Effects of application of Chinese milk vetch and fertilizer onrice yield and soil nutrient content

A field experiment was conducted to determine the effects of application of Chinese milk vetch and fertilizer on rice yield and soil nutrient content in 2009 for understanding the possibility of the same amount N and K from Chinese milk vetch instead of the same amount N and K from chemical fertilizer. This study showed that application of Chinese milk vetch and chemical fertilizer increased the rice yield and the soil organic matter, available N, P and K content. The treatment with 60% chemical N and K fertilizer and 40% Chinese milk vetch performed well, and it increased the rice yield by 28.7% and the soil organic matter, available N, P and K content by 2.1%, 9.3%, 12.7% and 15.5%, respectively.
