Goosegrass (Eleusine indica) density effects on cotton (Gossypium hirsutum)

Xiao-yan MA; Han-wen WU; Wei-li JIANG; et al. Journal of Integrative Agriculture 2015. doi:10.1016/s2095-3119(15)61058-9

Other claims from this paper (10)

Intervention effect Goosegrass at 4 plants per metre of row significantly reduced cotton yield by 20 to 27%.
Intervention effect The regression model predicted a 50% cotton yield loss at 11.6–19.2 goosegrass plants per metre of row.
Intervention effect Boll production was unaffected in the early growing season.
Intervention effect At 4 plants per metre of row, boll numbers per cotton plant fell about 25% late in the growing season.
Intervention effect Cotton boll weight and seed numbers per boll were significantly reduced by 8% at 4 goosegrass plants per metre of row.
Intervention effect Cotton height, stem diameter and sympodial branch number were less affected than yield by goosegrass competition.
Intervention effect Seed index, lint percentage and lint fiber properties were unaffected by weed competition.
Association Intraspecific competition produced density-dependent goosegrass biomass per plant of 142–387 g dry weight at harvest.
Association Goosegrass biomass per square metre tended to increase quadratically with weed density.
Recommendation The authors conclude that effective goosegrass management is needed to protect cotton yield.

Other claims from this paper (3)

Intervention effect Root penetration of defoliated wheat paused for 269 °C days (20 days) after defoliation.
Intervention effect After the pause, wheat root penetration resumed at a rate similar to un-defoliated plants (1.8 mm °C days −1).
Intervention effect Defoliation was associated with reduced water and N uptake of wheat at maturity, especially from deeper soil layers (>2 m).
