Abstract: Salinity is one of the most abiotic factors which adversely affected the crop yield due to limits the growth and production of crop in arid and semi - arid regions in the world. Seedling establishment is a most critical stage that determined the crop production at later stages, thus it must necessity to study the effect of salt stress on germination and early seedling parameters. Present investigation aimed to assess the effect of salt stress on germination and early seedling parameters of fenugreek. Fenugreek (Trigonella foenum-graecum L.) is a winter season seed spices crop, commonly known as Methi and moderately tolerant to salinity. We took ten genotypes of fenugreek grown under five salinity levels viz., 0.0, 40, 80, 120 and 160 mM NaCl salinity induced by supplementing 0.0, 584.4, 1168.8, 1753.2 and 2337.6 mg NaCl in 250 ml double distilled water, respectively. Results showed that the mean value was found maximum in the control and minimum at higher salinity level for most of characters. Higher reduction was found at higher salinity levels for most of the characters viz., plumule length, radicle length, seedling length, plumule to radicle length ratio, plumule fresh weight, radicle fresh weight, plumule dry weight, radicle dry weight and seedling vigour index but lower reduction in germination percentage. Based upon the rank totals of a genotype over different salinity levels S1, S2, S3 and S4 (Sm) and characters, the genotype RMt-303 was found to be most desirable followed by UM-385, RMt-143 and RMt-305. The comparison between mean of different genotypes in control (S0) versus Sm (mean of S1, S2, S3 and S4) for each character also revealed that overall mean was highest in control as compared to the overall mean of salinity levels for all the characters.
