The document is a technological regulation developed by the National Academy of Sciences, providing a detailed framework for cultivating spring rapeseed (canola) for oilseed production. It outlines soil requirements, crop rotation principles, tillage systems, and fertilizer application. Spring rapeseed is best grown on well structured loamy and sandy loam soils with sufficient humus and balanced pH. The text emphasizes the importance of selecting proper predecessors, avoiding disease promoting rotations, and ensuring adequate soil preparation to retain moisture and suppress weeds. Extensive nutrient guidelines are provided, including calculations for fertilizer doses, micronutrient needs, sulfur application, and liming of acidic soils. A large section is dedicated to seed preparation, sowing practices, and crop management. It includes requirements for seed quality, seed treatment with fungicidal and insecticidal preparations, and recommended sowing dates across various regions of the country. The Regulation describes optimal seeding rates depending on variety, soil fertility, and hybrid type, as well as acceptable seed chemical composition for “double zero” quality standards. Comprehensive weed control, pest management, and disease monitoring guidelines are given, with tables describing detection methods, economic thresholds, and approved pesticides. Growth regulators are recommended to improve branching and yield stability. The final part of the document focuses on harvesting, post harvest processing, storage, and seed production standards. It describes both direct and separate (swath) harvesting methods, optimal harvest timing, and the use of desiccants and film forming agents to reduce pod shattering. Detailed procedures for cleaning, drying, sizing, and storing rapeseed are provided, including temperature limits, drying regimes, and required machinery. Strict conditions for maintaining seed viability during storage and ensuring varietal purity in seed production are also included, such as spatial isolation distances, sorting requirements, and certification procedures. Overall, the regulation provides a comprehensive, step by step technological guide to maximize yield, quality, and safety in spring rapeseed cultivation.
