Enhancing root lodging resistance of maize with twin plants in wide-narrow rows: a case study

Plant Production Science, 2020
Root lodging is known to reduce the yield and quality of maize, which will be more serious driven by the changes in agriculture such as the higher planting density and the more extreme precipitation events.

Coordination of Density and Nitrogen Fertilization Improves Stalk Lodging Resistance of Strip-Intercropped Maize with Soybeans by Affecting Stalk Quality Traits

Agriculture, 2023
To ensure yield in strip-intercropped maize with soybeans (SM), it is crucial to plant at a density comparable to that of monoculture maize (MM). This requires reducing spacing by more than half, increasing intraspecific competition, and altering stalk ...

Multiple brace root phenotypes promote anchorage and limit root lodging in maize [PDF]

Plant, Cell & Environment, 2021
Abstract Plant mechanical failure (lodging) causes global yield losses of 7%−66% in cereal crops. We have previously shown that the above‐ground nodal roots (brace roots) in maize are critical for anchorage. However, it is unknown how brace root phenotypes vary across genotypes and the functional consequence of this variation.

UAV-Multispectral Based Maize Lodging Stress Assessment with Machine and Deep Learning Methods

Agriculture
Maize lodging is a prevalent stress that can significantly diminish corn yield and quality. Unmanned aerial vehicles (UAVs) remote sensing is a practical means to quickly obtain lodging information at field scale, such as area, severity, and distribution.

Generalizability of a Random Forest-based model of maize lodging built with satellite image data and its application to monitoring and evaluating maize lodging risks

, 2023
Lodging is a common problem in maize production that seriously impacts yield, quality, and the capacity for mechanical harvesting. Evaluation of site-specific lodging risks requires establishment of a method for multi-year monitoring. In this study, spectral images collected by the Sentinel-2 satellite were processed to obtain three types of data: gray-
