Abstract
A field plot experiment was conducted to study effects of organic fertilizer on yield and yield composition factors of rice.The results showed that the rice yield was much higher when applying 20% pig manure instead of 20% chemical nitrogen fertilizer,applying 10% pig manure decomposed organic fertilizer instead of 10% chemical nitrogen fertilizer or applying 20% biogas fertilizer instead of chemical nitrogen fertilizer,which increased by 103.49%,81.62% and 74.64% than that of non-fertilizer treatment and 38.67%,23.77% and 19.02% than that of pure chemical fertilizer treatment,respectively.
