Badu-Apraku, B.Yallou, C.Oyekunle, M.Akinwale, R.Aweke, G.Kamara, A.[Consistency of performance of early-maturing maize cultivars in Striga infested and Striga-free environments]Consistency of performance of early-maturing maize cultivars in Striga infested and Striga-free environments

The Bill and Melinda Gates Foundation (BMGF) provided a 4-year financial support to the International Institute for Tropical Agriculture (IITA) and other partners in 2011 to adapt and intensively promote proven integrated Striga management strategies in cowpea and maize farming systems in north...


Amaza P.Hassan, M.B.Abdoulaye, TahirouKamara, A.Oluoch. M.[Mid-term and cost-benefit study of smallholder farmers in Striga-Infested maize and cowpea growing areas of Northern Nigeria]Mid-term and cost-benefit study of smallholder farmers in Striga-Infested maize and cowpea growing areas of Northern Nigeria

Most crop simulation models require the use of Genotype Specific Parameters (GSPs) which provide the Genotype component of G×E×M interactions. Estimation of GSPs is the most difficult aspect of most modelling exercises because it requires expensive and time-consuming field experiments. GSPs could...


Adnan, A.A.Diels, J.Jibrin, J.M.Kamara, A.Craufurd, Peter Q.Shaibu, A.S.Mohammed, B.Tonnang, Henri E.Z.[Options for calibrating ceres-maize genotype specific parameters under data-scarce environments]Options for calibrating ceres-maize genotype specific parameters under data-scarce environments

Grain yields of cowpea [Vigna unguiculata (L.) Walp.] in the Nigerian savannas are low even with the cultivation of improved varieties. The recommended spacing for cowpea is 75 × 20 cm with two seeds planted per stand. This corresponds to plant population of 133333 plants ha−1, which may not be s...


Kamara, A.Tofa, A.I.Kyei-Boahen, S.Solomon, R.Ajeigbe, Hakeem A.Kamai, N.[Effects of plant density on the performance of cowpea in Nigerian Savannas]Effects of plant density on the performance of cowpea in Nigerian Savannas

Maize farmers and extension agents in dry sudan savanna need information on how planting date and the choice of variety affect grain yield. This study was conducted to test the ability of model to predict maize yields under varying planting dates. Data on two open-pollinated maize cultivars (TSB-...


Jibrin, J. M.Kamara, A.Ekeleme, F.[Simulating planting date and cultivar effects on dryland maize production using CERESmaize model]Simulating planting date and cultivar effects on dryland maize production using CERESmaize model

Maize (Zea mays) has traditionally been a major cereal staple in southern Ghana. Through breeding and other crop improvement efforts, the zone of cultivation of maize has now extended to the northern regions of Ghana which, hitherto, were the home to sorghum and millet as the major cereals. Maize...


MacCarthy, Dilys S.Adiku, Samuel G.K.Freduah, B.S.Gbefo, F.Kamara, A.[Using CERES-maize and ENSO as decision support tools to evaluate climate-sensitive farm management practices for maize production in the northern regions of Ghana]Using CERES-maize and ENSO as decision support tools to evaluate climate-sensitive farm management practices for maize production in the northern regions of Ghana

Cowpea covers the largest area of any grain legume in Africa and is especially important in West Africa where Nigeria and Niger alone account for over 75% of the total cowpea production in the world. Despite successes of international and national cowpea improvement research in the development an...


Manda, J.Alene, A.Hirpa Tufa, A.Abdoulaye, TahirouKamara, A.Olufajo, O.Boukar, O.Manyong, Victor M.[Adoption and ex-post impacts of improved cowpea varieties on productivity and net returns in Nigeria]Adoption and ex-post impacts of improved cowpea varieties on productivity and net returns in Nigeria

McCarthy, N.Kamara, A.Kirk, M.[The effect of environmental variability on livestock and land-use management: The Borana plateau, southern Ethiopia ]The effect of environmental variability on livestock and land-use management: The Borana plateau, southern Ethiopia 

To address the problem of the continued deterioration of livelihood and food security in the sub Saharan Africa, the Forum for Agricultural Research in Africa (FARA) through the sub Saharan Africa Challenge Programme (SSA CP) is implementing the Integrated Agricultural Research for Development (I...


Olarinde, L.O.Abdoulaye, TahirouKamara, A.Binam, J.Adekunle, A.[Using a linear discriminant analysis approach of baseline conditions to develop household categories in the Sudan Savanna ( KKM PLS SSA CP ), Nigeria]Using a linear discriminant analysis approach of baseline conditions to develop household categories in the Sudan Savanna ( KKM PLS SSA CP ), Nigeria

This article provides an assessment of the potential impact of operationalizing agricultural innovation platforms (IPs) in the Sudan Savannah zone of Nigeria on adoption of improved maize/legume crop varieties, as measured by the potential outcome approach. The results show that, if the whole pop...
