Abstract
[Objective] The effect of the amount of N-fertilizer and planting density on potato yield was experimented.[Method] The optimal design of two factors with D saturated was applied to analyze the main efficiency among the factors based on the establishment of mathematical model.[Results] The results showed that the planting density affecting yield was greater than application amount of N-fertilizer.When the amount of N-fertilizer was 212.25-384.90 kg/hm2 and the planting density was from 36 698.70 to 84 040.80 plants/hm2,the theoretical yield of potato was up to about 27 555 kg/hm2.[Conclusion] In the grassland of pasture the best application amount of N-fertilizer was 212.25-384.90 kg/hm2 and the planting density was from 36 698.70 to 84 040.80 plants/hm2.
