This document is intended as a guideline for growers

who have chosen Bronsino and who want to make use

of the experiences of this variety in the several trials over

the past years. However, you should take into account

your own specific circumstances and goals as these can

influence the situation.

Bronsino combines a normal crop length with a fast

truss development. Some remarkable features of this

variety are the shiny red fruit, the strong green parts and

the fast coloring down the truss. In addition, the variety

has proven to maintain high average setting during hot



Bronsino does not require special treatment during the

propagation period. However, it is good to take a few points

into account. The plant type of the young plant is fairly

large with quite a dark colour. Artificial lighting can be used

in propagation but depends on the wishes of the grower

and what time of year planting takes place. After topping,

the first true leaf should be trimmed. Moreover, a strong

rootstock is preferable.

Start of the cultivation

Bronsino normally produces a nice uniform plant. The

advice is not to place the plant on the planting hole until the

first truss is almost in full flower. Fairly soon after planting

implement a day/night difference and be careful during dark

conditions that the average 24 hour temperature is not too

high. This to ensure good setting on the early trusses.

Later in the crop Bronsino can be grown fairly fast with a

flat temperature regime.

However, be alert when the plant does have a higher

plant load and/or in low light conditions to keep the heads

sufficiently strong. Long and deep pre-nights are not

necessary. In fact, they will increase the chance of king

fruits. To have a sufficient elongation/stretching of the truss

it is not recommended to have a morning dip.

Plant type

The active plant length is normal even though it holds 8 to

9 trusses. Bronsino has quite a large leaf and a dark crop

colour. The heads grow close to the string and the variety

should not give a lot of torn trusses. The trusses develop

smoothly and the flowering speed is high. This results

together with a good endurance in a high final production.


Bronsino is a labour friendly variety of average length.

Removing leaves (deleafing) goes smoothly. After the 4th-

5th truss a leaf can be removed from the head. Towards the

summer, depending on the condition of the crop, this can

be continued every second week. The usual stem distance

(density) applies also to Bronsino. Depending on the height

of the glasshouse a final density of 3.3 stems per m² is

usually sufficient. Experience until now shows that keeping

an extra stem goes pretty easily.

Truss clipping

The trusses should be clipped or scraped for as long as

possible (For October 15th sowing: first 8 trusses. For the

November 1st sowing: first 5-7 trusses.). To clip the trusses

is strongly preferred.

Truss pruning

By default, every truss can be pruned to five fruits

throughout the whole season. The variety produces more

than enough flowers, but to keep six fruits is not advised

since the last one will not lie flat, rather it sticks up

somewhat making it difficult to pack


Bronsino does not have any specific nutrient requirements.
