Jerusalem Artichoke Plots

Jerusalem Artichoke Plots

JART is a perennial specialty vegetable that produces rhizomes, tubers, and woody stalks. The plant is a member of the sunflower family and while it is native to North America, it is not cultivated widely. Jerusalem artichokes are a food staple in some regions of the European Union. Interest in commercially cultivating the plant in Canada is emerging because of the high concentration of inulin and fructose in the tubers. NovaGreen, an Alberta start-up company, has developed a proprietary method of extracting inulin and other neutraceuticals from the JART tubers. Alberta Innovates Technology Futures (AITF) has identified cultivars that are best suited for inulin production.

The College has prepared a segregated field plot to work with NovaGreen to develop commercial agronomic practices to cultivate, and harvest the tubers to maximize inulin yields. Biomass residue samples will be converted to biochar using the College’s pyrolysis equipment. Biochar applied research blends our agriculture, energy, and environmental sciences priorities, as it has applications in soil amendment, land reclamation, greenhouse media, assessing the use of excess production heat for agricultural building heating, and as a wastewater treatment material in place of activated carbon.

The College is working with Novagreen and AITF to develop preliminary best practices for commercial propagation, variety selection, seed vs. tuber cultivation, weed management, seed parameters, and harvest practices for this new commercial crop. Lakeland is working with small field plots to allow for equipment testing and modifications for biomass harvesting. Research outcomes will immediately be transferred to NovaGreen and Battle River Agri-Ventures to develop commercial scale production of JART to enhance inulin production.
