Abstract
A field experiment was conducted to study the effects of soil type (sandy l oam 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.) sp ears. It was found that covering the crowns with sandy loam produced signif icantly 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.
