Journal Article 2017-05-03

Growth and yield responses of cowpea to inoculation and phosphorus fertilization in different environments

Autor: Boahen, S. Savala, C.E.N. Chikoye, D. Abaidoo, R.C.

Cowpea (Vigna unguiculata) is a major source of dietary protein and essential component of the cropping systems in semi-arid regions of Sub-Saharan Africa. However, yields are very low due to lack of improved cultivars, poor management practices, and limited inputs use. The objectives of this stu...

Journal Article 1999

Weed seed bank size and composition in an arable crop mulched with pruning from three multipurpose trees in southwestern Nigeria

Autor: Kamara, A.Y. Akobundu, I.O. Chikoye, D. Jutzi, S.C.

Weed seed bank size and composition were analysed in 1995 and 1996 in maize fields mulched with pruning from Gliricidia sepium, Leucaena leucocephala, and Senna siamea in South Western Nigeria. Plots mulched with pruning from the three trees had a lower weed seed bank in the first year of croppin...

Performance of semideterminate and indeterminate cowpeas relaycropped into maize in Northeast Nigeria

Autor: Kamara, A.Y. Omoigui, L.O. Ewansiha, S.U. Ekeleme, F. Chikoye, D. Ajeigbe, Hakeem A.

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,...

Field performance of improved cowpea varieties under conditions of natural infestation by the parasitic weed Striga gesnerioides

Autor: Kamara, A.Y. Chikoye, D. Ekeleme, F. Omoigui, L.O. Dugje, I.Y.

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...

Influence of insecticide spraying regimes and cultivar on insect pests and yield of cowpea in the dry savannas of northeastern Nigeria

Autor: Kamara, Y. Chikoye, D. Omoigui, L.O. Dugje, I.Y.

Cowpea is an important food legume and versatile crop in the savannas of northeast Nigeria. Despite the high potential for production in this region, insect pests are a major constraint. A study was conducted to evaluate the response of diverse cowpea genotypes to different schedules of spraying ...

Response of weeds and soil microorganisms to imazaquin and pendimethalin in cowpea and soybean

Autor: Chikoye, D. Abaidoo, R.C. Fontem, Lum. A.

Herbicides applied to combat weeds and increase crop yields may also have undesired effects on beneficial soil microorganisms. Field studies were conducted in 2005 and 2006 in Zaria, Nigeria, to evaluate the response of weeds and soil microorganisms to imazaquin applied at 0.05, 0.10, 0.20 an...

Improving the productivities of cowpeacereal systems in the savannas of West Africa through dissemination of improved varieties and cropping systems

Autor: Ajeigbe, Hakeem A. Singh, B. Kamara, A. Chikoye, D. Adamu, R.S. Saidou, A.K. Adeosun, J.O.

Cowpea (Vigna unguiculata [L.] Walp.) is the most important grain legume in the dry savannas of West Africa, however grain and fodder yields are low (averaging 25 to 300 kg and 450 to 800 kg grain and fodder/ha, respectively) due to biotic and abiotic constraints. Improved varieties and cropping ...
