Rapeseed variety Dema is a high-yielding agricultural crop designed for cultivation under various climatic conditions. This crop is widely used as a source of oil, biodiesel, and animal feed, and also serves as an effective cover crop. For successful cultivation of rapeseed variety Dema, proper agronomic practices must be followed, including selection of optimal sowing dates, crop maintenance, and timely harvest. Rapeseed prefers moist soil with neutral pH, good drainage, and temperatures not lower than 2°C, ensuring its resilience and high productivity. A key feature of the Dema variety is its high resistance to stress conditions and diseases, making it a reliable choice for farmers. The plant demonstrates high winter hardiness, rapid vegetation recovery, and medium flowering period. Due to its maximum efficiency in nitrogen utilization and adaptability to short rotation systems, Dema ensures stable and high-quality yields. Another important advantage is its high resistance to fungal diseases and lodging, reducing risks of losses under adverse weather conditions. Performance and quality of the Dema variety are assessed on demonstration fields of VNIIS, where farmers can become familiar with real cultivation results, receive expert consultations, and organize meetings with company managers. This approach allows optimization of cultivation technology, control of weeds, pests, and diseases, as well as timely application of fertilizers and irrigation. Compliance with all agronomic recommendations contributes to obtaining high yields and maximum profitability when growing rapeseed variety Dema.
