Field experiment was conducted to assess the efficiency of selected organic liquid manures on growth and yield of amaranthus. The liquid manures were prepared by soaking composite organic manures in water (1:5 ratio), collecting the extract seven days after soaking and enriching the same with PGPR addition. Among the combinations, the extracts of composite manure prepared by mixing groundnut cake, neem cake and poultry manure (in 1:0.5:0.5 ratio), groundnut cake, vermicompost and poultry manure (in
1:0.5:0.5 ratio), and groundnut cake and poultry manure (in 1:1 ratio) recorded high nitrogen content (0.56-0.78%). Foliar application of these liquid manures as substitute to nitrogen for top dressing in amaranthus enhanced plant height, number of leaves per plant, crop yield and vitamin C content.
