Cowpea is a major food and cash crop in northern Nigeria, providing nutritious grain and a less expensive source of protein for both the rural poor and urban consumers. A number of improved varieties have been developed combining diverse plant type, and different maturity periods, with resistance...
For a long time, farmers in Nyanza and Western provinces in Kenya have had to deal with the Striga problem. To most of them Striga had become a way of life and they had given up hope. Striga affects their mainstay crops, which are maize, sorghum and mil- let. After an extensive search for...
Drought occurrence and striga hermonthica (Del.) Benth infestation are formidable maize (Zea mays L.) production constriants in the savanna zones of West and Central Africa (WCA). The West and Central Africa collaborative Maize Research Network (WECAMAN), in collaboration with the International I...
In southern Africa the repeated cultivation of maize (Zea mays) and climate variability (especially frequent and extended droughts) have created conditions favouring parasitic weed infestation (e.g., Striga asiatica). In the past decade, Striga has reduced maize yields for smallholder farmers (cu...
Striga hermonthica can cause as high as 100% yield loss in maize depending on soil fertility level, type of genotype, severity of infestation and climatic conditions. Understanding the mode of inheritance of Striga resistance in maize is crucial for introgression of resistance genes into tropical...
The magnitude and type of genetic variability are of prime importance to breeders in determining whether or not to improve a breeding population and the method to use. The early maturing population, TZE-W Pop DT STR, has gone through three cycles of S1 recurrent selection for improvement for grai...
Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers...
