Abstract
The study evaluated seven varieties of cowpea, Vigna unguiculata (L.) Walp., namely: Ife Brown, IT98K-128-3 , IT98K-506-1, IT93K-452-1 and IT95K-1072-57, IT06K-149-1, and IT06K136 that were laid out in a complete randomized block design (CRBD) with seven replications for the production of root nodules. It comprised of two field trials (during the wet season and the dry season of 2021 cropping season respectively) that were carried out at an experimental garden in Agbor, Delta State. The rainy season plants were rain-fed while the dry season experiment was watered manually when the rainy season finally ended. The study established that nodulation was a primary determinant of the agronomic and yield characteristics of legumes. Consequently, genotypes with large number of nodules per plant recorded more peduncles, pods per plant, longer pod lengths and consequently gave better grain yield and were recommended for inclusion in further cowpea hybridization programmes in the region
