Comparative efficacy of farmyard manure(FYM), vermicompost (VC), biogas slurry(BS) and poultry manure (PM) with and without P-enrichment on zinc availability to maize and bengal gram was evaluated in a vertisol under irrigated condition. On the basis of the uptake of zinc by maize and bengal gram, the performance of different organic amendments in maize followed the trend; PM>BS=FYM=VC and in bengal gram; PM>BS>FYM=VC. Substantial buildup of available zinc in soil was observed due to the application of above amendments.
