Frost-resistant winter hydrid. He came to Ukraine from Canada, where the frosts are much stronger than ours. Crops withstand even snowless winters without a noticeable decrease in productivity.

Sowing
The optimal harvest "Alaska" gives in forests and forest-steppes. The main condition is to observe the sowing rate of 800,000 to 1 million seeds per hectare. It is possible to use most types of
fertilized, except for the potassium glyphosate salt solution.
Cleaning
It is permissible to harvest the crop by different methods: direct combining or separate. The decision is made depending on how evenly the crop has ripened and whether there are many weeds in the field. The separate method provides several stages of cleaning. First, the so-called "mowing into rolls" is performed: the stem is cut 25 cm above the ground, leaving the lower pods in place. Mowing is done in the morning or in the evening. Next comes threshing. Threshing should also be planned for the morning or evening. The operation is possible at a humidity of 10-12 percent. For this, special devices are used for
harvesters PKK-5. The separate method is optimal for fields with weeds or in the case of uneven ripening of the crop.
