Abstract
A biofertilizer means use of living organisms to continuously supply nutrients to the soil. It maintains the natural habitat of the soil. Biofertilizers are cost-effective compared to chemical fertilizers. It was prepared from fish waste (prawn and crab shell).The shells were removed from the meat part and properly cleaned with water and dried and was grind to make it to powdery form for easy use. Later different experiment on pea, gram and tomato plants was carried out in different ratios of prawn, crab and prawn+crab mixtures to see the growth and anatomy of the plant. Neem powder along with the fish waste was applied to the soil to keep the worm away. The fish waste contained minerals, proteins, carbohydrates and moisture which provides nutrient to the soil. The results obtained were compared and found that growth of plants in crabs were faster, greener, healthier and worm free as compared to prawn bio fertilizers. When again it was compared to the control plants with and without neem it was found that the growth was fast in the crab fertilizer and it was worm free.
