Evaluation of Different Nickel Doses on Soil Nutritional Aspects and Seedlings Growth of Canola

Abstract

Heavy metals found in industrial waste, particularly nickel, have the potential to impact soil fertility as well as crop yields. The primary goal of this study was to determine which specific nickel dosage had a detrimental impact on soil properties as well as canola production. The CRD approach was used to design the experiment with three biological replications. The Ni dose @ 0, 1000 µM by 200 was applied to soil. The nickel at 1000 µM increased soil pH and Ec by 5.35% and 391.85% as compared to control. The increase in soil pH and Ec due to nickel at 1000 µM decreased the soil macronutrients including nitrogen, phosphorus and potassium by 82%, 79.57% and 80.04% and micronutrients including copper, zinc and magnesium by 84.72%, 55.35% and 91.28% as compared to control. The canola seedlings growth aspects including shoot/ root length, fresh weight and dry weight were decreased by 79.95%/61.94%, 61.02%/97.02% and 69.85%/96.99% in response to nickel at 1000 µMover control. The correlation analysis clearly indicated the soil-plant interaction under toxicity of highest dose of nickel. Future research work is needed on mitigation approaches for sustainable agriculture practices.
