Conteúdo: 	The production, density and height of flower stalks of Adropogon gerardii, Shizachyrium scoparium and Sorghastrum nutans were surveyed over a four-year period (1981-1984) on burned vs. unburned and shallow vs. deep soil sites in native, undisturbed tallgrass prairie. In general, flower stalk height was greater on deep than the shallow soils but the response of height to fire was variable. In contrast, density and production of flower were usually greater on the annually burned sites, whereas soil effects were inconsistent. Production of flower stalks for all three species combined ranged from 0 to 670 g/m2 during the 4-year period with maximum production occurring in a mesic year which followed a drought year.
