It could make a valuable seed bed for horticultural crops such as zucchini, cabbage, bulb onions, and eggplant, as it provides organic matter and protection from wind and sun to the vegetables (Valenzuela et al., 2002). Rhodes grass hay was then able to meet sheep maintenance requirements (x 1.1-1.2) (Mero et al., 1998). When we picture the savanna, we often imagine wide plateaus covered in tall grasses.
