Effects of variety,planting density and fertilization method on the yield of sweet potato
Abstract：Effect of different varieties,planting density and fertilization method on the yield of sweet potato was studied by using orthogonal design method.The results showed that: varieties were the main factor affecting sweet potato yield,then cultural density and the fertilization method was a secondary factor.Meanwhile,the maximum tuber yield could be obtained when Longshu1 and Jinshan57 were chosen and planting density,fertilization rates of N,P2O5 and K2O were 4000 plant/667m2(60,000 plant/hm2),11.5 kg/667m2(172.5 kg/hm2),53 kg/667m2(795 kg/hm2) and 15 kg/667m2(225 kg/hm2) respectively.
