Abstract:A field experiment was conducted to study the effects of different dosage of coated fertilizer on the yield and nutrients utilization of Xiangzayou ‘1613’. The results showed that coated fertilizer (CF) could improve yield significantly compared with that of the same amount of ordinary fertilizer (OF),the yield of B4 (1 500 kg/hm2 CF usage) reached 2 066.9 kg/hm2, was the highest, followed by B3 (2 250 kg/hm2 CF usage), which was 1 929.9 kg/hm2; There was little difference between A3 (2 250 kg/hm2 OF dosage) and A4 (1 500 kg/hm2 OF dosage) in the yield, which was 1 844.50 and 1 839.40 kg/hm2 respectively, lower than the same amount of CF. The profit of B4 was the greatest, which reached 7 126.4 Yuan/hm2. Compare with A4, the yield of B4 increased 12.37% and the fertilizer usage reduced 11.01%. Moreover, treatment of CF was higher in N, P, K accumulation compared to treatment OF. In general, by taken comprehensive consideration of outputs, profits and other factors, the best dosage for CF was 1 500 kg/hm2.
