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...

Infestation of crop fields by Striga species in the savanna zones of northeast Nigeria
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...
Full-sib families derived from Pool 16 DT, a tropical maize ( Zea mays L.) population, were evaluated in the 1995/96 and 1997/98 dry seasons, using two sites each season in Côte d’Ivoire. In all sites, the crop was irrigated from planting to about 2 weeks before anthesis, irrigation was discontin...

North Carolina Design I (NCD I) progenies derived from Pool 16 DT, a white, dent, early maturing, drought-tolerant and streak resistant tropical maize (Zea mays L.) population, were evaluated in the 1995/96 and 1997/98 dry seasons, using two sites each season in Côte d'Ivoire. In all sites, the c...

The semi-arid and arid rangelands of Sub-Saharan Africa are characterized by high variability and by heavy reliance of herders on access to common resources, predominantly pasture and water. In these systems, the capacity of the community to co-operate over resource management is critical and the...

The Borana rangelands of southern Ethiopia are characterised by extensive livestock production in response to the area?s natural characteristics - aggregate mean rainfall ranges between 300 and 900 mm per annum with high seasonal and inter-annual variability. Though traditionally transhumant past...

The parasitic weed, Striga gesnerioides, is a major threat to cowpea productivity throughout the savannas of West and Central Africa. The identification of sources of S. gesnerioides resistance and their incorporation into breeding programs would be a beneficial strategy to combat the devastation...

Infestation of cereals and cowpeas by Striga species constitute a major constraint to increased crop pro-ductivity in the savannas of northern Nigeria. Field surveys were undertaken in Jigawa State, Nigeria in2012 to assess (i) the level and extent of Strgia infestation of cereal and cowpea field...
