A field experiment was conducted to assess the impact of combined application of seed dressing and foliar administration of sea weed on growth attributes of black gram. The crop was raised in Annamalai University Experimental Farm, Faculty of Agriculture, Annamalai nagar. The experiment consisted of seven treatments and was laid out in Randomized Block Design with three replications. Seed treatment and foliar application @ 5% seaweed extract (Sargassum sp.) + RDF excelled the other treatments in recording the highest growth attributes viz., plant height, LAI, DMP and number of branches per plant. The diverse mix of micro and macro nutrients, trace elements, humic acid, amino acids, plant growth hormones, vitamins, antibiotics, and organic matter in seaweed extract significantly enhanced black gram’s growth parameters like plant height, leaf area, and root biomass.
