Abstract: Soil salinity is a global problem, which is predicted to worsen in arid and semi-arid regions due to climate change. The aim of this study was to understand the remediation potential of different growing conditions (plain bed, ridge bed, polyethylene mulch and water hyacinth mulch) and organic amendments (no manuring, cowdung, vermicompost and poulty manure) in alleviating salt stress by studying its effects on the growth and yield parameters of the tomato. The experiment was arranged in a Randomized complete block design with three replications. Among the growing conditions, the highest plant height (148.67 cm), number of fruits/cluster (7.73), yield (4.45 kg/plant and 95.73 t/ha) were observed in polyethylene mulch. In the case of organic manures, the highest plant height (127.32 cm), number of fruits/cluster (6.59), and yield (3.70 kg/plant and 79.84 t/ha) were observed in vermicompost treatment. Furthermore, the highest plant height (153.10 cm), number of clusters/plant (16.13), number of fruits/cluster (8.06), and yield (4.83 kg/plant and 103.88 t/ha) were observed in the interaction of GC3×OM3. The benefit-cost ratio (BCR) was highest (2.48) in the interaction of polyethylend mulch with vermicompost. Therefore, it can be concluded that the treatment interaction of polythene mulch with vermicompost exhibited great potential for better growth and yield of tomato under saline stress conditions.
