Abstract
Heavy metal pollution of water and soil has become a global issue, which extensively effect the major cereal crops and human health in the world. Current study aimed to conduct the role of exogenously applied Hydroxyl Benzoic Acid (HBA) foliar spray on agronomic and physicochemical parameters of two varieties of Triticum aestivum L. i.e. Jhanbaz and Galaxy 2013 under the lead (heavy metal) stress. Leaves of the above plants were treated (after 7, 14, 21 days) with distilled water (control), 2ppm Pb2+ (T1), 2ppm Pb2+ +HBA (T2),4 ppm Pb2+ (T3), and 2ppm Pb2+ +HBA (T4) and response of plants was observed at first, second and third week of the germination. Results of the lead (Pb2+) treatment of 4ppm and 2ppm showed high adverse effect on physiochemical and growth performance. Whereas HBA foliar spray revealed better performance by improving seedling vigorous index, agronomic parameters and percent field capacity under application of lead at 4ppm and 2ppm. This indicated that the toxic effects generated by heavy metal stress were relatively overcome by the application of HBA. However, results exhibited the better growth and physicochemical performance were recorded in Jhanbaz as compared to Galaxy 2013 and recommended variety under induced lead stress (lead).

Highlights
Heavy metal pollution of water and soilInevitably, the use of industrial wastewater supplies has become a major problem in the for agricultural land irrigation has modern world
Pb2+ 2 ppm and 4 ppm Conclusion The effect of heavy metal research can be applied to so many current wheat problems including adverse effect on crop productivity
Keeping in views of these problems the present study was aimed to evaluate the effect of heavy metal on Triticum aestivum L. in response to hydro benzoic acid foliar spray
Summary
The use of industrial wastewater supplies has become a major problem in the for agricultural land irrigation has modern world. Lead is not essential for a relatively high reactions of plant cells but it will remove this metal if it is present in their environment, especially in rural area where it is polluted by automobiles exhausts and in farms, contaminated with fertilizers containing heavy metals as impurities [8]. Heavy metal pollution of soil and water is a global environmental problem [14]. The average concentration of Pb2+ in industrial wastewater was determined by a nuclear absorption spectrophotometer (AAS) and ranged from 2 ppm to 4 ppm. To perform this measurement, a lab specialist pumped 100 ml of dirty water directly into the laboratory [15].
