Summary: Nodulation, dry matter and grain yields of two promiscuous (Magoye and Local) and two specific (Roan and Nyala) soybean varieties grown at three field sites in Zimbabwe were compared. Rhizobial numbers were higher in soils with a history of soybean and ranged from 15 to 11 million cells per gram of soil using Magoye as the trap host. In general nodule numbers did not respond to inoculation in promiscuous varieties and only increased slightly in specific varieties. Promiscuous varieties had comparable grain yields, higher dry matter and lower grain harvest indices compared to specific varieties without inoculation. Our results suggest that promiscuous soybean has potential under low input cropping systems where rhizobia inoculants may not be readily available.
