Spain is the second artichoke producing country in the world, and its production is based, almost exclusively, on the clonal propagation variety ‘Blanca de Tudela’. In Navarre, where the ‘Blanca de Tudela’ originates from, the most usual planting season is the first ten days of August and the plant spends the winter in rosette form without producing heads. However, there are also some early plantings which produce in autumn. Autumn earliness is a very important aspect for this crop reaching the highest price by head on the fresh market during this time. In the main Spanish producing zones of Murcia and the Valencian Community (region), which enjoy a temperate climate, there is a tendency to bring the planting dates forward in order to achieve earlier production, although other cultivation techniques are currently being researched. This piece of work analyses the influence of the planting season on the root-taking, earliness and yield of the ‘Blanca de Tudela’ variety in three planting periods (from early July to the end of August), cultivated annually using drip irrigation over two crop years. It has been observed that when the planting date is brought forward, production in autumn is achieved, but in the end total commercial production is greater in the later planting at the end of August, but without significant differences between seasons. Winter frosts have an increased negative influence on production in the early plantings as they mostly affected the plants in which harvesting had begun, thus delaying harvesting in spring with respect to the later plantings.
