Effects of density and base fertilizer and topdressing on the tuber yield of Jerusalem artichoke
In order to definite the suitable planting density and fertilizer of Jerusalem artichoke in saline and alkaline area of Inner Mongolia, an experiment was conducted with three factors design to study the main yield of Jerusalem artichoke:density, base fertilizer, topdressing. The results calculated by analysis of variance (ANOVA) showed that the main effects of practices on rape yields were density > topdressing > density and base fertilizer and topdressing > base fertilizer and topdressing>density and topdressing>base fertilizer>density and base fertilizer. The main yield is maximal (61 377kg/hm2) when cultivating density was 27 795 plants/hm2,base fertilizer and topdressing amounts were 600 kg/hm2 and 300 kg/hm2. This research will provide scientific reference for the Jerusalem artichoke in the future.
