Abstract A field experiment was conducted to study the
effects of soil type (sandy loam and silt loam) and soil depth (5, 10, 15,
20 cm) over the crown during harvest on the yield and quality of asparagus
(
Asparagus officinalis L.) spears. It was found that covering the crowns
with sandy loam produced significantly higher spear yield, spear number, and
better spearhead quality than covering with a heavier soil (silt loam). The
increase in spear yield was because of an increase in spear numbers. Spear-head
quality decreased with soil depth.
