Abstract

---

Three rice (Oryza sativa L.) varieties (Basmati-Pak, Basmati-370 and IRRI-9) of Pakistan were grown for their entire life cycle in open top field chambers to investigate the impacts of ambient ozone (O3), nitrogen dioxide (NO2), and sulphur dioxide (SO2) on the biomass, growth physiology, and yield. The treatments were charcoal filtered air (FA), unfiltered air (UFA) and ambient air (AA). O3, NO2, and SO2 concentrations recorded at the experimental site were 75
