Abstract
Varietal differences in P absorption and utilization by sugarcane were studied with the objective of selecting phosphorus efficient varieties which can perform well under conditions of low soil phosphorus availability and at low P application rates. Sugarcane varieties differed significantly in dry matter, cane and sugar yields, P-concentration and P-uptake. Based on the cane and sugar yield phosphorus efficiency indices, varieties were classified as ‘P efficient’ and ‘P-non-efficient’. Phosphorus efficient varieties had low P-concentrations and produced higher dry matter per unit P absorbed.
