Topic Description: Common bean is a staple food in the Democratic Republic of Congo. Today, its productivity in the territory of Kasongo-Lunda is threatened by abiotic and biotic constraints, the basis of the increase in poverty and food insecurity. Objective: The objective of this study is to identify the agronomic constraints that limit the cultivation of common beans, and to evaluate the cultivation techniques related to the decline in production in the Kasongo-Lunda territory. Methodology and results: Twelve (12) villages in the territory of Kasongo-lunda were surveyed in February and May 2021.A survey was carried out among 331 common bean producers chosen according to the approach determined by the respondent (Snowball sampling) thus mobilizing the tools and techniques of regional agronomic diagnosis based on interview surveys, group and/or individual interviews using questionnaires and field visits. The results showed that the early and/or late return of rains, non-compliance with the fallow period, staking difficulties, lack of rotation, the producer’s experience in cultivation, weeds, diseases and pests, soil infertility, degeneration of varieties, lack of supervision of producers, use of rudimentary tools, ineffective means of control limit bean cultivation. The evaluation of technical itineraries revealed that land selection, land preparation, seed selection, sowing date, number of seeds per pocket, staking, number of weeding, stage of attack of diseases and pests influence the yield of common beans in the territory of Kasongo-lunda. Conclusion and application of the results: By accurately identifying agronomic constraints and evaluating appropriate cultivation techniques, producers were able to maximize common bean production while minimizing pest risks.
