  • Descrição: •The waste leaves of polyalthia longifolia synthesized highly stable magnetite (Fe3O4) nanoparticles with size ranging from 19 to 21 nm.•50 mg/L NPs concentration was found most effective for plant growth and development under control and drought stress condition.•Photosynthetic pigments, ETR and yield were enhanced in both drought tolerant (Afg 1) and drought sensitive (Afg 3) varieties of trigonella foenum-graecum. Nanoparticle (NPs) biosynthesis is gaining popularity due to its low cost and environmental benefits. The objective of current study was to biosynthesize magnetite (Fe3O4) NPs using leaves of Polyalthia longifolia. Biomaterials present in the leaves of Polyalthia longifolia synthesized Fe3O4 NPs by reducing the iron precursor salt (FeSO4•7H2O) and also acted as capping and stabilising agents. The characterization confirmed synthesis of cubical shaped Fe3O4 NPs with size ranging from 19 to 21 nm. Two varieties of Trigonella foenum-graecum (Afg 1 and Afg 3) were used to study plant growth parameters, photosynthetic pigments and photosynthetic performance under control and drought stress condition with various concentrations of Fe3O4 NPs (20, 50, 100 and 200 mg/L). The test parameters varied as the dose of exogenous foliar concentration of Fe3O4 NPs increased. Afg 1 (drought tolerant) and Afg 3 (drought sensitive) both showed most effective response at 50 mg/L NPs concentration in alleviating drought stress. [Display omitted]
