Water scarcity is reducing both irrigated areas and irrigated rice yield in the South-Kivu
province, DR Congo, leading to increased poverty and food insecurity, at both provincial and
national level. This situation is likely to be worsened by climate change and population
growth. A study was conducted with the major aimof assessing the effect of water saving
technologies (WST) on rice yield. A split plot experiment 5 varieties (3 imported and 2
local)was set up with 3 WST, namely alternating wetting and drying and saturated soil
without flooding and the permanent flooding. The experiment was conducted in both lowland
(Luberizi) and highland (Kavumu) of South-Kivu. Results showed that WST did not affect
significantly the biomass both in sites (p>0.05). Varieties, however, impacted significantly
the biomass, but only in Lowlands (p=0.001). In Lowlands, WST affected significantly rice
yield (p=0.05) but it did not in Highlands (p>0.05). Rice yield varied significantly from one
variety to another both in Lowlands (p<0.001) and in Highlands (p<0.001).
