In spring 2014 enough seed was available to start small field trials for testing. Based on this amount of seed in Holland at AIKC Rusthoeve and in Belgium at the ILVO institute a field trial was planted in order to make a start in making a best practices protocol for the growing of TKS. Results from these first trials were also used to conduct trials for the next season and to get some understanding about the growing of the TKS. These first tests show that higher densities are needed in order to obtain a sufficient amount of roots for a good and competitive crop. Root quality, remainings of leafs and soil tare also appeared to be important issues that contribute to an efficient processing of the roots. During the growing season at the ILVO institute in Belgium samples were frequently taken to monitor the development of the roots and content of inulin and latex over the season.
In 2015 all three members of WP3 received seeds in early spring from KeyGene to start their trials in further testing for the best possible production of TKS in order to conduct a manual for dandelion cultivation. The seeds have been grown in trays to be planted in several plots to do tests on planting density, level of fertilization and harvesting methods. Due to the involvement of the three institutes in Holland, Belgium and the InExCB-KZ institute in Kazakhstan we are able to test under different soil and climatic conditions. Currently all institutes involved are testing TKS planted in flat fields and on beds with various distances in rowing space and density in the row. Next to planting, tests were set up in order to create a more easy and efficient way of sowing of larger surfaces in a short period of time.
