In managed drought stress trials, it is critical to achieve the required level of drought at the target crop stage in order to generate high-quality, repeatable trial data.
The three key factors to be taken account are:
- When to stop irrigation to impose the desired level of drought stress at the targeted crop stage
- How to track drought progress in the field, in terms of stress severity and uniformity
- When to resume irrigation to terminate stress and achieve the desired level of drought, in terms of intensity and duration.
This manual presents a standardized, field-based precision phenotyping protocol for the quantitative management of reproductive-stage drought stress in maize.
The manual covers the various steps involved in managed drought stress field-based precision phenotyping.
The same principles can by modified for the case of other crops and / or crop stage.
