Recommendations on planting:

This is a red-jacket table potato sort with a mainly solid texture.
This seed potato sort raises medium to high demands to the ground and moisture. It is highly recommended to plant it into well-cultivated grounds. In case of early harvesting or planting the potato under a tent greensprouting is recommended.

Special instructions:

The Red Sonia sort forms a medium number of tubers in a hole so the seed potato shall be planted with the 30-32cm distance between the tubers and the 75cm distance between the rows (~43.000 plants/hectare). It is recommended to treat the potato against the rhizoctonia disease.
This sort is responsive to systematic fertilization. The Red Sonia sort is referred to the new type of potato with decreased needs in nitrogen. The general (gross) nitrogen value: up to 160kg/hectare (considering the Nmin, organic fertilizers ± correction depending on the peculiarities of the particular region). Together with the К2О (200–250 kg/hectare, C class) and P2O5 (100 kg/hectare, C class) it is necessary to consider the availability of magnesium in the potato. It is also necessary to consider the afterharvesting residues and organic fertilizers.
Systematic blight-protecting treatment is recommended.

Multi-step desiccation shall be conducted in order to maintain the internal and external quality of the seed potato and improve the durability of the jacket. The tuber jacket becomes solid within 3 weeks after the desiccation was conducted.
