Grain yields of cowpea [Vigna unguiculata (L.) Walp.] in the Nigerian savannas are low even with the cultivation of improved varieties. The recommended spacing for cowpea is 75 × 20 cm with two seeds planted per stand. This corresponds to plant population of 133333 plants ha−1, which may not be s...

Effects of plant density on the performance of cowpea in Nigerian Savannas
Field studies were conducted during the 2014 and 2015 wet seasons at Zaria in the northern Guinea savanna and at Iburu in the southern Guinea savanna of Nigeria to determine the productivity of maize– soybean intercropping system. There were four treatment combinations in the experiment: sole mai...

Maize-soybean intercropping for sustainable intensification of cereal-legume cropping systems in northern Nigeria
The goal of this research was to evaluate diverse cowpea genotypes developed over the past 4 decades in the Nigerian
Sudan Savannas for their agronomic performance and to identify groups of cultivars with similar quantitative characters.
Characterization would facilitate the efficient synthesis o...
