In recent years, the impact of chromium ions to the agronomic products are quite increased due to their enormous utilization in the industrial sectors. The emerging Cr ions into the soil are gradually entered into the plants and developed an abiotic stress which resulted in the irregular mineral uptake, decreased photosynthetic activity and growth. Different concentrations (10, 25, 50, 75, 100 and 250mgkg-1) of Chromium are exposed to the selected Gossypiumhirsutum (L.) for 90 days. Treated plants selected macro and micronutrients (nitrogen, phosphorous, potassium, calcium, sodium, magnesium, copper and manganese) levels are significantly (P<0.05 & 0.01) reduced as increased concentrations of the Cr concentrations. Our results concluded that Cr exposure for 90 days resulted the decreased mineral uptake mechanism in the tested cotton plants, Gossypium hirsutum L.

Key words : Chromium toxicity, macronutrient, micronutrient, Gossypium hirsutum L.
