Tobacco Krupnolistny 24 Seeds

Krupnolistny 24 is a Nicotiana tabacum variety offered here as seed for growing the plant. The product card describes a medium-maturing, large-leaf variety with wide oval leaves on a conical plant that reaches 1.6 to 1.8 m (5.2 to 5.9 feet). It lists the parentage as a cross of Debreceni 40, Sobolchski 193 and Triumph, and says the variety was originally grown in Zakarpattia. The notes below follow that card; where it gives no figure, this page gives none either.

Also known as: common tobacco, cultivated tobacco, tambaku (Hindi), tabaco (Spanish/Portuguese), tabac (French), Tabak (German), tütün (Turkish)

These are common names of the species Nicotiana tabacum. Krupnolistny 24 is the name of this particular variety, and the store lists it as Tobacco Krupnolistny 24.

Growing Krupnolistny 24 from seed

Nicotiana seed is very fine and needs light to germinate, so it is sown on the surface and never buried. The figures below come from the product card and are approximate guides, not results measured on a specific seed lot.

• Sowing: surface sow and leave the seeds uncovered, because light is needed for germination.
• Temperature: the card gives 20 to 25 C (68 to 77 F) for germination.
• Germination time: 10 to 14 days at those temperatures.
• Spacing: 50 to 60 cm (20 to 24 inches) between plants.
• Light: full sun to partial shade, in a temperate to warm climate with plenty of sunshine.
• Soil: fertile and well drained.
• Water: moderate, keeping soil moisture steady rather than soaking the bed.

A mature plant of this size and spacing needs a roomy bed. With 50 to 60 cm between plants and a height of up to 1.8 m, the wide leaves have space for air and light around the foliage. Keep young seedlings evenly moist, harden them off gradually, and plant them out once nights are reliably warm.

What is not yet recorded

No seed specifications have been saved for this variety yet. For that reason this page does not state a germination percentage, a viability period or a seed size. The card gives no sowing date relative to frost, so none is invented here. Photographs in the gallery have not all been reviewed against this variety, so this text makes no claims about the plants in them beyond what the card says.

FAQ

How do I sow Krupnolistny 24 seeds?

Place them on the surface of moist, well-drained soil and do not cover them, since the seeds need light to germinate. The card suggests a temperature of 20 to 25 C (68 to 77 F).

When should I sow Krupnolistny 24?

The card does not name a sowing month or a number of weeks before frost. It gives 10 to 14 days for germination, so allow about two weeks before judging a tray, and move seedlings outdoors only when the weather is warm and settled.

How tall does Krupnolistny 24 grow?

The card gives 1.6 to 1.8 m (5.2 to 5.9 feet), with 20 to 22 wide oval light green leaves and pink flowers. Treat this as approximate, since light, soil and spacing change the final size.
