| Abstract: | During 19941997, the rate of fertilizer application, plant density and cutting time for sweetpotato Jin 3 were studied. The result indicated that the optimum rate of fertilizer application was as follows, N 113.1138.6kg/hm2, P2O5 116.2512855kg/hm2, K2O 36814359kg/hm2, the proper plant density was 52 500 plants/hm2, and the proper cutting time was April, 25 or so. Sweetpotato yield could reach 45 000kg/hm2 or so by means of this cultivation technique. |
