Differential responses of maize yield to drought at vegetative and reproductive stages

MI Na; Fu CAI; Yushu ZHANG; et al. Plant Soil and Environment 2018. doi:10.17221/141/2018-pse

Other claims from this paper (6)

Intervention effect Progressive drought significantly reduced maize grain yield during either the vegetative or the reproductive stage.
Intervention effect Reproductive-stage progressive drought reduced grain yield by 41.6-46.6%.
Intervention effect Vegetative-stage progressive drought reduced grain yield by 18.6-26.2%.

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 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.
