Increased production is one of the essential elements in the fight against hunger and malnutrition. In DR Congo, rice is both a food and an economic issue. To keep nourishing an increasing population, the increase of rice yield through the development of improved varieties and cultivation techniques would enable this population to have enough food. With this in mind, a study was undertaken at INERA YANGAMBI to compare the yield of rice varieties sown traditionally by farmers in Yangambi by at the onset and at the end of the A season in order to minimize losses due to birds. Yield components (panicle length, number of panicles per m², number of grains per panicle and weight of thousand grains) and yield were evaluated. Results revealed that the performance components taken together influenced performance. The optimum yield of short and medium cycle varieties was obtained on June 15th and 29th. Short cycle varieties can be sown from June 15th and medium cycle varieties at the end of June. From this study it can be remembered that the farmer practice of sowing rice in June is to be encouraged.

Abstract: (french)
L’accroissement de la production constitue un des éléments essentiels de la lutte contre la faim et la malnutrition. En RD Congo, le riz constitue un enjeu à la fois alimentaire et économique. Devant une population sans cesse croissante, l’accroissement du rendement du riz par la mise au point des variétés améliorées productives et des techniques culturales, permettrait à cette population d’avoir suffisamment de la nourriture. C’est dans cette optique qu’une étude a été entreprise à l’INERA YANGAMBI pour comparer le rendement des variétés de riz semées traditionnellement par les paysans de Yangambi en début et à la fin de la saison A pour minimiser les pertes dues aux oiseaux.Les composantes de rendement (la longueur de la panicule, le nombre de panicules par m², le nombre de grains par panicule et le poids de mille grains) et le rendement ont fait l’objet d’une évaluation. Les résultats obtenus ont révélé que les composantes de rendement prises ensemble influençaient le rendement. Le rendement optimum des variétés à cycle court et moyen était obtenu aux dates de 15 et 29 juin. Les variétés à cycle court peuvent être semées à partir du 15 juin et les variétés à cycle moyen à la fin du mois de juin. De cette étude on peut retenir que la pratique paysanne de semis du riz au mois de juin est à encourager.
