Presently, air pollution becomes apocalypse for living beings (human, animals and crops). Air pollutants have the potential to reduce both nutritional quality and yield of crops. Ten different locations were selected in the vicinity of Thermal Power Plant (TPP) (NTPC Dadri, Uttar Pradesh) to assess the impacts of particulate matter deposition on rice and wheat crops at a different distance within 1-8 km radius. The results indicated that aerial deposition on crop canopy was ranged from 0.85 to 1.88 mg/cm2 in wheat and 0.54 to 1.44 mg/cm2 in rice crop at vegetative stage and flowering stage deposition was 1.08 to 2.20 mg/cm2 of wheat and 0.64 to 2.07 mg/cm2 in rice. We found that effect of air pollutants on crops was maximum at 2-6 km area on the leeward side from NTPC and less impact on the windward side. The particulate matter deposition reduced the photosynthetic rate which leads to decrease in leaf area and transpiration rate in rice and wheat crops and finally had an adverse impact on crop yield. This leads to significant reduction in grain yield of 8.46% and 9.52% in rice and wheat and 11.08% and 12.24% reduction of straw yield in rice and wheat respectively. The maximum yield reduction was observed at Jharcha and Khangoda (most polluted sites) over Akilpur Jagir and Pyawali Tajpur (least polluted sites).
