Abstract : Soybean (Glycine max L.) is a legume grown mainly for its seeds rich in proteins with the proportions of 36.5%. In Democratic Republic of the Congo (DRC or DR Congo), there are several varieties of cultivated soybeans. Since there is a diversity of soils cultivated by farmers, some varieties do not always express their potential. The reason why a study was conducted in N'djili-Brasserie crop scientific station from April20 to August12, 2013 for the first test and from October 2, 2013 to January 12, 2014 for the second test. This study was designed to compare the two used fertilizers, to bring out the best dose of these fertilizers enabling the farmers of this country to increase their production and to evaluate the yield of the variety TGX 888-49 C. The results of the test conducted according to a randomized complete block system with four repetitions showed that Stylosanthes guyanensis (6 Kg/m2) has positively influenced the studied parameters as well in the first test as in the second test of which the best yield was that observed from the first test (2133 Kg/ha) while the lowest yield was observed in the second test (1175 kg/ha). Given the findings, Stylosanthes guyanensis biomass can be retained and recommended as organic fertilizer for soybean production in Kinshasa and its surroundings.
