Background: Various human activities, such as industrialization, modern farming methods, and mining increase the concentration of heavy metals in air, water and soil. Heavy metal poisoning of soil results in a number of environmental issues and has deleterious effects on both plants and animals. Therefore, the purpose of this study was to investigate the effects of Arsenite (As) and As+ Serine (Ser) on growth and biochemical components in the early growth stages of Abelmoschus esculentus (L.) Moench, Triticum aestivum L., and Zea mays L. (selected crops).

Methods: Pot experiments were carried out at completely random manner, with 10-12 seeds grown in each pot with three replicates. Seeds and seedlings in pots treated with different concentrations of As and As+Ser. After a 21-days of germination period, we gathered the growth-related parameters (root number, root length, shoot length, and leaf number) and conducted a biochemical analysis.

Results: The growth of selected plants was adversely impacted by Arsenic stress, whereas the detrimental impact was minimal after treatments with Serine. Compression of the selected crops showed that Abelmoschus esculentus L. had the most detrimental impact on agronomic parameters. Biochemical constituents such Chlorophyll “a” “b”, Total-chlorophyll (Photosynthetic pigments), protein and carotenoid contents formation were reduced at individual treatments of As (25, 50, 75 and 100pmm) compared to As+Ser and control treatment, while the proline contents were increased considerably at treatment 100 ppm (As) of the selected crops.

Conclusion: The results showed that As had a greater negative impact on growth and biochemical constituents, whereas Ser had a reduced adverse impact on selected crops. Abelmoschus esculentusL. had a higher sensitivity compared to other selected crops.
