Heavy metals are toxic to plants even at low concentration, resulting in growth and total biomass reduction. Present research was intended to assess the effect of induced chromium toxicity on growth and performance of wheat varieties (Ta-Habib and Sahar) extensively growing in Peshawar region, Khyber Pakhtunkhwa surrounded by industrial area, adding 2-4 ppm Cr+3 in the form of effluents to irrigation water. The study also focused on the enhancement effect of Hydroxyl benzoic acid (HBA) foliar spray under chromium toxicity wheat plant. Highest amplitude of agronomic characteristics, germination percentage and vigor index was observed in Ta-Habib indicated tolerant variety as compared to variety Sahar which has been proved by the hyper accumulation of Cr+3 in the mentioned variety. It was reported that treatments T1 (2ppm Cr+3) and T3 (4ppm Cr+3) showed adverse effects which were mitigated by the foliar application of Hydroxyl benzoic acid (HBA).
