Optimum Application Level of Liquid Pig Manure for Increasing Green Manure Crop Yield

The effects of liquid pig manure (LPM) on the yield and nutrient supply of green manure crops, such as hairy vetch alone and hairy vetch + rye mixture, were investigated. We used three treatments: no-fertilizer (NF); LPM, 4.0 t 10 a ). The green manure crops, namely, Vicia villosa Roth. (hairy vetch) and Secale cereale L. (rye). were sown on March 11 and harvested on June 24, 2014. Yield of green manure crops significantly increased in hairy vetch + rye mixture plot compared with the hairy vetch alone plot. In hairy vetch alone plot, yield of green manure crops was increased by application of LPM and CF, but there were no significant differences. Yield of green manure crops in hairy vetch + rye fresh mixture plot significantly increased by the LPM and CF treatments, but no difference was noted between the LPM and CF treatments. Nitrogen supply by the green manure crops was higher in hairy vetch + rye mixture plot than hairy vetch alone plot. However, there was no significant difference. Phosphorus and potassium supply significantly increased in hairy vetch + rye mixture plot compared with hairy vetch alone plot. By treating LPM and CF, the nitrogen, phosphorus and potassium supply were higher than those in no fertilizer. In conclusion, LPM could replace CF. When planting green manure crops, the hairy vetch + rye mixture was more effective than hairy vetch alone to effectively use green manure crops.
