Abstract : Among the foodstuffs having a nutritional value in Democratic Republic of Congo (DRC), there is the corn crop. It is the second food crop after cassava with a high energetic value in calories and proteins. However, its production remains low in Kinshasa because of the poor quality of soil and less appropriate techniques for its production. It is therefore essential to define new more appropriate strategies in order to increase its availability locally. It is in this context that a study was conducted at the Ndjili-Brasserie station for the purpose of assessing the effect of different legumes in crops associated with maize, and implementing technique of simple and adaptable production notably the QPM maize based association system and other food legumes that can play a key role in the soil fertility improvement. According to a randomized complete block system with four repetitions, the data collected were analyzed using the method of analysis of variance (ANOVA) with 5% likelihood point completed by the test of the least significant difference (LSD) to compare the different observed parameters. The findings indicate that T1 (QPMCorn + Peanut) and T2 (QPMCorn + Soybean) respectively influenced more vegetative parameters positively than the others. As for the estimated yields, the highest values were recorded in T1 (7.33 tons/ha) followed by T2 (7.03 tons/ha) and T3 (2.95 tons/ha) gave the lowest yield. To that end, T1 (QPM Maize + Groundnut) and T2 (QPM Maize + Soybean) can be kept and recommended to farmers in Kinshasa as varieties of associated crops focusing particularly on T1 (Peanut) for its effectiveness in nodulation and its relatively high yield.
