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...

Review of the published and unpublished literature on 'gizu', with particular reference to environment, calendar of occurence, flora composition, plant ecology, sociological aspects & economic aspects of the regional pastoral economy.
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...

Three experiments were conducted in successive years using 32, 53 and 74 crossbred suckler cows respectively, in a semi-arid area close to Nairobi, Kenya. The cows were mated seasonally to calve approximately 1 month before the rainy season (March to May). A 2 X 2 factorial experimental design wi...

The problem of seasonal shortages of herbage production from natural pastures in the Ethiopian highlands was investigated. This was done by comparing the available biomass amounts on the
pastures with biomass amounts required for livestock grazing and for protecting land slope from soil erosion w...
