Abstract:
This research aims to evaluate the effect of biochar types in planting media containing the heavy metals Pb, Cu and Hg on the growth, yield and quality of rice (Oryza sativa L.). The research was carried out at the Experimental Garden of the Faculty of Agriculture, Udayana University from May to October 2024. The method used was a one-factor randomized block design (RAK) with three replications and three treatment levels, namely straw and rice husk biochar (Br), shell and coir biochar. coconut (Bc), and lignohumic biochar (Bl). Biochar Bc has been proven to be able to increase the weight of total grain and grain content, which shows that the use of this biochar contributes positively to rice yields. These findings emphasize the importance of choosing the right biochar raw material to increase rice productivity on contaminated land. It is hoped that this research can contribute to the management of agricultural land affected by heavy metal pollution.
