Biochar-Improved Growth and Physiology of <i>Ehretia asperula</i> under Water-Deficit Condition

<i>Ehretia asperula</i>’s physiological responses to growth performance following oak-wood biochar application under water stress conditions (WSC) and no water stress conditions (non-WSC) were investigated in a pot experiment. Biochar (WB) was incorporated into the soil at concentrations...
