French bean (Phaseolus vulgaris L.) is a major vegetable export crop in Kenya and a potential income earner to small - scale farmers. However, the crop poorly tolerates saline soils. Small scale farmers in Nyatike sub-county, Migori county have embarked on growing French beans but have encountered soil salinity problem. A study was carried out to determine the effects of purslane (Portulaca oleracea) grown as an intercrop on French bean production in saline soil.
