%X a trial was established using three month old asparagus (asparagus officinalis l.) plants in a volcanic soil at chill¨¢n (36¡ã32£¿ s; 71¡ã55£¿ w). experimental design was randomized complete blocks with four replicates. plots had four 6m long rows of plants. distance between rows was 1.5 m and in-row 0.2 m. the evaluated cultivars were: £¿atlas£¿, £¿grande£¿ and £¿apollo£¿ from asparagus seeds and transplants (california), £¿jersey giant£¿, £¿jersey gem£¿, £¿jersey general£¿, £¿jersey king£¿, £¿jersey knight£¿ and £¿jersey supreme£¿ from jersey asparagus farms (new jersey), and the controls were £¿uc-157£¿ f1 and f2. spears were trimmed 18 cm long after harvest. the highest cumulative marketable yield was obtained by £¿jersey supreme£¿ (43 mg ha-1 in five years), and the lowest one by £¿apollo£¿ (17.8 mg ha-1). marketable yield of both control £¿uc-157£¿ f1 (24.9 mg ha-1) and f2 (24.3 mg ha-1) was similar (p ¡Ü 0.05) to the other jersey cultivars, but higher than £¿apollo£¿. the main disadvantage of £¿jersey supreme£¿ is the purple coloration of its bud scales, and a purple cast to the butt of the spear, therefore discarded for the fresh market, but suitable for freezing. another disadvantage is that spears tend to open to a smaller height than £¿uc-157£¿, and 10% more of its production is destined to internal market (pa¨ªs category)
