Title : Effect of soil salinity on germination and survival of tomato (Solanum lycopersicum L.)

Abstract :

The study was conducted at the Vegetable Research Farm, Department of Vegetable Science, Punjab Agricultural University, Ludhiana to study the effect of soil salinity on germination and survival of tomato. The 2 dS/m, 4 dS/m, and 6 dS/m levels of salinity were induced by using sodium chloride, magnesium sulphate and calcium chloride in ratio 2:1:1. Seeds from 155 tomato genotypes were sown in plug trays, with each genotype having two sets of trays. For one set, normal water (tab) was used initially, and then saline water was applied after the seedlings reached the two-leaf stage (10-12 days after sowing). For the second set, saline water was applied immediately after sowing to evaluate germination under salt stress. The results categorized the genotypes into 18 tolerant, 92 semi-tolerant, and 45 susceptible to salinity based on nursery and morphological screening trials. Among the 18 tolerant genotypes, PTNI-203, PTNI-202, and PTNI-8 were suggested for further research in salt-affected areas.
