Abstract: In this paper, we had studied the influence of fertilization modes on the economic traits, yield and economic benefits of early rice. Three treatments of soil testing for formulated fertilization, conventional fertilization and control were set to evaluate the effect of fertilization on early rice, which were implemented under field conditions from 2008 to 2012 in 13 counties (cities, districts) of Ji’an City, Jiangxi Province. The results showed that: except the seeding rate of control, the soil testing for fertilizer recommendation reflected more obvious advantages than both conventional fertilization and control. The soil testing for formulated fertilization had the highest yield, averagely reached 7020.2 kg/km2, which was higher than conventional fertilization and control with 463.8 kg/km2 and 2723.8 kg/km2, respectively. The soil testing for formulated fertilization achieved the best economic results, averagely reaching 13308.2 yuan/km2, which increased 849.6 yuan/km2 and 4056.0 yuan/km2 compared with conventional fertilization and control. The results demonstrated that soil testing for formulated fertilization was the best fertilization mode, and was more suitable for the local promotion and application.
