Abstract: The products of seaweed liquid extracts (SLE) are receiving intense attention as bio-stimulant in integrated crop nutritional applications. In the present study, the effect of the SLE of brown seaweed Turbinaria conoides was evaluated at different concentrations (control, 5, 10, 15, 20 and 25%) on germination and growth parameters (root length, shoot length, total fresh weight and total dry weight) of Arachis hypogaea. Liquid extract of T. conoides was found effective in stimulating germination and growth of the plant in the low concentration. This investigation has revealed that the low-level concentration of SLE (5%) has been enhanced the germination and growth parameters of the test plant than control and maximum seed germination (100%) of A. hypogaea was achieved in 5% concentration. The highest shoot length (4.62cm), root length (2.42cm), fresh weight (1.82g) and dry weight (0.88g) were recorded in the plants which treated with concentration of SLE. Highest (25%) concentration of SLE has been stunt the growth germination of the test plant.
