Abstract

The present study deals with the investigation of the effect of Seaweed Liquid Fertilizer (SLF) of the red seaweed Gracilaria dura (Ag.) J.Ag. on the growth, biochemical and pigment characteristics of Vigna radiata (L.) R. Wilczek., in Hare island, Thoothukudi, Tamil Nadu, India. The seaweed liquid fertilizer (SLF) obtained from Gracilaria dura (Ag.) J.Ag was treated in different concentration such as 2.5, 5.0, 7.5 and 10.0% and tested on Vigna radiata (L.) R. Wilczek. Among the different concentration of SLF investigated, plants that received 10% Seaweed Liquid Fertilizer showed maximum content of total carbohydrates, total proteins, total lipids, total phenols, total chlorophylls and total carotenoides compared to other concentrations. From the results obtained, it was suggested that there are considerable gain to be made increasing yield and stabilizing yield requirements for organic nutrient management appear promising.
