Dry bean cultivars were evaluated for suppression of late-season weed emergence near Scottsbluff, NE in 1993 and 1994. The 12 cultivars differed in plant canopy architecture and the amount of light intercepted. In 1993, the vine growth habit of Pinto 'D-84354' provided a more dense canopy and more yellow foxtail suppression than Pinto 'RS-101' that had an upright growth habit. Growing season also influenced plant canopy and late season weed emergence. Cooler temperatures in 1993 resulted in a less dense Navy 'Mayflower' canopy which provided less redroot pigweed suppression than warmer conditions in 1994 that resulted in a more dense crop canopy. No difference in weed suppression was observed among cultivars for common lambsquarters, common purslane, and hairy nightshade. Nomenclature: Common lambsquarters, Chenopodium album L. #3 CHEAL; common purslane, Portulaca oleracea L. # POROL; hairy nightshade, Solanum sarrachoides, Sendt. # SOLSA; redroot pigweed, Amaranthus retroflexus L. # AMARE; yellow foxtail, Setaria glauca L. Beauv. # SETLU; dry bean, Phaseolus vulgaris L. Great Northern, Pinto, Navy, Black Turtle, Light Red Kidney, Small White, Cranberry, Pink, 'Harris,' 'Marquis,' 'D-84354,' 'RS-101,' 'Mayflower,' 'Fleetwood,' 'UI-906,' 'T-39,' 'Sacramento,' 'Aurora,' 'Variety 74,' 'Viva.'.
