The timing of rice harvest varies depending on the location and climate, as well as the specific type of rice being grown. In general, rice is harvested when the grains have reached their maximum size and have turned from green to golden or light brown in color. This usually occurs between 110 and 150 days after planting, depending on the variety of rice and growing conditions. In many regions, the rice is harvested in the fall, typically between September and November. However, in some parts of the world, rice can be harvested year-round.
