Rice seedlings are young plants that grow from rice seeds. They are typically small, green, and delicate, emerging after the seeds are planted in flooded fields or nurseries. These seedlings are crucial for the growth of the rice crop, as they develop roots and leaves that will eventually support the plant as it matures. After about 20 to 30 days, the seedlings are ready for transplanting into the main rice field. This process helps ensure that the plants have enough space and nutrients to grow effectively. Proper care during this stage is essential for a healthy rice harvest later on.
