The document is a comprehensive technological regulation for cultivating winter rapeseed, issued by the National Academy of Sciences. It outlines soil requirements, suitable predecessors, and full agronomic practices for achieving high and stable yields. Optimal soils are fertile loamy or sandy loam types with a pH of 5.6–7.0 and sufficient nutrient content. The Regulation specifies that rapeseed should not be grown in monoculture and must return to the same field only after 3–4 years. It provides detailed guidance on soil preparation, emphasizing timely plowing, proper seedbed formation, and avoidance of minimal tillage systems that may reduce yields. The document describes fertilizer application, seed preparation, and sowing standards in depth. Winter rapeseed has high nutrient demands, and recommended fertilizer doses are calculated based on planned yield and soil analysis. Guidance is also given on nitrogen split application, the importance of sulfur and microelements, and foliar feeding. For sowing, the regulation defines optimal dates, seeding density, and depth, as well as requirements for seed quality and pre sowing treatment with fungicides, insecticides, or micronutrients. It also highlights the use of growth regulators in autumn and spring to optimize plant development and improve overwintering. Further sections provide detailed instructions for weed, pest, and disease control, as well as harvesting and post harvest processing. The main pests and diseases are listed with methods for monitoring and thresholds for treatment. Recommendations include approved herbicides, insecticides, fungicides, and conditions for effective spraying. Harvesting guidelines focus on reducing seed loss by using pre harvest treatments, appropriate combine adjustments, and timing based on seed maturity and moisture. Post harvest sections explain cleaning, drying, sorting, and storage requirements, including optimal temperatures and moisture levels that ensure seed viability and prevent deterioration.
