This study assessing the adoption of three varieties of rice altitude marshes come from the Agricultural Research Center / RUBONA of Rwanda to the soil and climatic conditions of eastern DR Congo, specifically NSRF / Lwiro in Kabare territory in South Kivu. Furthermore, we observed that the rooting of these four varieties length corresponded to that determined by several authors, the longest being that of the control variety (Vo46) followed by the variety FACAGRO 56. This confirmed that soil of eastern DRC is of good structure and texture and is well ventilated; which facilitates root development and mineral nutrition. Variety FACAGRO 908 is placed in first position with respect to the number of productive tillers. This depends on factors like good spacing, early weeding, soil fertility and favorable genetic heritage. As regards the weight of 1000 grains, and Vo46 varieties WAT 1276-22-2 were considered good productivity as giving a higher weight of grain (32g). This difference in weight is due to the size of the seeds of these varieties with respect to others. Irrigated rice is the system that gives the greatest return with 4-8 t / ha of paddy, the results of these tests have shown that all tested varieties are profitable with the head of the ranking, the Vo46 variety. The variety Vo46 had produced 7,26t / ha followed by the variety FACAGRO 908 with 5,567t / ha then comes WAT1276-22-2 with 5,133t / ha and 56 FACAGRO with 5,033t / ha.

Abstract: (french)
La présente étude vise l’appréciation de l’adoption de trois variétés de riz de marais d’altitude venues du Centre de Recherche Agronomique/RUBONA du Rwanda aux conditions édapho-climatiques de l’Est de la RD Congo, plus précisément au CRSN/Lwiro en territoire de Kabare au Sud-Kivu. Par ailleurs, nous avons observé que la longueur d’enracinement de ces quatre variétés correspondait à celle déterminée par plusieurs auteurs, la plus longue étant celle de la variété témoin (Vo46) suivie par la variété Facagro 56. Cela a permis de confirmer que le sol de l’Est de la RDC est de bonne structure et texture et est bien aéré ; ce qui facilite le développement racinaire et la nutrition minérale. La variété Facagro 908 s’est placée en première position en ce qui concerne le nombre des talles productives. Ce qui dépend des facteurs comme les bons écartements, les sarclages précoces, la fertilité du sol et le patrimoine génétique favorable. En ce qui concerne le poids de 1000 grains, les variétés Vo46 et WAT 1276-22-2 étaient considérées comme de bonne productivité car donnant un poids plus élevé de grains (32g). Cette différence de poids s’explique par la grosseur des graines de ces deux variétés par rapport aux autres. La riziculture irriguée étant le système qui donne le plus grand rendement avec 4 à 8 t/ha de paddy, les résultats de ces essais ont montrés que toutes les variétés testées sont rentables avec à la tête du classement, la variété Vo46. La variété Vo46 avait produit 7,26t/ha suivie de la variété Facagro 908 avec 5,567t/ha ensuite vient WAT1276-22-2 avec 5,133t/ha et à la Facagro 56 avec 5,033t/ha.
