revealed a significant reduction in all parameters with increased salt concentration. Severity of salinity were also observed with increased age as increase in all growth parameter were non-significant in stressed plant as compared to non-stressed plant. A significant reduction from 100-30% was observed in germination percentage under salt stress. High salt concentration delayed the process of germination. Shoot length and root length was significantly reduced from 38.83 cm (control) to 9.44 cm (200 mM) and from 7.48 cm (control) to 2.44 cm (200 mM) respectively at 60 DAS. This analysis was further supported by fresh and dry weight of shoot and root, shoot/root ratio and moisture content. Present study concluded that the effect of salt toxicity was more prone in shoot as compared to root. The study also signified salt dependent behaviour of different photosynthetic pigments. A positive correlation was observed between stages of growth and reduction in parameters under salt stress. Overall study concluded that fenugreek variety RMt-1 is sensitive towards higher concentration of salts.
