Abstract: A field experiment was carried out to study the effects of reducing fertilizer on yield of rice, Chugeng 37 was used as material. The paper analyzed the economic benefits under the different treatments. The results showed that Chugeng 37 could get higher yield and higher input-output ratio under the conditions of reducing fertilizer by 30%. The proper amount of fertilizer could not only ensure the high yield, but also could reduce the cost and increase the benefit.

Key words: rice, Chugeng 37, reducing fertilizer and increase benefit, yield
