Residual application of P-enriched poultry manure with P-levels significantly increased the yield of bengal gram.  The increase in yield over no organic manures was 118.92 per cent.  Residual application of P-enriched poultry manure alongwith HRDF-P has produced yield equivalent to that of RDF-P alone.  Higher uptake of phosphorus by bengal gram was registered due to increased availability of phosphorus.
