Influence Of Improvement Practices On Big Bluestem And Indiangrass Seed Production In Tallgrass Prairies, Robert A. Masters, Robert B. Mitchell, Kenneth P. Vogel, Steven Waller

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Taligrass prairies provide a valuable source of diverse native plant germplasm. Seed harvested from native prairies can be used to revegetate highly erodible or marginal cropland and degraded rangeland if adequate quantities of seed can be produced. The effect of spring burning, fertilization, and atrazine [6-chloro-Nethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine] on big bluestem (Andropogon gerardii Vitman var. gerardii Vitman) and indiangrass [Sorghastrum nutans (L.) Nash] reproductive stem density and seed production was determined in 9 tallgrass prairie environments (each year by site was considered a unique environment). Studies were conducted at tallgrass prairies near Bloomfield, Lincoln, and Virginia, Nebr., from 1987 through …
