Nitrogen oxide and ozone concentrations, pollinator visitation frequencies and yield metrics of Brassica nigra in fumigation rings, Sonning, UK, 2018-2019

The dataset contains concentrations of nitrogen oxides (NO and NO2, collectively NOx) and ozone (O3), frequencies of insect pollinators and flower visits and yield metrics of Brassica nigra plants collected from within eight field-based fumigation rings located at the University of Reading's Sonning Farm, UK.
