The main objective of this study was to determine the macro minerals in the feed potassium K and calcium Ca at the flowering and seed setting stages on the natural range land. Sampling was done by locating 2km2 each stage at the plants maturity (flowering and seed setting stages). A completely randomized design (CRD) was used to selected samples of feed. The results indicated that stages effect on feed macro minerals concentration were significantly (P<0.001) higher potassium K (0.22 ppm) concentration at the flowering stage and lower potassium K (0.07 ppm) concentration at the seed setting stage. There was increased calcium Ca (8.02 ppm) concentration at the flowering stage and decreased Ca (6.76 ppm) concentration during the seed setting stage.
