In the frame work of the rice production intensification by IFDC
project in Ruzizi plain in the Sud Kivu province, DR Congo,
The Catholic University of Bukavu (UCB) and Evangelical
University in Africa (UEA) are collaborating in research to
develop high yielding irrigated rice varieties in Ruzizi plain. This
is necessary in order to increase rice production to substitute
importation of malt. Increasing rice production in Ruzizi plain
will also contribute to food security and poverty alleviation for
farmers. Trials were carried out in a randomised block design
with 3 replications in 4 irrigated rice areas, i.e., Luvungi, Luberizi,
Sange and Kiringye. Twenty four introduced varieties and 3
local varieties were evaluated. Two varieties among the 24
introductions yielded up to 8 tons per ha while five yielded up to
7 tons per ha. The local varieties yielded 2.5 tons per ha or
less. The highest yield was recorded from Luberizi. The
introduction; RW 17, RW 5, RW 9, RW 13 and V 27 yielded
between 7.5 and 8 tons per ha. These varieties have low spikelet
sterility and can thus be recommended to farmers. Fertilisation
trials are also under way to assess potential of these lines for
breeding purposes.
