The present study showed that percent germination, radicle and plumule lengths of Brassica juncea were adversely affected by increasing the level of salinity. As compared to 95 per cent germination of the control, there were 92.50. 90.00, 90.00, 85.00, 87.50 and 80.00 per cent germination respectively at 2.5, 5.0, 7.5, 10.0, 12.5 and 15.0 dSm-1 NaCl salinity levels. Similarly, all the parameters tested in the pot experiments showed gradual decline with the corresponding increasing levels of NaCl salinity. At lower levels of salinity (2.5 and 5.0 dSm-1), Brassica juncea had reasonably good growth and productivity. It showed greatly reduced growth and at 7.5 and 10.0 dSm-1 while at 12.5 and 15.0 10.0 dSm-1 salinity levels it was severely production affected. It is concluded from the present work that Brassica juncea can be grown fairly on mild saline soils for a food, fodder and seed production.
