Rice ratooning can help produce a second crop from the stubble after the main crop is harvested. Factors like choosing the right rice variety, managing water and fertilizer, and maintaining the right stubble height can affect the yield of both main and ratoon rice. It's important to pick varieties that resist pests and diseases, provide enough water and fertilizer, and keep the stubble at a height of 10-20 cm. Extreme temperatures and light can lower rice yield and quality, so it's best to have optimal conditions. By improving management practices, the yield of both main and ratoon rice can be increased. More research is needed to enhance the quality of ratoon rice.
