Soil improver and soil erosion control
Zornia glabra is a N-fixing legume that readily nodulates when it is sown in its native environment. It was shown that its integration in natural fallow, despite dry season forage utilisation, increased grain yields of subsequently grown maize by up to 52% on experimental site in Nigeria (Muhr et al., 1998). As a ground cover, zornia could hardly cover 30% of the ground in two sites (one experimental and one managed by farmer) of South West Nigeria (Muhr et al., 1999).
