In order to evaluate the effects of applying different methods of poultry manure application on maize agronomic traits, an experiment was conducted in a randomized complete block design with three replications in the greenhouse of University of Kurdistan Agriculture during 2019 season. treatments were consisted of no fertilizer (control), solid poultry manure (based on 700 kg ha-1), boiled poultry manure and untreated poultry manure. The effect of poultry manure application on the mean total dry weight, leaf area and total chlorophyll content was significant. The highest mean leaf area, total dry weight as well as total chlorophyll were obtained in boiled extract of poultry manure which had a significant difference with other treatments and had the lowest values for these traits.
