ANNOUNCEMENTS
In the present study first time field experiment was carried out to assess the impact of air pollutants (SOx, NOx) on the productivity of wheat. At the experimental site four tunnels were installed, wheat crop was exposed to different treatments, i.e. Charcoal filter, Pre filter, SOx combined with NOx and control. The tunnel used in this experiment was 10 meters long, 2 meters wide and 2 meters high. Physiochemical and biochemical estimations were measured according to the standard procedures. In a modern industrialized world, air pollution has become an immensely significant problem. There is mounting evidence to show that how air pollution has wide spread subtle effect on crops productivity. Certain parameters, such as, pH, Electrical conductivity, organic content, leaf area index, photosynthetic rate, dehydrogenase activity, growth parameters were measured and calculated. Study indicated that air pollutants, SOx, NOx could have considerable negative impacts on the productivity of the crop. Results of the study indicates variations in yield parameters, leaf area index, and photosynthetic rate of the wheat. Additional research is needed to confirm the results as well as to better understand the possible impacts under different treatments.
Key words: Wheat, HD-2967, H1-8627, SOx, NOx, Air pollutant
