| Abstract | Une etude de l’impact des oiseaux granivores sur le rendement du riz pluvial (Oryzasativa) en culture pure a ete conduite a l’Institut Superieur d’Etudes Agronomiques (ISEA) de Bokonzi, dans la province du Sud-Ubangi en Republique Democratique du Congo. L’objectif principal de cette etude etait d’evaluer les deficits des rendements de la culture pluviale du riz, causes par les oiseaux granivores dans la zone d’etude.Les resultats des analyses statistiques demontrent que le taux de deperdition du a l’action des oiseaux est de 4,67 % dans les champs surveilles et de 28,35% dans les champs non surveilles soit une perte moyenne a l’hectare de 16,1% de rendement. Ceci traduit une perterespective equivalant a28,35 USD et 167USD soit en moyenne 97,83USD/ha. Ces pertes constituent le deficit socio-economique important pour les riziculteurs.

Impact of granivorous birds on the yield of pluvial rice culture (Oryza sativa L., Poaceae) in the Sud Ubangi Province, DR Congo Abstract A study on the impact of granivorous birds on rice yield was carried out at the Bokonzi High School of Agricultural Studies, located in the Sud-Ubangi province in Democratic Republic of Congo.The aim of the study was to evaluate the yield deficit of rice in husk, due to the birds in study area. The results showed that the rate of deficit due to the birds is 4.67% for fields kept on surveillanceand 28.35% without surveillance (about 16.1% of yield/ha). According of the current price of dry paddy in this area, the yield deficit of rice in value is respectively 28.35 USD and 167 USD with an average of 97.83USD of deficit/ha. This loss of yield constitutesan important economic and social deficit for the rice culture practitioners.
