Asparagus productivity is defined by a cultivar's ability to produce a stable volume of marketable spears that meet standards for size, diameter, and quality, measured in mass per unit area.

Productivity assessment is based on recording the qualitative and quantitative parameters of spears throughout the harvest season. Marketable yield is evaluated considering spear length and diameter, absence of mechanical damage or curvature, and the degree of head opening. In the professional community, a yield of 9–12 t/ha for white asparagus is considered high, with a marketable yield exceeding 5 kg/m² also regarded as a strong result.
Actual productivity is influenced by the genetic potential of hybrids, where the use of 100% staminate (all-male) forms increases yield by 20–50% due to the lack of resource expenditure on seed production. Other significant factors include the age of the plantation, which requires reaching full production by the 3rd–4th year, planting density, and the condition of the above-ground foliage after the harvest season, which is essential for accumulating carbohydrate reserves for the following season.
