Winter rapeseed variety Moroz is characterized by high cold resistance, which is a key factor for successful cultivation of this crop under harsh winter conditions. Rapeseed can withstand frost down to -15°C, and according to some data, even down to -18°C without snow cover, but lower temperatures may cause damage and freezing of plants. To ensure optimal winter survival, it is important to consider not only natural climatic conditions but also to properly organize agronomic measures, including timely sowing dates and plant treatments.
The quality of winter survival directly depends on the condition of the plants at the end of the autumn growing season. For the Moroz variety, optimal parameters are so-called "three eights": the root neck width should reach 8 mm, the number of leaves should be 8, and the root length should be 8 cm. Achieving these parameters helps increase cold resistance and improves the chances of successfully passing the winter period. To regulate plant development and achieve these indicators, special plant growth regulators are used, which can accelerate or slow down vegetation depending on sowing conditions.
After passing winter cold and April frosts, plants of the Moroz variety require additional protection against cold stress. For recovery and stimulation of growth, it is recommended to use stress-protective agents and fertilizers, such as boron fertilizers. It is also important to prevent fungal diseases using fungicides, which helps maintain plant health and increases yield. Growth regulators help maintain high vegetative rates, which, combined with proper care, ensures maximum potential yield of winter rapeseed variety Moroz.
