Spurred anoda (Anoda cristata) interference in wide row and ultra narrow row cotton

William T. Molin; Debbie Boykin; Josie A. Hugie; et al. Weed Science 2006. doi:10.1614/ws-05-072r1.1

Other claims from this paper (15)

Association Spurred anoda density and dry weight per plot were linearly related each year.
Observation At 8 m −2, spurred anoda dry weight was 507 g m −2 in 2000.
Observation At 8 m −2, spurred anoda dry weight was 322 g m −2 in 2001.
Observation At 8 m −2, spurred anoda dry weight was 777 g m −2 in 2002.
Intervention effect Spurred anoda did not interfere with seed cotton yield in 2001.
Intervention effect Yield losses exceeded 55% at spurred anoda density of 8 m −2 in both row spacings relative to controls.
Association The effect of spurred anoda density on cotton boll numbers was nearly identical in 2000 and 2002 across cultivar and row spacing.
Intervention effect Boll weights decreased with spurred anoda interference.
Intervention effect Spurred anoda interference decreased cotton branch dry weight in wide rows.
Intervention effect Spurred anoda interference did not decrease cotton branch dry weight in ultra narrow rows.
Mechanism In ultra narrow rows, yield decrease under spurred anoda interference was attributed to plant mortality.
Association Cotton plant density decreased by one plant for each additional spurred anoda in ultra narrow rows.
Intervention effect Yield per surviving cotton plant remained constant under spurred anoda interference in ultra narrow rows.
Intervention effect Neither row spacing conferred significant advantage in response to spurred anoda interference.
Recommendation Decreased boll weight and lack of compensatory boll number increase in ultra narrow rows may limit producer appeal.
