Not AvailableIn an experiment with a test crop of chickpea during rabi, 1999-2000 the influence of P, S and Fe on the uptake of P and S was assessed using isotopic tracers (32 P and 35 S). It was found that the dry matter production increased by the application of phosphorus at 60 kg P 2 O 5 ha-1 in both with and without Rhizobium inoculation and the combined application of P and Fe produced higher dry matter of both shoot and roots with inoculation. An assessment of the radioassay of applied phosphate and sulphate showed lower values of per cent derived from fertilizer in respect of both P and S. However, the values of phosphorus derived from fertilizer (Pdff) were comparatively higher due to combined application of P, S and Fe and those for sulphur due to phosphorus and sulphur only. The contribution of phosphorus from soil was more due to combined application of phosphorus and sulphur against the inoculationNot Availabl
