Conference paper


Representative strains of Azospirillum spp. were isolated from roots of plants grown in Gassim, Saudi Arabia. They were identified as A. brasilense. A liquid inoculum prepared from a mixture of 3 potent strains was used to inoculate seeds of 2 wheat cultivars. A field trial was executed to compare biofertilization with azospirilla against N-fertilization. Significant responses to inoculation in the presence of a limited supply of N was obtained particularly for cv. West-Breed. The root biomass was very significantly increased and there were substantial increases in straw yield. Seed yield was 31.5 % higher than in uninoculated plants receiving a limited dose of N.
