Overview

Controlled trial demonstrates that combined Rhizobium and seaweed extract alleviate salt stress and boost yield in pea plants, indicating a sustainable strategy for abiotic stress resilience.

Key Points

  • To evaluate the combined efficacy of Rhizobium leguminosarum inoculation and Ascophyllum nodosum seaweed extract on mitigating salt-induced phytotoxicity in vitro and enhancing growth, yield, and quality in field conditions.
  • Assessed in-vitro salinity responses using five treatments: Control, NaCl (100 mM), NaCl + Rhizobium leguminosarum (RZ), NaCl + seaweed extract (SWE, Ascophyllum nodosum), and NaCl + RZ + SWE.
  • Conducted field trials during the 2023–24 rabi season evaluating two pea cultivars (Punjab-89 and Arkel) under Control, NPK recommended dose of fertilizer (RDF), RDF + RZ, RDF + SWE, and RDF + RZ + SWE treatments.
  • Salinity exposure (100 mM NaCl) reduced germination, photosynthetic pigments, and protein levels while triggering membrane lipid peroxidation, proline accumulation, superoxide anions, and hydrogen peroxide.
  • Combined application of RZ and SWE alleviated salt-induced oxidative stress, restored physiological parameters, and improved in-situ growth, yield, and crop quality, with Punjab-89 consistently outperforming Arkel.
