Abstract
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).

Highlights
Introduction concentrationIncreasing heavy metalMetals being essential component of the concentration in soil increases the environment deposited in the soil uptake of heavy metals by plants depending due the over use of chemical fertilizers, upon the type of soil, plant growth stages pesticides and poor municipal waste and species [3]
Result of vigor index were given in (Table 5) showing that highest vigor index were recorded in treatment T5 while reduce vigor index were noted in treatment T3 (4ppm Cr+3) compared to other treatments, whereas hydroxyl benzoic spray have role to increase seedling vigor index in both varieties of Triticum aestivum L. including TaHabib and Saher (Table 5)
The study was aimed to evaluate the effect of heavy metal (Cr+3) on wheat (Triticum aestivum L.) in response to Hydroxyl benzoic acid (HBA) foliar spray
Summary
Enhancement effect of Hydroxyl Benzoic Acid (HBA) foliar application on growth performance of Triticum aestivum L. (Wheat) under induced chromium toxicity.
