The Effect of Different Concentrations of Some Nanoparticles and Seaweed Extract on the Vegetative Growth of Rosmary [ Salvia Rosmarinus L.] Plant

Abstract

The presented study to investigate the response of rosmary (Salvia rosmarinus L .) plants on the influence of nanoparticles (zinc and magnesium) and seaweed extract carried out in 2024 on fields in wasit university , College of Sciences , Iraq. The treatment construction was a perfectly randomized factorial experiment (5×5×3) in completely randomized design , done with three replications . The rosemary plants treated with nanoparticles (zinc oxide) with concentrations (0, 0.03 , 0.05) mg/ml and (magnesium oxide ) with concentrations (0, 0.02 , 0.04 ) mg/ml and rosmary treated with seaweed extract with concentrations (0, 50 , 100 , 150 , 200 )gm/L.Studing plant height (cm) , total chlorophyll (µmol m-2) , percentage of dry matter (%) , leaf surface area (cm2.plant-1) , nitrogen (%) , phosphorus (%) and potassium  percentage .Based on results , adding nano zinc and nano magnesium and seaweed extract to the rosemary plant significantly increased all triats , regardless of vegetable characteristics or chemical content achieved wih highest concentrations   using  highest effects whether alone or with two interactions .
