Influence of Organic Manures and Synthetic Fertilizers on Nutrient Uptake and Yield of Fodder Maize

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Chennai, during rabi season 2019 - 2020 to study influence organic manures and synthetic fertilizers on nutrient uptake green fodder yield maize (Zea mays L.). An laid out with two factors three replications. Four manure treatments in main-plots viz., no manure, farm yard (25 t ha-1), vermicompost (12 ha-1) poultry four fertilizer subplots No fertilizer, 125% RDF, 100% 75% RDF. The recommended dose (RDF) for is 60 kg N ha-1: 40 P2O5 20 K2O ha-1. were applied as per equivalent basis inorganic recommendation. results revealed that application nutrients through @ 12 ha-1 resulted higher plant Nitrogen (112.2 phosphorus ( 19.26 potassium 117.7 followed by 25 basis. Concerning fertilizers, nitrogen, phosphorous, (104.9, 18.9, 108.54 Kg N, P, K, respectively). About yield, highest dry recorded under treatment combination along RDF 31.84 5.19 DAS,
