Determination of abundance and symbiotic effectiveness of native rhizobia nodulating soybean and other legumes in Rwanda.

While the intercept was highly significant, estimates of the remaining variables were significantly related to rhizobia cell number ( p < .05). 3.4 Correlations between soil's physico‐chemical properties and Rhizobia cell number The Pearson's correlation coefficients between soil's physico‐chemical properties and the total number of nodulated units per unit per g of soil rhizobia cell number are presented in Table 4 .
