Title

Yield and physiology data of four African crops exposed to varying ozone concentrations, grown in solardomes, UK, 2017

Abstract

Data are presented from an ozone exposure experiment performed on five African crops. The crops (Beans, cowpea, finger millet, pearl millet and wheat) were exposed to three different levels of ozone in the UK CEH Bangor solardomes. Wheat was grown at UK ambient temperature, whereas the solardomes were heated for the other crops to better mimic tropical conditions. The experiment ran from May 2017 to September 2017. The crop plants were grown from seed in pots in solardomes. The aim of the experiment was to investigate the impact of ozone exposure on the crop yield and plant health. The dataset comprises of manually collected data on plant physiology, biomass and yield. In addition the automatically logged data of ozone concentration and meteorological variables in the solardomes are presented. Plant physiology data is stomatal conductance of individual leaves, measured on an ad-hoc basis. The dataset includes the associated data measured by the equipment (relative humidity, leaf temperature, photosynthetically active radiation). Soil moisture of the pots was always measured at the same time, and chlorophyll content of the measured leaf was usually, but not always, determined at the same time. Yield was determined for each plant, in addition to yield-related metrics including mass per bean and 100 grain weight. For finger millet and pearl millet yield is expressed as weight of seed heads and number of seed heads, rather than explicitly as seed weight. The ozone and meteorological dataset is complete, but with some gap-filling for short periods when the computer was not logging data. The work was carried out as part of the NERC funded SUNRISE project (NE/R000131/1). Full details about this dataset can be found at https://doi.org/10.5285/f38beff1-993f-4785-8a97-1de21e3e19c0

Quality and validity

Lineage

Ozone and Meteorological data was automatically logged by PC, with QA to check that data was within appropriate range, outliers checked for plausibility, and gap-filling where necessary. Plant physiology data was collected on an ad-hoc basis from measurements, with QA to check that data was within appropriate range, with outliers checked for plausibility. Plant biomass and yield data was determined experimentally at the end of the experiment, with QA to check that the data was in appropriate range and outliers checked for plausibility. Data were exported into Excel spreadsheets and the exported again as comma separated value (.csv files).
