Safflower
Thistle like plant with
spines
Middle East Origin
(desert species)
Sunflower family
One of the oldest crops
Historically for dye & oil
“Best location to grow safflower is
where it doesn’t rain after flowering and
humidity is low”
![Page 3: New Safflower Production in the Southern High Plains, 2010agrilife.org/lubbock/files/2014/03/Safflower-Southern... · 2016. 12. 21. · Safflower Production in the Southern High Plains,](https://reader034.fdocuments.net/reader034/viewer/2022051809/6010ecee91b7fe76ac2f7e36/html5/thumbnails/3.jpg)
Safflower (cont)
20 – 45% oil
Linoleic and oleic acid
Drought tolerant
Strong root system
Down to 10’
High demand for food,
industry and fuel uses
Foliar and head rot diseases
“Rain or irrigationafter flowering can lead to head rot”

Spring SafflowerBest time to plant?
Seeds can germinate in cold temp
down to 40°F
Initial High Plains seeding is best
in March??
Strong root system down to 10’
deep
Heat tolerance ??
Late planting (summer) and
maturity in cool fall is a concern
“Most current varieties are spring types”
![Page 7: New Safflower Production in the Southern High Plains, 2010agrilife.org/lubbock/files/2014/03/Safflower-Southern... · 2016. 12. 21. · Safflower Production in the Southern High Plains,](https://reader034.fdocuments.net/reader034/viewer/2022051809/6010ecee91b7fe76ac2f7e36/html5/thumbnails/7.jpg)
“Safflower likes deep, clayey soil with higher water holding capacity. Light and shallow soils need more frequent
watering or rainfall”
![Page 8: New Safflower Production in the Southern High Plains, 2010agrilife.org/lubbock/files/2014/03/Safflower-Southern... · 2016. 12. 21. · Safflower Production in the Southern High Plains,](https://reader034.fdocuments.net/reader034/viewer/2022051809/6010ecee91b7fe76ac2f7e36/html5/thumbnails/8.jpg)
Safflower Planting
(Clovis 2009)
Plant 1.0-1.5” deep
Seeding rate 15 to 20
lbs./ac
Generally 6 to 10 inch
row spacing
Can use a planter,
but yield potential is
not met
![Page 9: New Safflower Production in the Southern High Plains, 2010agrilife.org/lubbock/files/2014/03/Safflower-Southern... · 2016. 12. 21. · Safflower Production in the Southern High Plains,](https://reader034.fdocuments.net/reader034/viewer/2022051809/6010ecee91b7fe76ac2f7e36/html5/thumbnails/9.jpg)
Fertility requirement
(NDSU)
5 lbs. N per 100 lbs. yield
Depending on soil type
may need P & K
Weed Management
Poor competitor
A few herbicides are
labeled

Relatively few insect
pests
Heavy rain or humidity
causes a number of
diseases
Botrytis head rot is
predominant one

Store at 8% moisture

Harvesting
May planted spring safflower in 2007 yielded
1,245 lbs./ac at Tucumcari and 1,500 lbs./ac at
Clovis with very limited irrigation
Early guesses of yield potential
Rainfed ≈1,000 to 1,200 lbs./ac
Limited irrigation ~2,000 lbs./ac
Winter types are expected to be higher
yielding (but lower oil content)
