The potential use of biochar as a carrier for Bradyrhizobium sp. inoculants as provided for lupin (Lupinus angustifolius L.), under drought conditions were evaluated. The survival of BR populations was higher in hydrochar HTC) carrier material than it was in pyrolysis biochar from maize and pyrolysis biochar from wood. A hydrochar-based Bradyrhizobium sp. inoculant significantly enhanced plant growth, N and P uptake, and lupin nodulation under drought conditions. Hydrochar-based formulation of Bradyrhizobium sp. is an effective inoculum carrier providing a promising and practical approach for improving growth and symbiotic performance of lupin under drought conditions.
