Title

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.

Jia Gao; Lin Li; Risheng Ding; et al. Agricultural Water Management 2024. doi:10.1016/j.agwat.2024.109260

Other claims from this paper (11)

Intervention effect Deficit irrigation and salt stress increased leaf WUEi and water productivity of maize.
Intervention effect Deficit irrigation in DS0 significantly increased maize water productivity by 11.5 % relative to the control FS0.
Intervention effect Salt stress alone in FS1 significantly increased maize water productivity by 9.6 % relative to the control FS0.
Intervention effect Combined deficit irrigation and salt stress decreased maize water productivity by 3.5 % relative to the control FS0.
Mechanism The WP increase under single water or salt stress was attributed to reduced evapotranspiration.
Intervention effect Deficit irrigation and salt stress had adverse effects on leaf morpho–physiological traits and dry matter accumulation of maize.
Intervention effect Salt severely inhibited the recovery ability of maize after rewatering.
Intervention effect Literature synthesis showed that deficit irrigation increased maize WP by 10.5 %.
