In this
article we will answer to the question: What is the yield of
sunflower?
In this
calculation, it is assumed that 1 ton of sunflower seeds is 73.487 bushels.
What is
sunflower
seeds bushels means? 1 US
bushel it is seeds that
can
be filled in volume
= 35.239072 litres. Good sunflower varieties have oil content in seeds about
50-55%.
Sunflower yield is
not a fixed, the yield level depends from weather and soil conditions and
the skills of the agronomist!
Different
types of sunflower varieties have different
mass of seeds per unit of volume.
The heavier
oilseed varieties of sunflower, and the lightest are those used for hulling,
such as Turkish white sunflower varieties.
Confectionery sunflower seeds have an average weight. Next we will show the
oil seed sunflower yield estimation.

Typical oilseed sunflower yield is 68.40-74.35 bushels per acre
(or 2.3-2.5 t/ha) - sunflower
oil yield 1026 - 1227 pounds/acre (or 1.15-1.37 t/ha).
In general
cases the oil yield will be less ass will losses for oil extraction.
Depending on the year - in dry conditions without irrigation (in the
South), if it rains only in spring or rarely during the season, sunflower
yields
23.79-59.48 bushels per acre (or 0.8-2.0 t/ha)
- sunflower oil
yield 357 - 981 pounds/acre (or 0.4-1.0 t/ha).

Sunflower plant died during flowering from
drought due
to late sowing
Despite the fact that sunflower is one of
the most drought-tolerant crops,
but risks for sunflower and other crops will increase
with climate change. Please ask
professionals of Agricultural Consulting how to reduce this risks and for
advice of sunflower growing!

In conditions of sufficient or medium moisture - a good farmers gets a
sunflower yield of 89.22-104.09 bushels per acre
(or 3.0-3.5 t/ha) -
sunflower oil yield 1338 - 1717 pounds/acre (or 1.5-1.9 t/ha).
By irrigation, the typical sunflower yield can be
118.96-148.70 bushels per acre (or 4.0-5.0 t/ha)-
sunflower oil yield 1784 - 2454 pounds/acre (or 2.0-2.8 t/ha).
According
to our data from
Agricultural Consulting practice, the
record yield without irrigation on black soils and sufficient rainfall (in
favorable years) is 148.70-169.51 bushels per acre
(or 5.0-5.7 t/ha) -
sunflower oil yield 357 - 981 pounds/acre (or 0.4-1.0 t/ha) - sunflower oil
yield 2231 - 2797 pounds/acre (or 2.5-3.1 t/ha).
A
World Record
of sunflower yield without irrigation -
6.21 t/ha (184.68 bushels per acre)
was obtained in 2016 in the Kabardino-Balkarian Republic by farmer V.
Aramisov (seed moisture during harvesting was 5.8-6.9%, oil content -
52-53%. 61 thousand seeds were sown per hectare, 55-57 thousand
plants/hectare stood for harvesting).

Sunflower plants in
the field are investments of big
money, and in order not to lose this money, you need to ensure that
everything is normal, that everything is done correctly and that the
investment is well. For this, independent professional monitoring and
supervision are needed.

Independent audits and monitoring of sunflower fields allow
to determine the real situation, i.e., you can identify what is in reality -
it is possible to monitor the situation with your investments, business or
pledged property.

In order to
get a high yield of sunflower in your conditions, you should select those
varieties that will give the highest yield in your conditions.
The fact is that in the same field, different varieties of sunflower
will give different yields. And the difference between good and bad
varieties for your conditions can be up to 40-50% of the yield (usually
15-30%).
This is due to genetic differences between different
varieties, as well as the quality of the seeds. Seeds must be of one size
and fraction and have of good germination.
Also, the same variety can
give different yields in different years and with different care. In one
year, one variety may show the highest yield, in another year, another
variety may give the highest yield.
The determining factor for the
choice is the average yield of a particular variety, on average over three
years. New, higher yielding and more profitable sunflower varieties also
regularly appear that need to be tested.
Therefore, several different varieties with different levels of early
maturity should be sown.
