Description

Barbatella Sultanina (10 pcs)

Rootstocks: 1103P - K5BB - S04 - 140RU - 420A (We will send you the graft carrier available at the time)

Very old variety originating in Asia Minor. It is the most widespread seedless variety in the world and is used both for fresh consumption and for sultanas; also known as Thompson Seedless.

  • Ampelographic characteristics: bud with open, green, glabrous apex, green, glabrous, unfolded apical leaflets. Leaves are medium-sized, pentagonal, green, glabrous, with overlapping lobes. Cluster: medium-large, pyramidal, moderately compact. Berry: small, uniform, ovoid, with thin but resistant skin and crunchy flesh.
  • Cultivation and pruning: requires expanded forms of cultivation with a high number of buds. Green pruning, leaf removal and suckering are necessary. An average berry weight of about 6 g can be obtained by annular incision and the use of gibberellic acid.
  • Sensitivity to disease and adversity: sensitive to coulure, especially in temperate climates and fertile soils. Evidence of disaffinity to 140Ru and SO4.
  • Overall assessment: interesting variety for its seedlessness and response to gibberellic acid treatments and annular incision. Excellent resistance to transport, appearance and organoleptic characteristics.

Phenological and agronomic characteristics:

  • Sprouting time: medium.
  • Ripening time: medium-late.
  • Vigour: very high.
  • Real fertility: 0.8.
  • Production: high.
  • Bunch weight: 400 g.
  • Berry weight: 3 g.
  • Seeds: absent.
  • Sugar content: 16%.
  • Total acidity: 3.2‰.
  • PH: 3.65.
  • Resistance to transport: medium.

Clones in multiplication: Sultanina VCR122: selected in Crete, it presents above average vigour and productivity; the bunch is more than medium, pyramidal, with medium wings, slightly semi-sparse; the berry is medium, uniform, with a consistent yellow skin. The detachment and crushing indexes are good to excellent; the sugar level is good and the total acidity is contained. The larger size of the berry and the excellent detachment index make the clone particularly suitable for production for fresh consumption.

Other clones in multiplication: Inra-Entav 919

RULES TO PLANT A VINEYARD

1. PLOW

You must perform this operation always with dry soil
A) On arable land is generally sufficient to ripper + to plow
B) On planting soil is generally sufficient to plow with an escavator and to clean the old roots.
If the previous crop was a vineyard, it is a good idea to leave the soil fallow for at least three years (after plowing). This procedure represents a valid possibility of defence against soil nematodes.

2. SOIL FERTILIZATION
Use organics and if it is a reimplantation, use Calciumocyanamide.
This fertiliser has a protective effect on the soil and the crop, especially against fungi.

3.PROPAGATING GRAPE VINE CUTTINGS
The planting should be carried out in temperate soil. The grafting point should be 8-10 cm above ground. Avoid shaving the redices. As much as possible, put sand and/or peat in contact with the roots (the root fears asphyxiation, while it needs a micro-oxygenation). Never fertilize in a localized manner (near the roots). Never water the rooted cuttings before summer.

4.SPRING WORKS
When sprouting, the root apparatus must be heated as soon as possible. Work the soil repeatedly every 7/10 days at increasing depth (up to 20 cm), taking into account the moisture of the soil. When the apex of the bud starts to grow, it means that the root system is functioning. Only then can we stop watering the soil. Failure to grow due to access to water is often confused with a lack of water. This is why watering is used which is expensive, useless or even worse.

5.SPRING CURE
Protect vegetation from Peronospora. To each treatment add nitrogen (N) and iron (Fe) foliar fertilizer. Do not make any radical fertilization.

6.SUMMER CURE
Continue with the defense against Peronospora by suspending the addition of the foliar fertilizer. This defense should be reinforced in late summer and should be continued until vegetation growth stops.
The September/October blight is destructive, to the point of bringing death to the whole plant (if it has not lignified). The rooted vine lacks clusters, so lignification occurs at the end of the vegetative cycle.

7.TECHNICAL VISIT
If incomprehensible anomalies persist after this procedure, contact an agronomist or the VCR Technical Service promptly before carrying out arbitrary procedures which may be unsuitable, expensive and/or worsening.
