Effects of P fertilization on (A) cassava root fresh weight (kg plant⁻¹) and (B) AMF colonization (% root length) of AMF inoculated treatments at each of the three locations and in the two cassava varieties grown at each location. Error bars represent ±SE. Means with different letters are significantly different at p < 0.05 according to a Games-Howell post hoc test. The statistical test represents a comparison among P treatments within each cassava variety at each location. Tz, Tanzania; Ke, Kenya.
