Potential contribution of lablab residues to maize production in moist savanna of West Africa

Autor: Ewansiha, S.U. Tarawali, Shirley A. Odunze, A. Iwuafor, E.

Soils of the moist savanna of West Africa are poor in nitrogen; the natural fallow regeneration time has shortened; fertilizer costs and scarcity makes nitrogen (N) fertilizer input inadequate; and crop yields are low. In the region, lablab (Lablab purpureus L., sweet also known as Dolichos labla...

Response of old and new cowpea varieties to insecticide spray regimes in the Sudan savanna of Nigeria

Autor: Kamara, A. Ewansiha, S.U. Ajeigbe, Hakeem A. Omoigui, L.O.

Insect pests are major constraint to cowpea production in northern Nigeria causing yield losses up to 70%. Several cowpea varieties have been developed and delivered to farmers by IITA over the past four decades. These varieties have varying degrees of resistance to insect pest attacks. A field s...

Yield, N uptake and N utilization of early maturing, drought and striga-tolerant maize varieties under low N conditions

Autor: Kamara, A. Ewansiha, S.U. Tofa, A.I.

Performance under sub-optimal nitrogen (N) conditions, of early maturing maize cultivars bred for tolerance to drought and Striga parasitism in the Nigerian savanna is not known. This study evaluated the tolerance of selected early maturing drought and Striga-tolerant maize cultivars to low N con...
