Production Practices
The following figure shows the harvested areas from different ecologies during the last five years.
Upland rice is grown as a mono-crop or as in a mixture with other food crops following the slash-and-burn shifting cultivation and rainfed lowland rice is cultivated following traditional systems almost without any application of chemical fertilizer and other ago-chemical. In irrigated areas, support for farmers with regard to input supply has been greatly reduced. Land preparation in rainfed lowland areas is done mostly manually, while that in irrigated areas animal traction has been introduced. Transplanting is the dominant method of crop establishment in lowland systems. Weeding is generally done manually. Farmers do not have appropriate tools and equipment for harvesting and threshing of rice. A number of improved rice varieties have been released for cultivation.

Constraints and Issues of Sustainable Production
There are several constraints to sustainable rice production in Chad. Following are the majors:
Low temperature during off-season in irrigated areas.
Recurrent drought and flood in rainfed lowland areas.
Lack of input supplies: improved seeds, fertilizer and credit.
Lack of small farm equipment especially for post harvest operations.
Lack of effective farmer organization and co-operative.
Poor maintenance of irrigation facilities.
Poor road networks and marketing systems.
Weak research and extension support.
The following table shows the rice production costs.

Sustainable rice production depends greatly on appropriate policy to provide farmers with support in inputs supply and marketing of products. The improvement of water supply and control in rice production is essential.
