Abstract: In this paper, we had studied the influence of fertilization modes on the economic traits, yield and economic benefits of late rice. Three treatments of soil testing for formula fertilization, conventional fertilization and blank no fertilizer were set to evaluate the effect of fertilization on late 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 treatments reflected more obvious advantages than both conventional fertilization and blank treatment. The soil testing for formula fertilization had the highest yield, averagely reached 7478.6 kg/hm2, which was higher than conventional fertilization and control with 547.0 kg/hm2 and 2899.8 kg/hm2, respectively. The soil testing for formula fertilization achieved the best economic results, averagely reaching 15236.2 yuan/hm2, which increased 1061.8 yuan/hm2 and 4724.8 yuan/hm2 compared with conventional fertilization and control. The results demonstrated that soil testing for formula fertilization was the best fertilization mode, and was more suitable for the local promotion and application in the present experimental conditions.
