Researchers used papaya fruit peels to make organic fertilizer through a special process. When this fertilizer was used on maize plants, it made them grow better than regular chemical fertilizer or no fertilizer at all. The organic fertilizer helped the plants grow more leaves, taller, and with bigger roots. It also increased the amount of important nutrients in the plants and soil. This shows that using organic fertilizer made from fruit peels can be a good way to improve crop growth without relying too much on chemical fertilizers.
