Abstract: In order to study effect of organic fertilizer on yield and quality of continuous cropping eggplant，compared with application of chemical fertilizer，pig manure，chicken manure and sheep manure were set as control to study change characteristics of quality and yield of eggplant.Results showed that application of organic fertilizer could affect quality and yield of eggplant in different degrees.Soluble sugar content of eggplant was the highest under pig manure treatment at each sampling date.On June 20 and July 10，contents of vitamin C and free amino acids were the highest and nitrate content was the lowest.On July 30，the contents of vitamin C and free amino acids were the highest and nitrate was the lowest.The highest yield and lowest incidence rate and disease incidence were found in chicken manure.Chicken manure could not only increase yield of eggplant but also significantly reduce incidence rate of Verticillium wilt，which was a high yield and high efficiency fertilization mode，and had a good application prospect in eggplant production.
