Abstract

The experiment conducted to evaluate the growth of two different genotypes of tomato plants under salt stress. The effect of sodium chloride measured using four different concentrations (0.0M, 0.1M, 0.2M, and 0.3M) in a dose dependent manner. Seedling Height, Number of leave, Leave Area Index, Fresh weight, Dry weight (Biomass), Number of Flowers, Number of Fruits, Weight of Fruits and Maximum height of plant were measured in experiments. Results showed that tomato plants treated with a control group or less salt concentration presented better growth and survive for a longer period as compared to salt dominant groups. The results designates that salinity influences almost every parameter of plant growth, which concludes that salt stress has an antagonistic effect on plant growth.
