Ozone Exposure Effects on Bean and Sweet Potato Yield and Physiology, UK 2019

June to October 2019 data from a solardome experiment on two African crops (beans and sweet potato) exposed to three ozone levels. The dataset combines manually collected plant physiology, biomass, and yield measurements with automatically logged ozone concentration and meteorological variables. The work was part of the NERC-funded SUNRISE project.

Use Cases

• Model crop yield response to varying ozone concentration levels using manually collected yield data.
• Analyze correlations between stomatal conductance measurements and concurrent meteorological variables like relative humidity and photosynthetically active radiation.
• Investigate plant health by examining relationships between chlorophyll content, leaf temperature, and soil moisture measurements.
• Assess the impact of ozone exposure on biomass accumulation for bean and sweet potato plants grown from seed or plug plants.

Strengths

• Includes data for two distinct crop types (beans and sweet potato) across three controlled ozone exposure levels.
• Combines manually collected plant physiology data with a complete, automatically logged ozone and meteorological dataset.
• Experiment conducted under controlled solardome conditions from June to October 2019.

Limitations

• Plant physiology measurements like stomatal conductance and chlorophyll content were collected on an ad-hoc, not systematic, basis.
• The ozone and meteorological data required gap-filling for short periods when the computer was not logging.
• Limited geographic scope to a single solardome facility in the UK, not field conditions.
