BIOCHAR AMENDMENT ALLEVIATES CADMIUM IN CONTAMINATED SOIL AND IMPROVES NUTRIENT UPTAKE IN RICE (Oryza sativa L.)
(ACS Publisher, 2020) Devanand; Pramod Kumar Sharma; Vipin Kumar; Sarvajeet
Cadmium is a toxic metallic element that, if present in high concentrations in soil, poses severe human health risks through intake of contaminated agricultural produces. A pot experiment was conducted in a net house to assess nutrient uptake by rice (Oryza sativa L.) in cadmium-contaminated soil amended with biochar. Six cadmium levels (0, 20, 40, 60, 80 and 100 mg kg-1) and three levels of biochar @ 0, 20 and 40 t ha-1, respectively, were taken. Results indicated that nutrient content and its uptake decreased with increasing levels of soil cadmium. Nutrient content and its uptake were significantly high in soils amended with biochar. Also, the nitrogen and phosphorus contents and their uptake were more in grains; whereas potassium content and its uptake were more in rice straw. Biochar may be used to alleviate the toxic effect of cadmium in cadmium contaminated soils. © 2020, ACS Publisher. All rights reserved.
Effect of biochar augments on various growth attributes of rice (Oryza sativa l.) in cadmium contaminated soil

Anthropic actions like quarrying, transportation, agriculture, industrial waste disposal etc. discharge inorganic pollutants in great concentrations that are toxic to natural ecosystems. Heavy metal like cadmium is a toxic metallic element that poses serious human health hazards through consumption of contaminated agricultural produces when present in high concentrations in soil. To address this problem this experiment was conducted in 2018 to study the effect of biocharon growth, yield and quality of rice (Oryza sativa) in cadmium contaminated soil in the net house. Six cadmium levels (0, 20, 40, 60, 80 and 100 mg/kg) with and without two levels of biochar viz., @ 20 ton/ha and 40 ton/ha respectively were taken as treatment. Plant height, chlorophyll content, panicle length, number of tillers hill-1, productive tillers hill-1, grains panicle-1, harvest index, grain yield, straw yield, protein content and protein yield in rice were recorded. Results of current study indicated that cadmium had negative impact on growth, yield and quality parameters of rice. Growth, yield and quality of rice significantly decreased with increasing doses of cadmium in soil. Results obtained from the experiments also revealed that addition of biochar significantly increased these parameters of rice. In general, the application of biochar has shown the ability to reduce the toxic effect of cadmium on growth, yield and quality of rice. © 2020, Editorial board of Journal of Experimental Biology and Agricultural Sciences.
