GONZALEZ A, María Inés. Evaluation of Green Asparagus Varietis in the Bio-Bio Region, Chile. Agric. Téc. [online]. 2007, vol.67, n.3, pp.227-235. ISSN 0365-2807. http://dx.doi.org/10.4067/S0365-28072007000300001.
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)
