After soil analysis, the given data elaborated that the concentration of Cd in soil was stabilized by the amendment from 8.7 mg kg −1 (0%) to 4.2 mg kg −1 (4%). Soil samples were collected from each pot after plant harvesting. Rice plants were harvested after 70 days germination. Standing water condition was kept for rice grown in pots. After transplantation of rice plant, the nitrogenous and phosphatic fertilizers (Urea and DAP) were incorporated at the standard rate. Fourteen days old nursery plants of rice Oryza sativa L. The treatments were arranged in completely randomized design (CRD). All pots were spiked with Cd solution at the concentration of 10 mg kg −1. To conduct the experiment, eight kilograms of air-dried soil were taken in each pot and the amendment biochar was added and mixed properly at different levels like 0%, 1%, 2% and 4% (w/w), respectively. A pot experiment was conducted at Institute of Biotechnology and Genetic Engineering (IBGE), University of Agriculture Peshawar, Pakistan.
