Abstract:
In Navarra the production of artichokes occurs mainly during the months of March to June, although there is also some production in the fall (October, November), before cultivation stops because of low temperatures. The main zones of artichoke cultivation in Navarra are in the central and southern zones with the Blanca de Tudela variety, reproduced by stalks. The climate of these zones restricts production to these months of the year, since with the arrival of extreme temperatures the quality begins to diminish. Thus, commercialisation becomes unfeasible. To expand the harvest period into the warmer months of summer, one solution could be to transfer cultivation to cooler zones. Therefore, a trial in a zone in the northern Pyrenees was carried out in Navarra (Santesteban, in the Valley of the Baztán), to study the possibility of harvesting artichokes during the months of August and September with a seed origin. The studies included the variety Lorca, A-106 and SUP-3896 during the month of May, soil covered with plastic and irrigated by a drip irrigation system, to analyse production and commercial quality. The primary difference in the trial zone was due to the percentage of plants that didn't enter the production cycle, SUP-3896 being the less productive, whit 17.6 heads per m². Regarding quality, there weren't differences among the varieties observed. The presence of hair at the start of harvesting increased throughout the period of harvesting from (2th of August to the 15th of October), like the hardness of the head.
