A japonica rice cultivar Yangjing 4038 was used and four kinds of organic fertilizers including maize straw (MS), compost made from maize straw (MC), maize residue of methanegenerating (MR), and black carbon made from maize straw (BC) were applied to the paddy field before rice transplanting, with no organic fertilizer application as control (CK). Effects of each organic fertilizer on rice grain yield and emissions of greenhouse gases from paddy field were investigated under both no nitrogen (N) application (0N) and sitespecific N management (SSNM). The results showed that, under either 0N or SSNM, application of MS, MC, or MR significantly increased grain yield when compared with CK. The MS treatment showed the highest grain yield and agronomic N use efficiency (kg/kg) among the all organic fertilizer treatments. There was no significant difference in grain yield between the BC and CK. The emission of methane (CH4), carbon dioxide (CO2), or nitrous oxide (N2O) from the field exhibited a similar trend during the whole rice growing season under all the organic fertilizer treatments. Application of each organic fertilizer significantly increased the emission of each greenhouse gas and global warming potential (GWP) except the N2O emission which was not increased under the BC treatment, relative to that under CK. Under the same organic fertilizer treatment, SSNM increased emissions of all the greenhouse gases and GWP, whereas decreased GWP per unit grain yield (amount of GWP/grain yield), when compared with 0N. The results indicate that application of organic fertilizers, such as MS, MC, and MR, could not only increase grain yield, but also enhance emissions of greenhouse gases from the paddy field. Both higher grain yield and higher environmental efficiency would be achieved by the adoption of SSNM and the application of MR fertilizer.
