Influence of Seaweed Extracts on Growth and Seed Yield in Green Gram (Vigna radiata L.) cv. VBN 2

With the aim to assess the effectiveness of seaweed extracts, specifically Kappaphycus alvarezii and Gracilaria, on seed yield in green gram (Vigna radiata L.) cv. VBN 2. The Department of Genetics and Plant Breeding at Annamalai University's Experimental Farm served as the site for the field trial. The results revealed that seeds soaked with Kappaphycus alvarezii (2.5%) exhibited higher value for the growth attributes, physiological traits, pod characters and seed yield attributes of green gram VBN 2. It also recorded days to first flowering in earlier days. The results of the present investigation suggest that in order to enhance growth and yield characteristics under difficult environmental conditions, green gram seeds should be treated with 2.5% Kappaphycus alvarezii seaweed extract for 12 hours.
