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 minor similarity recorded between Bara and Damokeya (45%), followed by Damokeya and Dilling (30%) and dissimilarity was between Bara and Dilling (3%).
