Popis:	Asparagus (Asparagus officinalis L.) is typically harvested for up to 6 weeks in spring, but cultural techniques can be used to extend the harvest. To force spear production beyond the normal harvest season, asparagus plants are allowed to grow undisturbed in spring and then are mowed later in the season, resulting in a flush of harvestable spears. Repetitive off-season forcing of asparagus does not appear to be a viable production practice in the temperate climate conditions of the Midwestern United States because the growing season is not long enough to permit adequate replenishment of energy reserves after even a brief forced harvest. An experiment was conducted in southwest Missouri to determine whether a system of rotating late-spring forced asparagus harvests with typical spring harvests would allow plants to recover sufficient vigor to establish a sustainable extended asparagus harvest regimen in the region. ‘Jersey Knight’ asparagus was planted in 1999 and harvested in eight different 3-year rotat...
