Title

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%.
Intervention effect The grain yield reduction from reproductive-stage drought was greater than that from vegetative-stage drought.
Association The decrease in kernels per ear was associated with the decrease in grain yield (r2 = 0.88, P < 0.001).
Recommendation Guaranteeing water supply for maize during the reproductive stage is crucially important to avoid yield loss.

Other claims from this paper (6)

Intervention effect For irrigated cotton, three years in and one year out is projected to give the best lint yield.
Intervention effect Cotton yields are projected to decrease under changing climate at most locations across crop sequences.
