Salinity and sodicity disturbs growth of medicinal crop Guar (Cyanoposisa tetragonoloba)

Salinity is one of the major and increasing problems in irrigated agriculture in Pakistan. Salinity stress negatively affects the growth and yield of plants guar (Cyanoposisa tetragonoloba). 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 (54.50 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 salts toxicity. Minimum biomass yield (30.17 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 (18.66). Salinity cum sodicity showed staid effect on the growth reduction from 18.66% to 44.64%. This reduction fissure was impacted by the toxic effect of salinity and sodicity on Guar growth. Salinity- sodicity behaved toxic impact on the growth reduction from 18.66% to 44.64%. Based on the findings, guar (Cyanoposisa tetragonoloba) grows better at 4 dSm -1 + 13.5 (mmol L -1 ) 1/2 treatment.
