This study was conducted for two consecutive years
(2008 and 2009) on the
natural rangeland of greater Kordofan region at three sites:,
the main objective was to investigate the variation in
rangeland vegetation as indicated by different growth conditions. The field work was carried out at the start of
rainy seasons and seed setting stages in the three locations.Results showed that the biomass
production at Dilling showed highest values followed by Demokeya and then Bara.
Plant composition in Dilling, showed highest values followed by Demokeya and
then Bara. Litter % in Dilling showed lowest values.
The variations
investigated by the study justify differential management prescriptions that
cater for activities such as seed broadcasting and enrichment of range with
certain plant species. Vegetation cover% was lowest
in Bara followed by Demokeya and then Dilling. Bare soil incidents were higher
in Bara and Demokeya than in Dilling. The crude protein content of herbaceous
biomass was higher in Bara and Demokeya (sandy soil) than in Dilling (clay
soil). The crude fiber content (CF) decrease or increase according to the plant
age in the three sites. The high ash content was in Dilling compared with Bara
and Demokeya. However, in time of sampling, the differences
were recorded in ash but their values decreased by the plant growth. The
differences in dry matter between the seasons and among sites were minor. The
grasses were the dominant plants in the three sites.
The similarity index
indicated that there was
similarity recorded between Bara and Damokeya (45%), followed by Damokeya and
Dilling (30%) and dissimilarity was between Bara and Dilling (3%).
