Dear @Parmeshwar Lal Saran I would suggest to:
1. Select crops or crop cultivars that can grow successfully under saline conditions. Among the highly tolerant vegetables are beets, kale, asparagus, spinach and tomato,
2. Use land preparation and tillage methods that aid in the control of salinity.
3. Pre-emergence watering in special furrows placed close to the seed often is done to reduce the soluble salt concentration around the seeds to permit germination,
4.Use special planting procedures that minimize salt accumulation around the seed. Unlike single row beds, with double-row beds, most of the salt is carried into the center of the bed, leaving the shoulders relatively free of salt and satisfactory for planting.
5. Apply special treatments, such as, adding organic matters to improve and maintain good physical condition of the soil.
Please also check the following link, and attachment; hope, these could be useful.

We should always keep a vigil that pH and EC are correlated within certain limits only , depending upon composition of saline water used for such purpose . Usually pH is more related to sodium adsorption ratio and residual sodium carbonate. So , lets identify your prime objective , which one would you prefer , either of the two against vegetables...The impact is often goverend by texture and mineralogy of the soil , though you are using saline irrigatiin water , since there will be greater magnitude of impact of saline irrigation on clay soils than sandy or loam soils....
For vegetable cultivation, prevailing climatic and weather conditions are also critical.
