Abstract

Interference of common lambsquarters (Chenopodium album L.) in sugarbeets (Beta vulgaris L. ‘Mono Hy D2′) was determined in a 2-yr field experiment. Yield of sugarbeet roots and recoverable sucrose/ha decreased as the density of common lambsquarters increased. At densities of 6, 12, 18, and 24 common lambsquarters plants/30 m of row, root yields were reduced 13, 29, 38, and 48%, respectively, and recoverable sucrose yields were reduced 11, 27, 37, and 46%, respectively. The minimum number of common lambsquarters plants required per 30 m of row to reduce sugarbeet root yields was estimated to be six in 1980 and four in 1981.
