Addition — winter rapeseed, a classic hybrid with a range of important agronomic advantages. It is characterized by an early spring start, ensuring rapid plant development and early flowering and maturation. This feature allows harvesting before winter wheat sowing, minimizing spring moisture loss and reducing risks associated with lodging and uneven maturation. The compact plant architecture promotes efficient use of soil moisture reserves and high thousand-grain weight even under high temperatures and adverse weather conditions. High winter hardiness and low tendency to elongate the growth point in autumn make this hybrid a reliable choice for early and optimal sowing dates. Addition features a balanced plant structure, ensuring synchronized pod and stem maturation, which significantly improves threshing quality and reduces yield losses. Thanks to these characteristics, the hybrid demonstrates high resistance to adverse factors such as lodging and inefficient nitrogen use. This makes it especially attractive for farmers seeking maximum productivity and quality yields at minimal cost. To enhance the efficiency of rapeseed cultivation, Addition is recommended to be treated with growth stimulants containing synthetic analogues of natural growth regulators. These substances help neutralize the effects of abscisic acid and stimulate plant growth and development, which is especially important during the large bud and flowering stages. This allows for further improvement of yield and crop resilience under various climatic conditions.
