Reclamation of a Six-Year-Old Sida Hermaphrodita Field Trial: Experience after Three Years of Agricultural Practice

Short Introductive summary

In this study, the elimination of a six-year-old Sida hermaphrodita (hereafter referred to as Sida) stand for agricultural reclamation was investigated over a period of three years. Crop rotation using maize, wheat, and sugar beet, a catch crop, as well as mechanical-chemical treatments were employed according to agricultural practices. After soil grubbing at the beginning of the experiment and prior to further mechanical-chemical treatments, visible Sida roots were manually removed in addition on half of the former Sida planting area to determine any potential effects of this on total resprouting. Prior to each crop harvest, resprouted Sida plants were counted. The aims of this study were to investigate 1) in how far an elimination of the established Sida stand is possible by means of the applied conventional mechanical-chemical agricultural practices; 2) if resprouted Sida plants impede the productivity of subsequent crops used in this study, i.e., maize, winter wheat, and sugar beet; 3) if resprouted Sida plants hinder harvesting of the following crops; and 4) if Sida shows an invasive nature in the agricultural area of investigation.
