An experiment was conducted at RARS, Parwanipur in rice wheat cropping system for two years from 2012 to 2013with nine treatments and four replication with an objective to compare the effect of different sources of organic manure and high analysis chemical fertilizer. Results of the combined analysis revealed that wheat yield and yield attributing parameters such as plant height and panicle length differed significantly with the treatments of the experiment. The highest grain yield (2599 kg ha-1) of wheat was obtained from the plot treated with recommended dose of chemical fertilizer followed by combined application of chemical fertilizer (half of the RDF) and poultry manure @ 10 t ha-1 (2435 kg  ha-1).  Parameters no. of tillers and  test  weight  were non-significant. Unexpected high yield obtained in combined application of vermicompost, FYM and poultry manure.
