Abstract

Black gram is a vital legume crop, but its yield is often limited by factors like nutrient deficiencies, pest and disease pressure, and abiotic stresses. Seaweed extracts may help mitigate these challenges by improving plant resilience and stress tolerance. The black gram was raised in Annamalai University Experimental Farm, Faculty of Agriculture, Annamalai Nagar, Tamil Nadu during February to April, 2021. The experiment consisted of seven treatments viz., 100 % RDF along with seed treatment and foliar application of seaweed extract (Sargassum sp. and Kappaphycus sp.) @ 5%, 10%, and 15% which was laid out in Randomized Block Design with three replications. Seed treatment and foliar application @ 5% seaweed extract (Sargassum sp.) + RDF excelled the other treatment in recording the higher yield, yield attributes viz., number of pods/plant, number of seeds/pod, test weight, seed yield and haulm yield. This research can contribute to developing eco-friendly and cost-effective alternatives to conventional agricultural practices, aligning with sustainable agriculture goals.
