    Objective: To investigate the effect of Seaweed Liquid Fertilizer (SLF) of the red seaweed Hypnea musciformis (Wulfen) Lamouroux (H. musciformis). on the growth, biochemical and pigment characteristics of Arachis hypogea (A. hypogea). Methods: Experiments were conducted on ground nut to study the potential red alga of H. musciformis as a biofertilizer. The seeds were sown in soil and SLF were added to soil bed in five different concentrations separately (1%, 2%, 4%, 6% and 8% w/v). Results: The 2% concentration of water extract showed better results of growth parameters, biochemical and pigments constitutions. Among the different concentrations of SLF investigated, the plants that received with 2% SLF showed maximum germination percentage, fresh weight, dry weight, root and shoot length, number of branches, leaf area, root nodules and content of total chlorophyll, chlorophyll a and b, protein, carbohydrate and lipid were observed at 2% concentration of SLF. The leaf of 2% SLF treated A. hypogea has subjected to Scanning Electron Microscopy with Energy Dispersive spectroscopic analysis, it revealed that the presence of ten elements in the following order: Ca>P>N>Na>K>Mg>Mn>S>Fe>Zn in treated and Ca>N>P>Na>Mg>Mn>K>Zn>S>Fe in control plant. The data generated from study reveal that SLF of H. musciformis could be used as foliar spray at low concentration of 2% to maximize the growth and yield of A. hypogea and also increase the number of stomata in the leaf. Conclusion: It is suggested that there are considerable gains to be made in increasing yield and stabilizing the yield in environments characterized by terminal requirement for organic and by shortening crop duration nutrient management appear promising
