Effects of Combined Application of Fermented Chicken Manure and Inorganic Fertilizers on Yield and Quality of Italian Ryegrass
To explored the effects of different proportions of organic fertilizer(OF:Fermented chicken manure)and inorganic fertilizer(IF:Urea)on the yield and feeding qualities of Italian ryegrass.The study included four treatments:control(CK,no fertilizer),100％IF,50％IF+50％OF and 100％OF.The results showed that the yield and nutritional value of Italian ryegrass in the 3 fertilization treatments were significantly higher than that of CK,the 50％IF+50％OF treatment had the high-est plant height,yield,CP and NDF content,and the fresh grass yield reached 26 166.67 kg/hm2.Compared with 100％IF treatment and 100％OF treatment,the fresh grass yield of 50％IF+50％OF treatment was improved by 71％and 55％,respectively.In conclusion,urea combined with fer-mented chicken manure can improve the yield and nutritional value of Italian ryegrass.
