Description
Summary:Emission from coal fired thermal power stations discharges numerous types of gases as pollutant in the ambient air environment, which is causing potential threats to crop production. This study deals with the effects of sulphur dioxide on rice crop (Oryza sativa L.), and yield responses at selected rural sites adjacent to the power station. Eight hour averaged SO sub(2) concentrations were measured at the two stations during the crop period. Physicochemical parameters of the soil and water samples were observed in the crop fields in pre-flowering, flowering as well as post-fowering phases. The uncontrolled area was located by determining the predominant wind direction with the help of wind rose using the meteorological frequency data whereas the controlled area was located upwind to predominant wind direction. The data were constructed and related with the yield responses. There was only a slight reduction in yield of rice crop because of the thermal power plants.
