Comparison of Nitrogenase Regulation in A. Brasilense, A. Lipoferum, and A. Amazonense,te, histidine or proline nitrogen fixation in A. brasilense strains was only slightly reduced, whereas in .. . and .. . strains these amino acids almost completely abolished nitrogen fixation. Differences in the levels of ammonium assimilatory enzymes were found. After the addition of ammonium chlor

Evaluation of Nitrogen Fixation in Sorghum Cultivars Inoculated with Different Strains of Azospirilwith .N was used and the applied N-fertilizer was labelled with equal N. % excess. Four strains of . spp., isolated from sorghum roots were used as inoculants. The strains were resistant against certain antibiotics, so that their identification was possible upon reisolation.

Possible Contribution of Azospirillum spp. to the Nutritional Status of Wheat Plants Grown in Sandyed 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. Wes
