Marine algae (Seaweeds) Seaweed Hypnea sp (species) are often regarded as an underutilised bio-resource seaweed have been used as organic materials due to the presence of a number of plant growth stimulating compounds. The effect of various seaweed species on plant growth and development with an emphasis on the use of this renewable bio-resource in sustainable agricultural northern fertiliser raw materials system. A plant needs organic fertiliser for it to grow in a balanced way. The combined use of organic and inorganic fertilisers can improve crop production and maintain soil health. Many important soil properties depend on to some degree on the quality of organic matter. Organically made fertilisers play an important role in increasing the crop yield and the quality of crops promises improvements considering climate adaptation. Research on marine products has enormous unexploited potential and significant advantages. Although Bangladesh possesses a part of the Bay of Bengal, the vast ground of our marine resources is yet to be explored and the application of biotechnology to marine biodiversity remains poorly developed. Therefore, a systematic and comprehensive study is essential. The proposed one year pilot project will be started collecting samples from the Bay of Bengal. The plants will be preliminarily characterised based on morphological and phenotypic characteristics. To identify the possible usefulness of these plants in food, health and pharmaceutical industry, the amounts and ranges of carbon, phosphorus, nitrogen, mineral contents, vitamins and proteins will be analyzed. Marine algae or seaweeds are traditional Asian foods particularly common in Japan and Korea. It is consumed as a snack or as ingredients in dishes or soups.
