Abstract
This study was conducted to determine the effects of mild to severe cutting pressures on growth and recovery of spring- and summer-harvested asparagus.
Twenty-four month-old asparagus plants, grown in 27 1 pots, were harvested in spring (March) or summer (July) using harvest pressures of either 3, 6, 9, or 12 spears/plant.
Spear emergence after harvest treatments were completed, did not differ among any cutting pressures; however, more spears of greater longevity were produced after spring harvest rather than summer harvest.
Spear diameter, fern and crown weights at the experiment’s termination, and crown quality were unaffected by cutting pressure or harvest time.
Recovery from harvest pressures in the spring following harvest treatments was similar between spring- and summer-harvested plants and was not affected by cutting pressures.
