Abstract

In order to study salinity stress on four vegetable crops including radish (Raphanus sativus L.), cabbage (Brassica oleracea capitata L.), mustard (Brassica juncea) and water spinach (Ipomoea aquatica), a laboratory experiment as completely randomized design was conducted with three replications in the Department of Soil Science, University of Chittagong, Bangladesh. To create salinity stress, sodium chloride (NaCl) at five levels of 0 (as control), 2, 4, 8 and 16 dS m-1 were used. In the present study, indices such as germination percentage, germination rate, reduction of germination percentage, seed viability index, seedling and root length, seedling and root fresh weight of four vegetable crops were measured. Statistical results revealed that the effect of salt levels on investigated parameters was significant (P< 0.01)). Means comparison for these parameters showed that the application of 8 and 16 dS m-1 salinity resulted in the loss of germination percentage, germination rate, seed viability index, seedling and root length, seedling and root fresh weight of four vegetable crops, as compared to control treatment (0 ds m-1 salinity). In total, it can be concluded that salinity stress significantly decreased germination and growth parameters of seedlings of four vegetable crops.
