This study looks at the impacts of concentrations of Nickel (Ni) on the development of tomato plants in contaminated soils, focusing on both physiological and morphological parameters. Soils were contaminated with Ni at concentrations of 0, 15, 30, and 40 mg/kg dry mass of soil. Plant development was monitored at 18, 36, and 54 days after sowing (DAS), with information collected on morphological parameters (plant height, root length, number of leaves, number of fruit, and rate biomass) and physiological parameters (Leaf Area Index, Relative growth Rate and Chlorophyll Content). Results show a clear negative relationship between metal concentration and plant development. At 18 DAS, indeed low concentrations of Ni and altogether anomalous development, due to hormesis prepare with more extreme impacts watched as the presentation period amplified to 36 and 54 DAS. High metal concentrations come about in hindered root and shoot development, decreased chlorophyll substance, and diminished photosynthetic productivity. The discoveries recommend that lower Ni level can invigorate development, but excessive concentrations disturb morphological and physiological forms, leading to development restraint.
