Dugje, I.Y.Kamara, A.Y.Kwari, J.D.[Analyses of soil physico chemical properties determining Striga hermonthica infestations and grain yield of maize (Zea mays L.) in nigerian Guinea and Sudan savannas]Analyses of soil physico chemical properties determining Striga hermonthica infestations and grain yield of maize (Zea mays L.) in nigerian Guinea and Sudan savannas

An assessment of the genetic diversity among extra-early maturing maize inbred lines would be useful for identifying closely related lines, in determining the variation in genetic similarity among genotypes that show no variation for parentage and in planning crosses between genetically divergent...


Badu-Apraku, B.Menkir, A.Lum, A.F.[Assessment of genetic diversity in extraearly Strigaresistant tropical inbred lines using multivariate analysis of agronomic data]Assessment of genetic diversity in extraearly Strigaresistant tropical inbred lines using multivariate analysis of agronomic data

Striga and drought are major constraints to maize (Zea mays L.) production in the savannas of west and central Africa (WCA). A study was conducted in 2005 and 2006 in Nigeria to determine the level of resistance to Striga hermonthica for two early-maturing maize populations, one white and one yel...


Badu-Apraku, B.Fakorede, M.A.B.Lum, A.F.[S1 family selection in early maturing maize populations in Striga infested and Striga free environments]S1 family selection in early maturing maize populations in Striga infested and Striga free environments

Maize (Zea mays L.) production in west and central Africa (WCA) is constrained by the parasitic weed Striga hermonthica (Del.) Benth and recurrent drought. Two early maize populations, TZE-W Pop DT STR C0 (white) and TZE-Y Pop DT STR C0 (yellow), developed from diverse genetic backgrounds, were s...


Badu-Apraku, B.Lum, A.F.Fakorede, M.A.B.Menkir, A.Chabi, Y.The, C.Abdulai, M.Jacob, S.Agbaje, S.[Performance of early maize cultivars derived from recurrent selection for grain yield and Striga resistance]Performance of early maize cultivars derived from recurrent selection for grain yield and Striga resistance

Field studies were conducted in 1995 and 1996 in the northern Guinea savanna of Nigeria to determine the response of 22 soybean genotypes to Alectra infestation. Significant differences were observed amongst soybean genotypes in number of Alectra shoots that emerged at 9 and 10 weeks after sowing...


Kureh, I.Alabi, S.Kamara, A.[Response of soybean genotypes to Alectra vogelii infestation under natural field conditions]Response of soybean genotypes to Alectra vogelii infestation under natural field conditions

On-farm trials were conducted in 2001, 2002, and 2003 in the northern Guinea savanna of Nigeria to evaluate integrated Striga hermonthica control measures under farmermanaged conditions. These included intercropping a Striga-resistant maize variety with cowpea for 3 years and also cropping this m...


Kureh, I.Kamara, A.Y.Tarfa, B.D.[Influence of cereal legume rotation on Striga control and maize grain yield in farmers fields in the northern Guinea Savanna of Nigeria]Influence of cereal legume rotation on Striga control and maize grain yield in farmers fields in the northern Guinea Savanna of Nigeria

The average productivity of cowpea in the existing traditional systems is low due to a complex of biotic and abiotic stresses. The biotic factors include insect pests, parasitic plants, and viral, fungal and bacterial diseases. Concerted efforts are being made to develop improved cowpea varieties...


Ajeigbe, Hakeem A.Singh, B.B.Emechebe, A.M.[Field evaluation of improved cowpea lines for resistance to bacterial blight, virus and striga under natural infestation in the West African savannas]Field evaluation of improved cowpea lines for resistance to bacterial blight, virus and striga under natural infestation in the West African savannas

The potential maize (Zea mays L.) yield in the savannas of West and Central Africa (WCA) is constrained by Striga hermonthica (Del.) Benth. parasitism. Field trials at Ferkessedougou, Côte d'Ivoire; Abuja, Nigeria; and Mokwa, Nigeria, in 2002, and at Mokwa and Abuja in 2004, evaluated the perform...


Badu-Apraku, B.Lum, A.F.[Agronomic performance of striga resistant early-maturing maize varieties and inbred lines in the savannas of West and Central Africa]Agronomic performance of striga resistant early-maturing maize varieties and inbred lines in the savannas of West and Central Africa
