The whole harvest cultivation method for one-year-old asparagus plants (new cultivation method) does not require occupying the field for a long time, as it shortens the growing period, compared with conventional methods. In this case, the harvest time is until May or June of the year following planting. Therefore, it is necessary to consider appropriate succeeding crops. This study examined the chemical properties of soil and allelopathic activity of the field after the harvesting of asparagus produced by the new cultivation method (after, the new cultivation method). We also planted various succeeding crops in the ridges and furrows of the field after the new cultivation method, and compared their growth and yields. The chemical properties of soil and allelopathic activity were within ranges that did not negatively affect each succeeding crop. Furthermore, among these crops, the yields of those in ridges and furrows of the field after the new cultivation method were equivalent, excluding cherry tomatoes, being similar to the mean yield in Japan. Regarding the suitability of succeeding crops for the whole harvest cultivation method for one year-old plants, crops other than asparagus can be cultivated in fields after harvesting by this method.
