| Abstract: | Yield and economic benefit of Sankang 8,a sweet potato variety with virus-free,was tested under different planting density by the field experiment method to determine the optimum planting density and provide a basis for its popularization.The results showed that the yield could be up to 2 577.9 kg/667m2 under the density of 4 600 plants/667m2 and its input/output ratio was up to 2.37.Therefore,the optimum planting density for Sankang 8 should be 4 600 plants/667m2. |
