The aim of the present study was to investigate the effect of amendment of fish waste as an organic fertilizer to enhance the growth and nutritive value of Amaranthus campestris. The experiment on Amaranthus campestris was conducted with and without the addition of fish waste water as a fertilizer to examine the plant's growth, nutritional status and chemical composition of soil. There are various minerals, proteins, carbohydrates, and moisture are found in marine waste, which offer nutrients to the soil that helps the plants to grow healthier. The fish waste was collected at a local market, washed properly, mixed with jaggery, banana and water, allowed to ferment for 15 days and then sprinkled to one pot labelled as 'Test' and another pot without fish waste water amendment labelled as 'Control', the plant growth in the following weeks noted and the mineral content in both plants and soil were analysed. The number of seeds germinated, plant height, root length, mineral content in soil and leaves, were all higher in the pot labelled 'Test' when compared to the pot labelled ‘Control’. The results showed that adding fish waste water fertilizer to soil improves mineral quality of soil and makes plants healthier, and acts as the greatest organic fertilizer. As a result of the findings of this study, it may be concluded that fish waste water is an effective organic fertilizer for improving soil quality, plant growth and the nutritional status of the plant.
