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 ago-chemical. Women cultivate small fields of rainfed lowland rice (from few hundred to few thousand square meters). A number of improved rice varieties have been released for cultivation.

Land preparation for lowland rice is done either manually or with animal traction. Transplanting is the main method of crop establishment. Farmers generally apply little fertilizer to rainfed lowland and tidal wetland (or mangrove) rice. Weeding is generally done manually and farmers do not have adequate appropriate tools and equipment for harvesting and threshing of rice. Studies showed positive responses of rainfed lowland rice to phosphorus fertilizer application.

Constraints and Issues of Sustainable Production

There are several constraints to sustainable rice production in Guinea. Following are the majors:

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