Abstract

Studies were conducted at Grand Rapids, MN, to determine the effect of giant burreed (Sparganium eurycarpum Engelm. No. 3 SPGEU) planted at 6, 12, and 24 corms/m super(2) on wild rice (Zizania palustris) L. "K2") growth and yield. Giant burreed, a spreading perennial, had shoot densities of 21, 29, and 42/m super(2) at harvest for the 6, 12, and 24 corms/m super(2) treatments, respectively. Wild rice yield and panicle number were reduced approximately 60% when giant burreed shoot density was 40/m super(2) or higher when compared to the weed-free control. Reduction of PAR penetration into the wild rice canopy appears to be the major mechanism of giant burreed interference with wild rice.
