摘　　要：Field experiments were conducted at Gore near Zebila in Bawku West District of the Upper East Region of Ghana during the 2015 and 2016 cropping season on four Striga tolerant maize varieties in maize/soybean integration alongside maize monocrop as a means of managing the devastating effects of Striga. The study determined the relative Striga tolerance of the maize varieties in terms of yield and yield components, as well as the most effective intercrop for the reduction of Striga seed bank. The treatment differences were not significant (p < 0.05) in affecting plant height, plant population, leaf area index (LAI), Striga count and Striga biomass. Similarly, yield components of maize such as height of cob attachment, cob length, cob weight, 100 seed weight, grain yield, as well as straw weight were not significantly affected by the treatments. There was no relativity of Striga stress tolerance in terms of yield and yield components of the four maize varieties. All the entries efficiently tolerated the biotic stress of Striga and further supported growth and grain yield equally. There was reduced S. hermonthica seed bank production in the soil in both cropping systems. The four maize varieties are proven tolerant materials to Striga infestation and are therefore recommended for long-term Striga seed bank depletion in the study area.Field experiments were conducted at Gore near Zebila in Bawku West District of the Upper East Region of Ghana during the 2015 and 2016 cropping season on four Striga tolerant maize varieties in maize/soybean integration alongside maize monocrop as a means of managing the devastating effects of Striga.
