Countries around the world are experiencing increased levels of air
pollution as a result of rapid increase in energy consumption and
motor vehicle uses, a product of rapid population and economic
growth. Agricultural lands adjacent to urban areas (peri- urban)
are increasingly exposed to air pollutants of urban origin, which
reduce the crop production. Crop production is highly dependent on
environmental conditions, among which air quality is an
anthropogenic factor. The air quality of the study site is under
threat because concentrations of NO2, SO2 and O3 increased in
successive years of observation. Air pollutant concentration
present in air has enough potential to cause damage to agricultural
crops (both cereal and pulse crops). An increment in fertilizer
dose, one and half times of recommended was most suitable to
overcome the damage caused due to air pollutants as it
significantly increased photosynthetic pigment, plant height,
biomass accumulation and yield of both the crop plants and
significantly reduced peroxidase activity and phenol content. On
individual nutrient basis nitrogen was most responsive to minimize
negative effects of air pollutants.
