Another kind probably grew in West Africa. Other scientists think that rice came from India, and Indian travelers took it to other parts of the world. There are two main ways to grow rice. Most rice grows in wet soil. People in many countries do all of the work of growing rice by hand. This is the same way farmers worked hundreds of years ago.
