• Salinity is a major factor limiting irrigated agriculture in arid regions. Vermi amendments can be used for improving the fertility of salt-affected soils. Current study was aimed to find out the response of different earthworm species to soil salinity and to check the effects of salinity and different vermi amendments on growth of Sorghum bicolor under salt stress. Eight earthworm species were subjected to different salinity levels for 4 weeks. Various vermi amendments and salinity treatments were provided in a factorial combination to S. bicolor plants to see their effect on growth and biomass parameters. L. mauritii, E. incommodus and P. posthuma were found to be the most salt-tolerant species showing good survival and growth till soil EC ₑ value of 10.48 mS cm ⁻¹. Results showed that salinity significantly decreased plant growth that was enhanced by the application of different vermi amendments. Maximum growth of S. bicolor was recorded when vermicompost and vermiwash were used together under both saline and non-saline conditions. The results showed that the application of vermi amendments improved nutritional balance of the soil, delayed salt-induced damage to the plants and supported their growth so can be helpful in increasing crop production on saline soils.
