The Agricultural European Policy aims at introducing energy crops in arable fields. While in Northern
and Central Europe several crops were tested and introduced, in Southern European it is necessary to develop agro-
energetic chains for arid arable fields.
For this reason EU funded the Project “Global Process To Improve Cynara cardunculus Exploitation For Energy Ap-
plications” (Biocard) in which CRA-ISMA is responsible for developing mechanisation solutions.
The aim of the paper is to present the research activities conducted to reach the possibility to cut, separate and accu-
mulate only the capitula of Cynara cardunculus, leaving the stalk in the field for a successive harvest.
In Cynara cardunculus it is possible to obtain biomass for energy, seeds for oil and pappus for fine cellulose. If the
whole plant is contemporary harvested, it is not possible to obtain the more valuable products. For this reason the au-
thors designed a capitula harvesting equipment for Cynara cardunculus cultivation.
The results of the tests conducted showed that the prototype was effective in capitula detaching and unloading. The
tests pointed out some aspects that can be improved, especially in relation to the different morphological characteris-
tics that can be found in the cultivation of Cynara cardunculus.
