Variety traits
Asparagus officinalis L.
Asparagus yield is a long-term economic indicator dependent on accumulated rhizome productivity, which varies from 4 to 15 t/ha depending on plant sex, planting density, and cultivation technology.
In the reference 36 varieties crop Asparagus, where this is mentioned in the description.
Commercial harvest of asparagus spears begins in the 3rd–4th year after transplanting, with the maximum plantation productivity occurring between the 4th and 12th years. For breeding purposes, potential productivity is assessed by spear weight, spear height, and the number of spears per plant.
Productivity metrics vary significantly depending on plant sex: male specimens yield 25–50% more than female ones, which has become the basis for developing “all-male” hybrids. Under intensive cultivation technologies, yields reach 9–15 t/ha, whereas at the plot level, about 4–5 kg/m² is considered the norm.
Gross yield is determined by agrotechnical factors, including planting density and the use of covering or soil heating technologies. The crop shows a high response to nitrogen fertilization and the maintenance of an optimal water regime, which ensure the realization of the root system's potential.
