Cowpea is an important food crop in the dry savannas of West and Central Africa because of its high protein content. Yields are, however, considerably reduced by the parasitic angiosperm Striga gesnerioides. Field trials over 2 years in two localities in northeast Nigeria evaluated the performanc...

Poor soil fertility, especially with low levels of nitrogen (N), is a major constraint to productivity and the production of maize in the Guinea Savanna of Nigeria. To improve efficiency of the maize to use N in the Savanna, maize genotypes with improved root systems to exploit the available N fr...

Response to low soil nitrogen stress of S1 maize breeding lines selected for high vertical rootpulling resistance
The performances of plants and seedlings of 14 tropical-adapted, registered maize hybrids were evaluated under drought stress to assess genotype suitability for off-season planting and to identify parental materials for developing drought tolerant hybrids from locally adapted germplasm. Field eva...
