Impact of granivorous birds on the yield of rainfed rice Or(yza sativa L.) in 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.
