Cultivation
Sowing date is an agrotechnical parameter that determines the realization of a variety's genetic potential depending on its biological characteristics, heat requirements, and day length requirements.
Mentioned in descriptions 2 891 varieties reference book.
Sowing date is an agrotechnical guideline tied to the biological characteristics of a specific variety, such as heat requirements, response to photoperiodism, and the rate of development phases. The manifestation of variety characteristics depends on its ability to adapt to changes in calendar dates, with different varieties demonstrating varying degrees of plasticity in realizing yield and product quality.
The evaluation of a variety based on this parameter is based on the distinction between intensive and adaptive types. Intensive varieties require strict adherence to sowing dates to unlock their potential, whereas plastic forms are capable of forming stable yields within a wide time window, mitigating the impact of weather shifts, though often with a lower maximum productivity indicator.
A variety's resistance and response to the sowing date are determined by its sensitivity to light and temperature regimes. For winter crops, choosing the correct date is critical for reaching the optimal development phase before winter dormancy, while for spring crops, their photoperiodic sensitivity is considered, which influences grain quality indicators and maturity dates.
Selection based on the description text, not official resistance ratings: such data is not available in registers. Mention indicates that the trait is discussed in the variety's sources; see the variety's profile for details on what is specifically stated.
