Field trials were conducted in 2005 and 2006 in Tilla (northern Guinea savanna) and Sabon-Gari (Sudan savanna) in northeast Nigeria to determine the performance of two improved cowpea varieties when relay-intercropped with early and late maize, 6 and 8 weeks after planting the maize. Grain yield,...

Striga gesnerioides is considered a major constraint to improving cowpea productivity in the semi arid region of Africa. A field survey was conducted in a farmer participatory process in 100 cowpea fields to determine farmers’ crop production practices that influence infestation by the parasitic ...


Dugje, I.Y.Kamara, A.Y.Ekeleme, F.[Evaluation of farmers crop production practices that determine Striga gesnerioides infestation of cowpea fields in Nigerian savannas]Evaluation of farmers crop production practices that determine Striga gesnerioides infestation of cowpea fields in Nigerian savannas

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...


Kamara, A.Y.Chikoye, D.Ekeleme, F.Omoigui, L.O.Dugje, I.Y.[Field performance of improved cowpea varieties under conditions of natural infestation by the parasitic weed Striga gesnerioides]Field performance of improved cowpea varieties under conditions of natural infestation by the parasitic weed Striga gesnerioides

Infestation of cereals and cowpeas by Striga species constitute a major constraint to increased crop pro-ductivity in the savannas of northern Nigeria. Field surveys were undertaken in Jigawa State, Nigeria in2012 to assess (i) the level and extent of Strgia infestation of cereal and cowpea field...


Kamara, A.Ekeleme, F.Jibrin, J.M.Tarawali, G.Tofa, A.[Assessment of level, extent and factors influencing Striga infestation of cereals and cowpea in a Sudan Savanna ecology of Northern Nigeria]Assessment of level, extent and factors influencing Striga infestation of cereals and cowpea in a Sudan Savanna ecology of Northern Nigeria

The parasitic weed Striga gesnerioides (Willd) Vatke is one of the most important constraints to cowpea production in the dry savanna. Yield losses due to S. gesnerioides range from 83 to 100%. No single method however seems to be fully adequate in the control of this parasite. One practice, host...
