Abstract：In order to explore a reasonable single-seed sowing mode for the new peanut variety Shanghua 4,the experiment adopted split-spot design and studied the effects of different plant density on characteris-tic and yield in peanut single-seed and double-seed sowing modes. The results showed that,with the in-creasing of sowing density,yield and pod number of per plant showed a decreasing trend,the full-pod rate and shelling percentage showed a increasing trend. The pod yield had no significant difference between the single-seed and double-seed sowing modes. The difference of peanut pod yield was significant among different plant densities. In the planting density of 22. 50 × 104 caves/ha,pod yields of single-seed and double-seed modes both reached the highest,6 991. 5 kg/ha and 6 758. 4 kg/ha,respectively,with no sig-nificant difference. In summary, single-seed sowing with planting density of 22. 50 × 104 caves/ha was able to achieve the target yield and increase economic benefits of Shanghua 4 .
