<p>Salinity stress poses a significant threat to crop productivity, particularly in coastal regions such as the Sundarbans Delta in India. This study investigates the role of arbuscular mycorrhizal fungi (AMF), specifically <i>Glomus mosseae</i>, in mitigating salinity-induced stress in chickpea (<i>Cicer arietinum</i> L.). Six high-yielding desi-type chickpea lines, including one tolerant (Digbijoy), three moderately susceptible (IC 268971, Radhey, Mahamaya 1), and two highly susceptible (Virat, DCP 93-3), were selected for evaluation under controlled greenhouse and field conditions. Salinity stress was induced at 300&#xa0;mM NaCl in pot experiments, while field trials were conducted in naturally saline soil. Results indicated that salinity significantly reduced key agro-morphological parameters, including seedling length, nodules plant⁻¹, leaf area index, plant height, branches, pods plant⁻¹, pod length, seeds pod⁻¹, 100-seed weight, and seed yield plant⁻¹. However, AMF inoculation mitigated these adverse effects, improving seedling emergence by 45%, plant height by 52%, pod number by 95%, and seed yield by 48% in field conditions. Additionally, AMF inoculation under salinity increased spore population by 535% and structural colonization (mycelium by 181% and arbuscules by 204%). Biochemical traits such as total phenolic content, relative water content, membrane stability index, and chlorophyll levels improved significantly in AMF-treated plants compared to those under saline conditions alone. The observed improvements ultimately led to a notable enhancement in grain yield, demonstrating the efficacy of <i>Glomus mosseae</i> in alleviating the adverse effects of salinity stress in chickpea. These results emphasize the role of arbuscular mycorrhizal fungi (AMF) as a viable, environmentally friendly solution to boost chickpea production under saline conditions, presenting a valuable tool for promoting climate-resilient farming in salt-affected areas.</p>
