Economic sustainability of today’s artichoke cultivation aims, to some extent,to process innovation. Among the various steps of the productive chain, harvestingstill done by hand, absorbs a large need of labor, resulting in the most expensive one.In order to develop mechanization of some cropping steps and with the aim ofexploiting secondary heads production for industrial process, experiments werecarried out in an area highly representative for globe artichoke cultivation (Niscemi,Sicily, Italy). The cultivar ‘Violet de Provence’ was grown using three different plantdensities 0.6, 0.9 and 1.2 plant m-2. At 0.6 and 0.9 plant m-2 were used single row,while at 1.2 plant m-2 were used twin rows. Results showed solutions which allow tointroduce mechanical harvest, able to reduce production costs, and to increase yield.Among the limits to overcome contemporary maturation of the heads is highlighted.With the highest plant density valid results were achieved for the purpose of processinnovation. However, the adoption of alternative plant density instead of thetraditional one should be assessed in relation to an increase of costs for cropmanagements, mainly due to the higher number of propagation material perhectare, energy inputs and other economic aspects. In order to optimize theinnovation should be carefully assessed cases where the individual and take accountof the cost advantages also in consideration of possible differences due to damage ofthe product during the stages of harvesting.
