Title

Comparison of Short Staple Planting Dates

C. R. Farr UA Campus Repository (The University of Arizona) 1976

Other claims from this paper (6)

Association Boll size was smaller for the last two planting dates.
Observation Five-lock bolls were larger than four-lock bolls.
Association Boll numbers did not consistently decline as planting was delayed.
Association Boll size did not consistently decline as planting was delayed.
Observation The June 15 planting showed undue moisture stress.
Intervention effect Early frost killed many late bolls and reduced yield below expectation.

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.
Mechanism The decrease in kernels per ear largely caused the decrease in maize grain yield.
Recommendation Guaranteeing water supply for maize during the reproductive stage is crucially important to avoid yield loss.
