Study on optimal technique for high yield of purple flesh sweetpotato in Chongqing
The effects of fertilization, planting density and variety on yield of purple flesh sweetpotato were studied by orthogonal test of L9 (34). The results showed that the yield of Wanzi 56 was highest a-mong 3 purple flesh cultivars on conditions that planting density was 75 000 plants per hectare,and fertilization was 300 kg per hectare. The influence of planting density for yield of purple flesh sweetpotato was higher than that of fertilization.
