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

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-...

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

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...

Parasitism of crop plants by Striga species is a major constraint in the savanna zones of West Africa. Farmers ranked Striga as a leading constraint during a livelihood analysis of 30 communities in northeast Nigeria. A field survey was conducted to ascertain the extent of infestation by Striga s...

Abstract A field experiment was conducted during 2014 and 2016 rainy season at Tudun Wada, Kano and Shika, Zaria in the Northern Guinea Savanna of Nigeria in order to study the physiological responses of maize hybrids under low nitrogen. The experiment consisted of two nitrogen levels 0 and 120 N...
