The aim of this research is to study accumulation of Chromium along with nutrients and its effect on the growth of Paddy plant (Oryza sativa L). Thus, paddy seedlings grown in petriplates lined with filter paper undergoing, different treatments of Cr (0, 2.5, 5, 10, 25, 50, 75, 100 and 200 mg/L). After one week seedlings were removed and morphological parameters like root length, shoot length and dry weight of plants and accumulation of nutrients along with Cr content were determined. The results indicated that the concentrations more than 100 mg/L chromium cause the reduction of morphological parameters in the treatment plants rather than control plant and Cr addition in the cultures caused enhancement of chromium content paddy seedlings. Similarly nutrient accumulation also affected by increasing concentrations of chromium.
