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 almost without any application of chemical fertilizer and other agro-chemical. In rainfed lowland and irrigated rice production, land preparation is done by varying methods from manual land preparation using only hand hoe to land preparation with either animal traction or with tractors, depending on the farm size and available means. Transplanting is the popular method of crop establishment. Farmers generally apply little fertilizer to rainfed lowland, but moderate to high rates of inorganic fertilizers may be applied to irrigated rice. Information on rice response to fertilizer application, however, is limited. 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 Tanzania. Following are the majors:
Drought in upland areas and drought and flash flood in rainfed lowland (or inland swamp) areas due to irregular weather
Infestation of red rice in the irrigated schemes
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
Poor maintenance of irrigation facilities
Lack of a well-defined rice policy
Poor road networks and marketing systems
Labour shortage due to competition from other crop
Weak research and extension support
Sustainable rice production would greatly depend on the establishment of appropriate policy to provide support to farmers especially in-terms of input supply and output marketing. The development of lowland rice production with improved water supply and control would be essential.
