Uses: Hay,
pasture, and silage.
Weight per bushel: 60lbs.
Seeds per pound: 220,000
Germinating time: 7 days
Fertilizer: At seeding, Zero N, 110-140lbs. P205, 110-140lbs. K20 at
medium soil test levels. Use borate fertilizers (2-4lbs. B) annually. For
top-dressing 70-90lbs. P205 and 220-360 K20 annually for medium soil test
levels. Split applications: half in fall and half in spring. Lower levels
required for pasture.
pH Range: 6.8-7.0
Soil Adaptation: Deep, well drained soils, with sandy clay loam to
clay subsoils.
Inoculation: Essential. Use commercial inoculants. Cross inoculates
with sweet and bur clover.
Planting: 30-60 days before first killing frost in fall or 30 days
before last killing frost in spring at 15-25lbs. alone, or 10-20lbs. with
3-5lbs. of orchardgrass.
Method of planting: 6" - 8" rows or solid seeded. Conventional
seeding, cover no deeper than 1/4" - 1/2", preferably with cultipacker. A
firm and compact seedbed is essential. No- till seeding (graze or mow to
have sod short). Kill all vegetativ e competition with herbicide, use
insecticide, plant 1/2" - 3/4" deep with no-till drill.
Harvesting: Harvest at late bud to 1/4 bloom, except first cutting.
First cutting should be made in (hay or silage) bud stage or when
orchardgrass begins to head. Alfalfa may be cut 3-5 times per year at 30-40
day intervals, depending upon location in state and average rainfall. Make
last cutting 3-4 weeks before average date of first killing frost in fall or
in time to allow 6" - 8" of re-growth. Allow at least one harvest to reach
1/10 bloom to help persistence.
Harvesting (pasture): Use grazing-tolerant varieties under continous
stocking. Hay-type varieties should be rotationally stocked with 1-7 day
grazing periods and 25-40 day rest periods. Avoid bloat by seeding with
grass, turning cattle into new paddock only after forage is dry (no dew),
and not allowing cattle to get to hungry prior to turn in.
Approximate Yield: 3-6 tons of hay per acre. |

Cimarron SR
Cimarron SR was selected directly from the popular Cimarron line of alfalfa
varieties for greater resistance to sclerotinia crown rot. The Cimarron line
has been developed through many years of field selection under conditions
favorable to sclerotinia outbreaks. As a result, all of the older Cimarron
varieties had a moderate level of resistance to this disease and provided
good protection.
However, using new methods of selection, it has become possible to
incorporate a higher level of sclerotinia resistance into this variety.
There have been improvements in yield and disease resistance in Cimarron SR
as well. It possesses the superior forage quality and stand persistence that
Cimarron alfalfas have become known for
Extra Leafiness: Simarron SR has large leaves and axillary branching along
the stem.

- Extra Leafiness: Simarron SR has
large leaves and axillary branching along the stem.
- High Phytophtora Resistance:
Cimarron SR has high resistance to phytophthora root rot and moderate
resistance to aphanomyces root rot.
- Alfalfa Weevil Tolerance: Cimarron
SR's tolerance tothe alfalfa weevil can reduce the amount of insecticides
needed by half.
- Frost Resistance and Winter Hardiness:
Cimarron SR will remain green and hold its leaves longer in the fall. It
can be harvested or grazed after frost without loss of winter hardiness.
- Sclerotinia Crown Rot Resistance / Late
Summer Seeding: With the improved resistance of Cimarron SR, alfalfa can
be planted in late summer and early fall without fear of stand loss.

HayGrazer's
(top hay producer)
HayGrazer gives hay yields equal to the best hay varieties. Manage HayGrazer
for hay as you would any hay variety. For highest yieldl and quality take
the spring cutting in the bud state. Thereafter, cut every 28-42 days.
Cutting for hay and grazing may be combined in a flexible system for
greater profitability.
