| Abstract: | To determine suitable application of nitrogen and potassium fertilizer in potato for the Rice-Rice-Potato triple cropping system in Southeast Fujian, the experiment of nitrogen and potassium levels was conducted in Longhai. The results showed that there was a parabola relationship between potato yield and the application rate of N, K fertilizer. The economic application amount of N and P fertilizer for potato were 16kg and 13.4kg as the target yield of 2500kg per 667m 2 , and the ratio of N to K was 1：0.84. |
| Keywords: | rice-rice-potato triple cropping system potato N P K fertilizer application rate |
