The extension requires careful irrigation, fertilization and weed control to achieve high yields.

Economic importance

This includes climate change, which can lead to changed growth conditions and increasing pest and illness problems. In addition, the loss of acreage due to urbanization and the deterioration of the soil quality could affect the harvest yields and restrict the availability of rice for human nutrition.
