N2 - Appropriate management of phosphorus (P) in soil will lead to higher yields and sustainability for sugarcaneproduction. Our study evaluated the importance of differences in root structure and function, and the differentialcomposition of the bacterial community in four sugarcane cultivars, in relation to the efficiency for P uptakeand also to assess changes in soil P with distance from the rhizoplane. Experiments were performed in pot trialsusing a sandy clay loam Ferralsol. In the first experiment, the effect of P application (78.4 mg P kg-1 soil astriplesuperphosphate) on sugarcane cultivars RB92-579; RB85-5156; RB86-7515 and RB96-6928 was investigated.Secondly, we evaluated P rates of 0; 9.8; 19.6; 39.2 and 78.4 mg kg-1 soil using cultivar RB96-6928 which wasshown to be one of the more growth responsive cultivars. The cultivar RB96-6928 exhibited the highest rootdry matter and root surface area, while the bacterial communities found in the rhizosphere of these plants werenot different from other cultivars, as determined by PCR-DGGE. From the P dose-dependent experiment forthis cultivar, optimal plant performance occurred at a P supply up to 38.5 mg P kg-1 soil. Collectively, our resultsindicate that P efficiency in sugarcane was predominantly associated with the generation of high root biomassand surface area.
