Abstract: In this paper, effect of different planting densities on yield and agronomic characters of peanut cv.‘Quanhua 27’ was studied. The results showed that suitable planting density of‘Quanhua 27’ was 20 200 grains per 667 m², under this condition, the yield composition factors were coordinative. The yield per 667 m² of pod was the highest, reached 279.0 kg.
