Forage production of 16 C. rotundifolia accessions was compared with that of Stylosanthes scabra cv Seca under grazing in a subhumid, medium altitude acid soil site at Soddo, southern Ethiopia. Large variations were observed in dry matter production, days to flower initiation, canopy height and c...

The effects of 4 years grazing by sheep and goats at various stocking rates on soil surface features, bulk density, organic C, N and P contents and pH were investigated in Sadore, Niger. Studies were also conducted in a fallow subjected to 9 years of intensive grazing. Although grazing reduced (P...
