Striga hermonthica (L) Moench, a parasitic weed species, is a major constraint to sorghum production in the savanna zones of north-eastern Nigeria. The aim of this study was to assess the influence of farmer practices on Striga infestation of sorghum fields in the region. Random sampling techniqu...


Dugje, I.Y.Kamara, A.Y.Omoigui, L.O.[Assessment of farmers' crop management practices influencing Striga hermonthiea infestation and grain yield of sorghum (Sorghum hieolor)]Assessment of farmers' crop management practices influencing Striga hermonthiea infestation and grain yield of sorghum (Sorghum hieolor)

Historically, conventional breeding has been the primary strategy used to develop a number of Striga-resistant varieties currently grown in the Sahel of Western Africa. In this study, we have successfully developed and applied a marker-assisted selection strategy that employs a single backcross p...

Rice production by smallholder farmers in the savannas of Nigeria is constrained by weed competition. A field study was conducted to assess the effect of weed competition on the performance of upland rice varieties in 2005 and 2006 in the northern Guinea and Sudan savannas of Nigeria. The experim...

The moist savannas of West and Central Africa have great potential for maize grain production due to high levels of radiation and reduced incidence of pests and diseases. However, soils in this zone are generally low in organic matter and cation exchange capacity in addition to land use intensifi...


Ajala, S.O.Menkir, A.Kamara, A.Y.Alabi, S.O.Abdulai, M.S.[Breeding strategies to improve maize for adaptation to low soil nitrogen in West and Central Africa]Breeding strategies to improve maize for adaptation to low soil nitrogen in West and Central Africa

Eighteen S1 lines of maize (Zea mays L.) derived from a low nitrogen tolerant pool and two inbred lines were evaluated for agronomic performance under moderate N conditions in the southern Guinea savannah of Nigeria. Generally, the breeding lines differed in yield, growth, vertical rootpulling re...

The risk of drought is high in the Sudan savannah zone of West and Central Africa because rainfall in this area is unpredictable in quantity and distribution. Thus, improved maize genotypes tolerant to drought could stabilize maize grain yield in this zone, where recurrent drought threatens grain...

The weed seed bank under seven fallow tree species was analysed in size and composition five years after tree establishment. The seed bank was lower in Enterolobium cyclocarpum fallows than in the other tree fallows at both 0-5 and 5-10 cm depths. Nuclea latifolia and Terminalia superba tree fall...

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...
