Abstract
Influence of interplanted species on N and P resorption efficiencies of companion species was studied in mixed plantations of various species combinations raised for revegetation of coal mine spoil. The species combinations were legume: legume, legume: non-legume and non-legume: non-legume. The interplanted species were found to alter the N and P resorption efficiences of companion species in all combinations. In leguminous species the N and P resorption efficiencies dropped with increase in foliar N and P concentration, whereas in non-leguminous species the N and P resorption efficiencies increased with increase in foliar N and P concentration. Across all species, the N resorption was found independent of foliar N status, while the P resorption efficiency increased with increase in foliar P concentration.
