INFLUENCE OF THE PLANTING SEASON ON THE CARDOON IN THE AGROCLIMATIC CONDITIONS OF NAVARRE
In Spain the cardoon is a minority crop. Navarre is the main producing area where, in 2008, 356 ha were devoted to its cultivation, and 17,730 t were produced. 80-85% of this production is destined for the areas agroindustry, for canning as well as for freezing. The cardoon is a very important crop within the agri-foodstuff industry in Navarre and its expansion is associated with the growth in the activity of the industry. In Navarre the Verde de Peralta variety population from the Ribera Alta area of Navarre is mostly used. It is characterised by compactness and low stalk fibrousness. This cultivar adapts very well not only to market place consumption, but also to industry. The traditional growing season has been planting in July for harvesting in December, although the expansion of this crop has made it necessary to increase its productive period by programming the harvests by means of different planting dates. This work analyses the agronomic behaviour and industrial suitability of the native Verde de Peralta variety in different planting seasons during two crop years. In the results obtained it can be observed that the lowest production corresponds to the plantings at the end of July and during the first few days of August, due mainly to the fact that a lower weight of cardoon is obtained and not due to the number of commercial units, which is similar in all the cultivation seasons. With later plantings at the end of August the cardoon fails to reach the size suitable for tying up, a cultivation technique used in Navarre for stalk blanching.
