How to achieve high yields per hectareHarvesting by combine
Farmers involved in the cultivation of this crop, tend to collect as much as possible a crop.
Productivity depends on many factors:
- cereal variety, planting target (grain, silage);

- possibility of watering at least 2 times (some varieties - 3-4 watering).
Under favorable agrotechnical conditions, the most popular varieties in Russia yield high yields:
- Lakomka variety - up to 50 c per hectare;
- Spirit variety - 70ts per hectare.
