Results showed that fertilizer treatments had significant effect on large size tubers yield and large size tubers number at 1% probability level and on medium size tubers yield, total tubers yield, medium size tubers number, total number of tubers and tubers nitrate percentage at 5% probability level. Based on the results obtained, the most effective treatments on total yield of potato were vermicompost cow+ sheep manure, and chicken manure, respectively. The total yield of potato by application of vermicompost was 1.3% more than the yield by application of cow +sheep manure and 20.6% more than the yield by application of chicken manure. The results showed that application of vermicompost was not only economic and effective on potato yield, but also was better than other treatments for human health and environmental pollution.                                                                                                      Keywords:Chicken manure, Vermicompost, Manure, Potato
