ИНСТРУКЦИЯ ПО ВЫРАЩИВАНИЮ (СТОЛОВЫЙ КАРТОФЕЛЬ)

General

SH C 909 is the same crossing as the SH C 913 (OMEGA x VR808), variety with excellent quality for crisping. Potatoes are uniform in size and shape, average tubers per plant, 15-17. SH C 909 can be stored for a long time, stable and low in the sugars. The SH C 909 is not producing berries like the VR 808.

Seed sizes: 30/40, 40/50 en 50/60.

 

Tuber characteristics

Round to round oval tubers. Uniform in size and shape. The potatoes do have a rough light yellow skin with yellow flesh.  Dry matter content  23 – 24 %. Highly resistant to Globodera Rostochiensis Ro1, resistant to Wartdisease fysio 1.

 

Maturity

Mid late to late crop (5).

 

Field selection

De SH C 909 can be grown on all different kind of soils. The variety is strong against internal defects. Less sensitive to common Scab (6,5).

 

Fertilizing

Relative low Nitrogen application, 15% less compared with the VR 808,  160-200 kg/ha include soil reserve. Application 2/3 at planting and  1/3 after the tuber setting. Phosphate 80-120 kg/ha. The SH C 909 is sensitive for bruising, recommended Potassium per ha: 300-320 kg/ha. It is always good to take a soil test and to see the comments of this test regarding tot he potato crop.

Micro elements

SH C 909 reacts positive to an application with flowable formulations containing Magnesium and Manganese. This can be add tot he Blight program.

 

 

Seed treatment

SH C 909 has a good dormancy (8). Seed can be stored in a mechanical cold store, temperature not below 4 ⁰C, otherwise the crop will start slowly. Recommended to take out the tubers out of the cold store several weeks before planting, acclimation of the tubers. Already in February you can take the seed from the cold store and put it in a place with a temperature of  6 to 7 ⁰C, in combination by box turning system. All the potato eyes will be activated, more stems per plant.  At planting a treatment against Rhizoctonia is recommended.

Agronomy

SH C 909 has a good dormancy, that’s the reason that the start is also slowly. The planting depth like normal. After emergence the crop will develop rather fast with a good ground cover. SH C 909 is stronger against Late Blight compared with the VR 808 but protection against this disease is recommended. SH C 909 is not producing berries.

 

Weed control

Sensitive to metribuzin (Sencor), special the after emergence application can damage the young crop. Even a pre emergence application can give a negative reaction tot he crop in combination with a lot of rainfall. All other chemicals for weed control in potatoes can be used.

 

Crop killing and storage

Crop killing is not really a problem for this variety.  The SH C 909 is a mid late to late variety, so a second application can be necessary. This variety can be stored for a long term, good dormancy and stable and low in sugars.

 

Attention points

     !      Good, deep dormancy (8), acclimate and activate the tubers before planting

     !      No application with Metribuzin (Sencor) in a post emergence application.
