Objective: The effect of the 4 fertilizer doses was evaluated on the variability of the elements of the structure of local pea production (Pisumsativum L.S) in the Brazzaville area of the Republic of Congo. Methodology and results: In the field, the production parameters were observed during the development phase with different doses of fertilizer. variants with introduction of a minimum of fertilizer doses (N12, 5 P15 K 15) and nitrogen fertilizers (N25) against the background of the average soil phosphorus and potassium supply, as well as when using the The effect of an organomineral fertilization system (NPK and manure post-effect) was the increase in the number of pods per plant compared to the control (control) variant of 26.5%, 21.2% and 23%, respectively., 0%. The maximum of this indicator is in the variant with the introduction of an average dose of mineral fertilizer (N25 P30 K30) is 4.93 pods per plant. Conclusion and application of results: The increase in fertilizer doses contributes to the direct growth of the following indicators: seed weight per plant, straw weight and seed of unit area, seed yield by plant; these indicators will help to improve farming practices in the countryside for better productivity.
