In the current examination, we assessed the impacts of titanium dioxide nanoparticles (TiO2 NPs) for ameliorating salinity in Grass pea (Lathyrus sativusL.), a useful legumes crop. Experimental salinity was controlled in terms of dSm-1at levels of 0 (control), 4, 8 and 12 dSm-1, have been researched in a factorial experiment based on randomized complete block design with three replications. The impacts of four distinctive TiO2 NPs concentrations (0, 20, 40 and 60 mg L-1) were contrasted with deference with plant development and stress reactions. Germination and seedling emergence percentage was fundamentally affected by 12 dSm-1of NaCl. Presentation to NaCl stress essentially decreased length of grass pea seedling organs (root and shoot) comparatively, the substance of proline expanded for the most part in the roots from moderate saltiness conditions. In any case, foliar of nano-TiO2 conquered pernicious impacts of salt pressure and improved the vast majority of these parameters. The best outcomes were found at 20 mg L-1nano-TiO2. Generally, utilization of Tio2 was useful in expanding saltiness resistance in Grass pea seedlingsand their application may incite a reasonable strategy to ensure plants against sodium harmfulness.
