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 did not decrease cotton branch dry weight in ultra narrow rows.
- Mechanism In wide rows, yield decrease under spurred anoda interference was attributed to reduced boll retention or fruiting sites.
- 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.
