Analysis of the Current Status and Existing Problems of Upland Rice Production
Upland rice, also known as dryland rice, is a type of cultivated rice with strong drought resistance, tolerance to poor soil, and suitability for dryland direct seeding and dryland management. It can be planted in any soil suitable for growing major dryland grain crops such as wheat and corn. It does not require water layer management throughout the entire growth period, and its irrigation volume is only 1/4 to 1/10 that of paddy rice.

Overview of World Upland Rice Production Currently, the world's upland rice planting area is 0.18 billion hectares. In West Africa, upland rice accounts for more than 75% of the rice growing area, and in
