Variety traits

Potato yield

Solanum tuberosum L.

Potato yield is a key economically valuable trait measured in tonnes or centners per hectare based on the commercial fraction of tubers.

In the reference 733 varieties crop Potato, where this is mentioned in the description.

In potato variety testing, tubers weighing over 40 g or having a diameter exceeding 40 mm are considered commercial. Yield is recorded on test plots in multiple replicates, with the total weight and fractional composition being documented, after which the performance of the tested variety is compared with the standard for the specific soil and climatic zone.

The average yield in temperate latitudes is 250–300 c/ha; however, the figures vary significantly depending on the maturity group and external conditions. Early-maturing varieties typically yield less than late-maturing ones in terms of total harvest, as the latter have a longer period for tuber biomass accumulation.

The realization of genetic yield potential depends on the quality of seed material, adherence to agronomic practices, nutrient availability, and water management. Potatoes are most demanding of moisture during the tuberization phase, when high temperatures can halt growth and significantly reduce productivity.
