| Abstract: | A field experiment was conducted to compare local chickpea (Giza 2) and its recently developed cultivar L3. The two genotypes were examined for biological dinitrogen fixation and P uptake as enhanced by inoculation withRhizobium (Rh) and/or arbuscular mycorrhiza (AM). Significant increase in dry mass was obtained by biological inoculation. Soil chemical and physical properties have a significant effect on the ability of the two genotypes to fix nitrogen on their P uptake and N content. Growth of the local genotype (G2) was pronounced in sandy loam soil as compared with the sandy one. |
