Salinity is the major abiotic factor that reduced the plant germination percentage, growth and productivity. However, micronutrients have an important role to reduce the salt stress effectively. This study was conducted to investigate the role of Fe via seed priming of Vigna radiata L. with two concentrations (100ppm & 200ppm) of FeSO₄ and grown under various levels (0-50-75-100mM) of NaCl. The results showed that NaCl stress reduced the germination percentage of Vigna radiata but seed priming with FeSO₄ improves the germination percentage. The seed priming with 100ppm showed maximum values of germination percentage (96.66±0.23), shoot length (37.84±0.08 cm), shoot fresh weight (26.87±0.067) and dry weight (9.05±0.08), root length (23.27±0.020), fresh weight of root (5.17±0.031), root dry weight (2.48±0.06), Proline (65.30±0.24) were observed. While 200ppm showed significantly maximum values of chlorophyll a& b contents, total soluble protein (0.372±0.18), Phenolic contents (95.57±0.12), and flavonoids (84.26±0.17). Seed priming with FeSO₄ has significant effects on the Vigna radiata L. under NaCl stress and improves the germination, growth, and biochemical parameters.
