Stability of grain and fodder yields in extra-early cowpea genotypes in Southeastern Niger
Cowpea [Vigna unguiculata (L.) Walp.] is a vital food and fodder crop in Niger, but its productivity is constrained by drought, poor soils, striga and pest pressures. Developing extra-early dual-purpose varieties is essential for strengthening food and feed security in these fragile production zones. This study evaluat...
