Corn grain yield responses to tillage systems and plant densities

OsMPH1 regulates plant height and improves grain yield in rice

Plant height is a major trait affecting yield potential in rice. Using a large-scale hybrid transcription factor approach, we identified the novel MYB-like transcription factor OsMPH1 (MYB-like gene of Plant Height 1), which is involved in the regulation of plant height in rice. Overexpression of OsMPH1 leads to increases of plant height and grain yield in rice, while knockdown of OsMPH1 leads ...

Determination of Early Stage Corn Plant Height Using Stereo-vision

Periodic measurements of plant height could be used to calculate growth rate and have potential for characterizing spatial variation of plant response to inputs and field conditions. A corn plant height measurement system using stereo machine vision was developed. A test apparatus was developed, which consisted of an x-y translating sensor platform with a CCD camera and an imaging stage for cam...

Use of corn height measured with an acoustic sensor improves yield estimation with ground based active optical sensors

Corn height measured manually has shown promising results in improving the relationship between active-optical (AO) sensor readings and crop yield. Manual measurement of corn height is not practical in US commercial corn production, so an alternative automatic method must be found in order to capture the benefit of including canopy height into in-season yield estimates and from there into in-se...
