| Abstract:
Field experiments were carried out from 1997 to 2000 in Tarquinia, Central Italy, to compare yield and earliness of different artichoke varieties (Grato 1, Grato 2, Castellammare, Campagnano and C3) under conventional and low-input farming practices. The treatments were arranged in a split-plot design where farming system was used as main plot, and cultivar was used as split-plot. Each treatment had four replications. Significant differences were found among cultivars alone. Head weight and diameter of Grato 2 were higher than those obtained by Grato 1, Castellammare, Campagnano and C3 varieties. Number of 1st order heads per plant was the highest in Grato 2, while Grato 1, Campagnano, and Castellammare had the highest number of 2nd order heads. Highest precocity was expressed by C3 cultivar. Characters studied were not significantly affected by the farming systems and its interaction with cultivars. The non significant differences between conventional and low input system suggested that sustained artichoke yield can be achieved by using limited chemical input. | |
