Dessert R78

Dessert R78 is a MDMV resistant super sweet hybrid with medium maturity length. The plant is strong growing and highly adaptive. The variety’s fertility quotient is outstanding: almost all plants grow a standard corn-cob. Its adaptability, viral resistance and high fertility levels ensure that sown almost any time (from mid-April to early July) it yields reliably. Harvestability is flexible: it preserves sweetness even in an overripe condition and can be kept standing for a long time.

Dessert R78 is the tastiest member of our variety line. Its crop is extremely sweet and juicy, the kernels are of medium size. Primarily threshed product is suitable to be produced from this hybrid.

Dessert R78 is a high-yielding, flexibly harvestable hybrid with outstanding taste quality.

GROWING TECHNOLOGY CORNER POINTS

for the large-scale production of Dessert R78

TOPCORN Kft., 2021

ISOLATION (from non-supersweet sweet corn and maize)
Distance: at least 150m or
Time: at least 10-day flowering time difference - timing of sowing, or

- variety pairing (Dessert R78 + Jumbo)

SEEDBED PREPARATION
At the time of sowing the seed bed should be - settled (natural capillarity)

- with an even surface

In case of dry soil conditions irrigate (20-30 mm/m²) 4-8 days before sowing to build water reserves.
Immediately prior to sowing only loosen the soil till sowing depth (3-4 cm).

TIMING OF SOWING

Optimum sowing period: from the beginning of April onward, until early July, when the average soil temperature at sowing depth reaches 12 °C
Wait with sowing, if according to forecasts a cooling is expected in 24-48 hours.

SOWING MACHINE ADJUSTMENT

Seed discs with smaller holes (3-4 mm) are required ('sunflower' settings)
Reduce driving speed

(» better soil tracking » more uniform sowing depth » rapid and uniform emergence »

» consistent crop = bigger yields + less deduction by processors!).

Sowing density: 52-58 thousand germ/ha (10% less than conventional)

SOWING DEPTH

The optimum sowing depth is determined by taking into account the following factors:

in the specific area the sowing machine can ensure a uniform drilling depth
the seed should have contact with a settled wet layer of soil

(or: leavening irrigation / with linear only! / within 24-48 hours!)

the seed should not go deeper than 4 cm

CHEMICAL WEED CONTROL

Base treatment at the beginning of emergence (it’s safe enough then): Gardoprim Plus Gold
Post-emergent treatment: Laudis (till 4-5 leafs it’s safe to use it on corn)
Other post-treatments are considered high-risk (yield and quality reduction).

CARE

The initial rapid and steady development should be helped by all means:

starter fertilization (P-dominant NPK), as base- or possibly foliage fertilizer
regular irrigation started in time and as necessary

(Initially with a lower water dose /10-15 mm/, but more often)

in the root switching period (3-5 leafs) in case of dry weather, irrigation is a must!
use cultivator with shallow settings (after irrigation or rain)

Dessert R72 is a very early maturing (1-2 days after Spirit) super sweet hybrid. Its seeds are usually strong in vigor with a strong initial development even in the case of early sowing. The plant is MDMV resistant, medium in stature, and has excellent root strength.

Despite maturing early, its productivity is outstanding: it is competitive with mid-seasonal varieties! Also suitable for intermittent sowing. It must be isolated from other types of varieties (eg Spirit)!

The threshed product of Dessert R72 is of a quality similar to that of Dessert 73.

Dessert R72 is a high-yielding super-sweet variety; for early, intermittent sowing
