ABSTRACT
Cowpea (Vigna sinensis (L) Savi exhassj.), is used as a fodder vegetable, pulse and a green manure crop. It is grown all over India, more particularly in the central and peninsular regions, though on a limited area. It has considerable promise as an alternative pulse crop in dry land forming. An experiment was conducted to study the seedling growth of cowpea in distilled water and in various saline solutions of sodium chloride and calcium chloride concentration (1000, 3000 and 5000 ppm) after 96 h of sowing. The root, shoot and total seedling length decreased significantly at salinity levels of both the salts. The fresh and dry weight also decreased with increase in salinity levels of both the salts.
