Abstract

The objective of this study is to improve pea yield and quality of the (local) variety from the use of mineral and organic fertilizers. Four doses, alone or in combination, of nitrogen, phosphorus and potassium were made on pea (local) variety plants. Organic fertilizers were supplied in the form of rotten manure. Protein content in seed, protein collection, and pea yield based on mineral doses were compared to unfertilized plants. NPK and manure intake increased the best yield in 2017. Interactions (N25 P 30K 30) and (N 12,5P 15K 15) also performed better in 2016 and 2018.The best protein content was observed in 2017 with the use of post effect organic and mineral fertilizers. The combined contribution of mineral and organic fertilizers improves the protein content and yield of the (local) pea variety.;.

Key words: pea, mineral nutrition, culture, Brazzaville.
