In the modern agro-industrial complex of the Omsk Region Agrokultura LLC places particular emphasis on optimizing cultivation techniques. This improves product quality and ensures stable harvest volumes regardless of seasonal climatic conditions. Cultivation efficiency still largely depends on correctly determining optimal sowing and harvesting times. The leaf lettuce variety Danstar F1 was selected as the study object. The study revealed that Danstar F1 developed and grew steadily throughout the growing season, regardless of sowing time. All varieties emerged within 24 hours after sowing, with the first and third true leaves emerging sequentially and rapidly: the first leaf emerged within 2-3 days, and the third leaf emerged within 6-7 days. The total growing season remains constant at 45 days. Plant height increases gradually, reaching its maximum by the 45th day, ranging from 16.4 cm in winter to 18.1 cm in summer. The maximum yield was recorded in the summer, reaching 10.7 kg/m², while the minimum yield was in winter, at 9.8 kg/m². In the spring and fall, yields are similar, reaching 10.3 kg/m² in spring and 10.1 kg/m² in fall, respectively. The influence of growing season on yield is 13%. The use of modern lighting and microclimate technologies allows for the effective cultivation of this crop year-round, regardless of sowing time.
