Abstract

Salt stress is one of the most serious limiting factors for crop growth and production. Salinity stress negatively impacts the growth and yield of plants. Niazboo (Ocimum basilicum). This experiment was conducted to evaluate 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 guar against salinity tolerance. Maximum biomass yield (43.10 gpot -1 ) was produced by 4 dSm -1 + 13.5 (mmol L -1 ) 1/2 treatment. Biomass produce was reduced with the increase of the salt's toxicity. Minimum biomass yield (30.33 gpot -1 ) was attained under 10 dSm -1 + 30 (mmol L -1 ) 1/2 . 5 dSm -1 + 25 (mmol L -1 ) 1/2 treatment exhibited improved outcome i.e. the least diminution % over control (11.83). Salinity cum sodicity showed staid effect on the growth reduction from 11.83% to 29.62%. This reduction fissure was impacted by the toxic effect of salinity and sodicity on Guar growth. Salinitysodicity behaved toxic impact on the growth reduction from 11.83% to 29.62%. Based on the findings, Niazboo (Ocimum basilicum) establishes better at 4 dSm -1 + 13.5 (mmol L -1 ) 1/2 treatment.
