Drought stress has a major abiotic impact on the symbiotic performance of legumes,
inhibiting plant growth and nodulation. We evaluated the potential use of biochar as a carrier
for Bradyrhizobium sp. inoculants as provided for lupin (Lupinus angustifolius L.), and to
determine the response of lupin to the biochar-based inocula of Bradyrhizobium sp.(BR) in
pot experiments, under irrigated and drought conditions. The survival of BR populations was
higher in HTC-char carrier material than it was in pyrolysis biochar from maize (MBC) and …
