Field experiments were conducted to study the effects of the two types of controlled-release fertilizers with different dosages on rice yield, yield components, nutrient absorption and fertilizer utilization in northern Hubei, aiming to provide scientific basis and guidance for the reasonable application of controlled-release fertilizers. The results showed that application of controlled-release fertilizer could significantly increase rice yield. Compared with the treatment without fertilization, application of the mixed coated slow-release fertilizer （MCSF） and humic acid slow-release fertilizer （HASF） increased rice yield by 6.6%~17.3% and 0.7%~11.9%, respectively. Compared with the conventional fertilization treatment, the yield of the MCSF and the HASF treatment increased by 8.4% and 2.5%, respectively. The increase of rice yield in fertilization treatments was mainly due to the increase of effective panicle number. In addition, the MCSF achieved higher yield increase rate than the HASF. The relationship between rice yield and the two kind of controlled-release fertilizer rate was linear-platform. Under the same fertilizer rate, the N, P2O5 and K2O uptake in above ground of the MCSF was significantly higher than that of the HASF. With the increase of fertilizer amount, the apparent recovery efficiency, physiological efficiency, agronomic efficiency and fertilizer contribution rate of the two controlled-release fertilizers increased at first and then decreased, the partial factor productivity of fertilizer decreased gradually. Considering the yield and fertilizer use efficiency, we recommend that the mixed coated slow-release fertilizer should be preferred in the rice production in northern Hubei. The appropriate application amount was 450 kg/hm2, and the rice yield reached 11 420 kg/hm2.
