OUTSTANDING QUALITIES
- Mid-maturing, short day red onion hybrid
- Uniform, firm, globe shaped bulbs
- Attractive shiny, deep red to purple bulb skin colour
- Excellent internal flesh colour
- Excellent root disease resistance against soil borne pathogens
SV7030NS is a mid-maturing, short day, red onion variety. SV7030NS produces firm, uniform, globe shaped bulbs with neat, thin necks. SV7030NS’s bulbs have two tough outers scale leaves each with an attractive shiny, deep red to purple colour. SV7030NS is a vigorous grower with a high yield potential and good bolting tolerance. In addition, SV7030NS has high resistance to the soil borne fungal pathogen, pink root (Phoma terrestris syn. Pyrenochaeta terrestris) and intermediate resistance to Fusarium basal plate rot (Fusarium oxysporum f. sp. cepae). SV7030NS is suitable for direct seeding as well as seedling transplants.
SPECIAL VARIETAL REQUIREMENTS
- SV7030NS has a vigorous root system – nitrogen based fertilisers late in the growing season should be strictly managed
- Red onions need to be cured properly in order to develop the distinctive red internal colour – all red onion varieties have a white flesh colour when recently harvested or when used as fresh green (not cured) onions

|
GROWING AREA |
Grown between 23 – 35° latitude. Refer to the sowing guide for the recommended sowing period in different production areas. |
|
AVERAGE SEED COUNT |
220 – 320 seeds per gram or 220 000 – 320 000 seeds per kilogram |
|
SUGGESTED SOWING DENSITY |
Density depends on the size requirement of the bulbs and the target market/uses of the final product, however we suggest: Final population of 750 000 – 950 000 plants per hectare |
|
SEED REQUIREMENT PER HECTARE |
Direct sowing: 900 000 to 1 200 000 seeds per hectare / 3.5 – 4.0 kg seed per hectare Transplant: 5.0 – 5.5 kg seed per hectare |
|
MARKET USES |
Bunched, fresh market, pre-pack and processing |
|
SPECIAL FEATURES, BENEFITS AND REMARKS |
Attractive and tough shiny, deep red to purple tunic. Red onions need to be cured properly in order to develop the distinctive red internal colour – they have a white flesh colour when recently harvested or when used as fresh green (not cured) onions. |
