Agronomic practices weed control

Jerusalem artichoke can grow in nutritionally poor soils with minimal cultivation. However, good agronomic practices considerably increase crop productivity. Practices that raise tuber and biomass yields include choice of cultivar, planting date, effective weed control, fertilization, irrigation, and good harvesting procedures. 

One might imagine the extensive development of herbicide resistance in weeds would have led to the development of new tools or agronomic practices to deal with the problem. Unfortunately, this is not the case. A variety of new approaches to weed control can be imagined, but in only a few cases has this translated into practical solutions that can be used to manage the problem in farmers fields. Some strategies proposed many years ago remain theoretical, with no clear examples to demonstrate practical utility.
