Old World Bluestem Seedings in Western Oklahoma
Scott D. McCoy, Jeffrey C. Mosley, and David M. Engie
OldWorldbluestems (Bothriochloaspp.)are an assemblageof warm-season perennial bunchgrasses first introduced into the United States in 1917 from Europe and
Asia. These grasses are commonly seeded throughout
muchofthesouthern Great Plains forstabilizingmarginal
croplandand for increasingforageproductionon deteriorated rangelands. Old World bluestem seedings can
produce four times the forage of well-managed native
rangeland (Coyne and Bradford 1985). Consequently,
OldWorldbluestems arean ideal choicefor seeded pastures used to complement native rangeland in an integrated forage-livestockproduction system (Sims and
Dewald 1982).
Forthepast30 years, researchers at the USDA's Southern Plains Range Research Station (SPRRS) at Woodward, Oklahoma have been studying these grasses and
developingcultivarssuited to thesouthernGreat Plains
To date, the five mostcommonlyseeded Old World bluestemcultivars are Caucasian, Plains, Ganada, WW-Spar,
and WW-lronMaster. Two experimental cultivars not yet
available commercially, WW-51 7and WW-857,also appear
usefulforthefuture (DahI etal. 1988,Mastersand Britton
1988).
Caucasian bluestem (Bothriochloa caucasica) wasintroducedinto the United States from the SovietUnion (Dalrymple et al. 1984) and was one of the first Old World
bluestems to be introducedinto the UnitedStates. Plains
bluestem (Bothriochloaischaemum var. ischaemum) was
developedattheSPRRS and released in 1982 (Taliaferro
and Harlan 1973). It is a blend of 30 morphologically
similar Old World bluestem accessions collected from
Afghanistan, India, Iraq, Pakistan, Turkey,and the Soviet
Union (Dalrymple1978). Oneofthese30 original accessions was isolatedand released by the SPRRS as WWSpar (Bothriochloaischaemum var. ischaemum) in 1982

(Dewald et al. 1985). WW-Spar is noted for producing
vigorous seedlings. Ganada bluestem (Bothriochloaischaemum var. ischaemum) originatedin Turkey and was
introduced into the Great Plains in 1979 (Dewald et al.
1985). Ganada is noted for its cold tolerance.WW-lron
Master(Bothriochloaischaemum var. ischaemum), aCuItivar tolerant of iron-deficientsoils, was released by the
SPRRS in 1987 (Dewald et al. 1988).

The development and release of these well-adapted
cultivarsenabled many farmers and ranchers acrossthe
southernGreat Plains to establish Old World bluestem
seedings. USDA's Conservation Reserve Program (CRP)
also helped proliferate Old World bluestem seedings
throughout the region. But given the uncertainfuture of

About one-thirdoftheseeded acreage (34%)was baled
for hay in 1989. Twenty-seven percent of the hayed
acreage yielded two cuttings, and none of the hayed
acreage producedmorethan two cuttings.Average harvest dates were July 1 and August 26 for the first and

revealed that singlecuttingscanyield from5,000to8,000

would be expected to increase in most other years. One
respondent stated that the annual production from his
irrigatedfield is consistentlydouble thehay production
from his dryland seeding.
CattleGrazingStrategies
Most respondents (94%) grazed their seedings with
livestock. Beefcattle werethe onlykind of livestock used
and included both cows and stockers. A short duration
grazing (SDG) programwasusedby 13of the29 graziers.
This is a surprisingly large proportion of respondents
giventhe large managerial inputsrequired by SDG. Nonetheless, many ranchers apparently realize that the high
utilization grazing form of SDG (Booysen and Tainton
1978) is well-suited to management of Old World bluestems and similar improved forage species (Dahi and
Cotter 1984).
Sixty-three percentof the respondents used their Old
World bluestem seedings as complementary forage to
allow grazing deferment of their native rangeland pastures. We believe that this is one of the greatest values of
Old World bluestems.
Twoof the most commongrazing management problemscited by therancherswere that (1) foragepalatabilitywassometimes poor,and (2) that foragenutrientquality was sometimes less than livestock required. These
problemshavealso been documentedby research (Dabo
43
et al. 1987, 1988) and emphasize the need for intensive
grazing management of these grasses. Large pastures
grazed at low stock densities for long grazing periods
cannot maintain Old World bluestems in a palatable and
nutritious form.
Summary andRecommendations
Old World bluestems are valuableintroduced grasses
in the southern Great Plains. These grasses enable
ranchers to increase livestockcarrying capacity, provide
grazing defermentfornativerangelands, and provide forage reserves for drought periods. For best results, Old
World bluestems should be managed intensively. Fertilization and periodic burning or mowing will help keep
seeded stands vigorousand productive.Production can
be improveddramaticallywhereirrigation isfeasibleand
economical. Old World bluestems can be harvested for
hay, but palatabilityand nutritive contentdeclinerapidly
with advancing plant maturity. Properly managed rotational grazing programs designed with small pastures
and high stock densitieswill provideexcellent livestock
gains per acre.
When asked whether Old World bluestems had met
their expectations, 30 of the31 ranchers repliedfavorably. It appears that OldWorld bluestems are truly a useful
tool for ranchersin western Oklahoma. Of course, any
tool is onlyas good as the craftsmanusing it. Our survey
demonstrates clearlythat ranchersin western Oklahoma
are indeed managing Old World bluestem seedings in
very successful ways.

The total impact of a dollar produced or spent in a
communityis often measured through the useof a 'multiplier." Multipliers are commonlyused in economicstudies which attempt to show how importantone business

Thereare also twotypes of effects, direct and indirect.
A direct effect is equivalent to the initial impact of the
original production or expenditure. For example, the
direct effect of $1.00 spenton somegood or service in a
community is 1. Indirect effects measure the additional
effects the original purchasemay have as that expenditure"turns-over"within the regionorcommunity. Indirect
effects may range from 0 to 2 or higher.

This example assumes 40% of the money spent in a community
remains in the region while 60% leaks out.
Thus, a dollar spent in the community turns—over 6 times while
