Production Practices
Rice is planted only under irrigated conditions. Land preparation for lowland rice is done either mechanically or with animal traction. Both transplanting and direct seeding are used for crop establishment. Farmers generally apply moderate to high rates of inorganic fertilizers. Weeding is generally done manually, although the use of herbicides is increasing in irrigated rice. Farmers do not have adequate appropriate tools and equipment for harvesting and threshing of rice. A number of rice varieties have been released for cultivation.

Constraints and Issues of Sustainable Production
There are several constraints to sustainable rice production in Mauritania. Following are the majors:
Low temperature during off-season in irrigated areas
Shortage of water in the dry season
Low P content in rice soils
Poor maintenance of irrigation facilities
Poor drainage in irrigated schemes
High production costs
Inadequate and Irregular input supplies: seeds, fertilizer and credit
Lack of small farm equipment, especially for post harvest operations
Lack of effective farmer organization and co-operative
Competition of labour by other production activities
Lack of a well-defined rice policy
Poor road networks and marketing systems
Weak research and extension support
Sustainable rice production depends greatly on appropriate policy to provide farmers with support in inputs supply and marketing of products.
