Abstract: A field experiment was carried out at Gore in the Bawku West District of the Upper East Region during the 2016 cropping season to determine the effect of maize- soybean intercrop on Striga hermonthica seed bank, crop growth, and yield. The experiment was laid out in Randomized Complete Block Design with three replications on four drought and Striga tolerant maize varieties intercropped with and without soybean variety Afayak. Treatments reduced the initial S. hermonthica seed bank with a minimum of 5% and maximum of 26% for sole Omankwa and Wang data/Afayak respectively. At 12WAP, Omankwa, Aburohemaa, and Wang data intercrops promoted Striga emergence count and biomass production. Bihilifa/ Afayak supported the tallest plant height of maize whilst sole Omankwa gave the shortest. Days to 50% flowering of maize varied significantly with Aburohemaa/ Afayak, sole Omankwa and sole Bihilifa flowered early in 53 days whilst sole Aburohemaa flowered late in 56 days. Bihilifa/ Afayak produced the highest cob weight whilst Omankwa /Afayak produced the lowest. Highest grain yield of maize was obtained with Wang data/ Afayak (1149kgha-1) whilst sole Omankwa produced the lowest grain yield of 850kgha-1. Bihilifa/Afayak gave the highest grain yield of soybean whilst Omankwa /Afayak gave the lowest yield. The maize varieties proved tolerant to Striga infestation whilst the Afayak intercropped with any of the varieties could cause suicidal germination of Striga seeds, Striga seed bank depletion, and for improved crop growth and increased yield. Maize varieties intercropped with soybean (Afayak) have the potential to increase soil fertility.
