Adaptation d'un cultivar de Niébé (Vigna unguiculata (L.) Walp.) aux conditions pédoclimatiques de Boundji (République du Congo)

Adaptation of one cultivar of Cowpea (Vigna unguiculata (L.) Walp.) to climatic and soil conditions of Boundji (Republic of Congo). The study on cowpea cultivar in the Boundji area in Republic of Congo is justified by the research of forage plants used for pasture improvement. The objective of this study is to have preliminary results on the growth and production of this cultivar of cowpea in relation to soil and climatic conditions of the area. The germination of seeds was evaluated before planting and after harvest. Sowing was done online on ridges with a spacing of 75 cm x 50 cm. The results show that cowpea has a good germination (92 %), growth is normal, average leaf production is good two months after sowing (888 kg / ha) and dry seeds harvested at three-month low (184 kg / ha). This cultivar is well adapted to the ecological conditions of the area. High
