Resumen
A trial was established using three month old asparagus (Asparagus officinalis L.) plants in a volcanic soil at Chillán (36°32 S; 71°55 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 ≤ 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 (País category)
