Abstract


Salts lessen germination, delay emergence, and retard seedling growth of linseed (Linum usitatissimum L.). In this research experiment, we designed to find out the effects of (4 dSm-1+ 13.5 (mmol L-1)1/2, 5 dSm-1 + 25 (mmol L-1)1/2 , 5 dSm-1 + 30 (mmol L-1)1/2,10 dSm-1 + 25 (mmol L-1)1/2 and 10 dSm-1 + 30 (mmol L-1)1/2) on biomass yield of linseed to screen against salinity tolerance using biomass yield characteristic. Highest biomass yield (45.53 gpot-1) was attained by 4 dSm-1+ 13.5 (mmol L-1)1/2 treatment. Biomass yield was decreased as well as the toxicity of salts was increased. Lowest biomass yield (27.75 gpot-1) was produced at 10 dSm-1 + 30 (mmol L-1)1/2. 5 dSm-1 + 25 (mmol L-1)1/2 treatment performed better results i.e. the least reduction % over control (20.25). Salinity- sodicity showed serious effect on the growth reduction from 20.25% to39.05%. This reduction gap was affected by the negative effect of salinity and sodicity on Linseed growth.Salinity- sodicity showed severe impact on the growth reduction from 20.25 to39.05%. Based on the findings, linseed (Linum usitatissimum L.) was able to grow the highest at 4 dSm-1+ 13.5 (mmol L-1)1/2 treatment.

Keywords: Linum usitatissimum, saline-sodic, medicinal value and biomass yield
