Organism: Gossypium hirsutum ✕

Recommendationauthor interpretationoriginal resultmixedbasis n/a

Claim · model-written summary

The authors conclude an arsenical herbicide generally increases sicklepod control but may delay cotton maturity and decrease yield.

Taxon: cottonGossypium hirsutume0
Interactor: sicklepode0weed
Outcome: addition of an arsenical herbicide to pyrithiobace0
Qualifier: potential to delay maturity and decrease cotton yielde0

Verbatim

“Where sicklepod is present, the addition of an arsenical herbicide to pyrithiobac will generally increase control but has the potential to delay maturity and decrease cotton yield equal to the arsenical herbicide applied alone.”

Intervention effect Soil salt content was lowest under the −20 kPa SWP threshold.
Intervention effect Soil salinity was controlled below the root zone under the −20 kPa SWP threshold.
Intervention effect SWP thresholds of −10 and −20 kPa could well control soil temperature during the growing season of cotton to reduce heat stress.

Association The number of cotton bolls was the most influential growth variable on seed cotton yield.
Association Soil salt content had the most significant influence on boll number.
Intervention effect High-frequency irrigation (−10 kPa) was not conducive to reducing soil salinity.
Intervention effect High-frequency irrigation (−10 kPa) was not conducive to increasing boll number.
