Abstract
The effect on asparagus yield and quality of three planting depth (10, 20 and 30 cm) and two plant densities (22000 and 33000 plants ha -1 ) was assessed in a volcanic soil in the subhumid Mediterranean climatic zone. The cultivar used was UC-157 F1, and the experimental design was randomized complete block in a factorial arrangement, with four replications. Plots were harvested daily during four seasons (1997-2000), and number, weight and diameter of spears were determined after trimming to 18 cm. Marketable yield was determined as the total yield minus culls, and exportable yield as the marketable 7-17 mm diameter spears. No interaction between plant density and planting depth, and no effect of plant density were detected on cumulative marketable yield and percentage of 7-17 mm diameter spears. The marketable yield declined when crowns were planted at 30 cm, although the individual weight of spears increased. This was explained by a decrease in the number of spears per m 2 . The highest proportion of exportable yield (7-17 mm) was
