ABSTRACT The aim of the present study was to investigate the effect of amendement of crabshell powder as an organic fertilizer to enhance the growth and nutritive value of Raddish. OBJECTIVE: The experiment on Rhaphanus sativus was conducted with and without the addition of crab shell powder as an organic fertilizer to examine the plant's growth, nutritional status and chemical composition of soil. METHODS : Minerals, proteins, carbohydrates, and moisture are found in marine waste, which offer nutrients to the soil that helps to grow plants more healthier. The crab shell was collected at a local market, washed properly, dried in the sun for a few days, powdered, and then added to one pot labelled 'Test' and another pot without crab shell amendment labelled 'Control', the plant growth in the following weeks noted and the mineral content in both plants, tubers and soil were analyzed. RESULTS: The number of seeds germination, plant height, minerals content in soil, leaves, and tubers were all higher in the crab shell amendment pot labelled 'Test' when compared to the pot without crab shell amendment labelled ‘Control’. The results showed that adding crab shell powder to soil improves mineral quality of soil and makes plants healthier, and acts as the greatest organic fertilizer. CONCLUSION: As a result of the findings of this study, it may be concluded that crab shell is an effective organic fertilizer for improving soil quality, plant growth and mineral quality.
