Hager, Aaron Gregory 2015-09-28T16:22:30Z 2015-09-28T16:22:30Z 10000-01-01 2001 2001 Field experiments were conducted during 1996, 1997, and 1998 to determine the common waterhemp interference period soybean could tolerate without reducing seed yield. Removal of common waterhemp interference 2 weeks after soybean unifoliolate expansion resulted in soybean seed yield equivalent to a season-long weed free control, but delaying common waterhemp removal longer than 2 weeks resulted in decreased soybean seed yield. Full season common waterhemp interference reduced soybean seed yield 31%. These results suggest soybean producers should implement common waterhemp management strategies prior to 4 weeks after soybean unifoliolate leaf expansion to reduce potential loss of soybean seed yield.
