wheat,

and

could

not

be

harvested

protein

for

spring

barley

and

spring

wheat,

respectively.

All

spring

wheat

varieties

tested

formed

seed

at

Hingham,

but

approximately

half

of

the

spring

barley

varieties

formed

few

if

any

heads.

Clark,

Harrington,

and

Kimberly

barleys

were

among

the

most

sensitive

to

this

environment.

Seeding

at

rates

of

15

to

30

seeds/ft=2

did

not

affect

the

production

of

Lew

spring

v^heat

and

the

Clark

cultivar

selected

to

test

spring

barley

rates

survived

poorly.

Variability

was

high

within

these

data

because

of

severe

drought

conditions,

therefore,

these

results

should

be

used

cautiously.

RESULTS!

Off-station

variety

nurseries

and

seeding

rate

experiments

were

seeded

under

no-till

recrop

conditions

in

northern

and

central

Montana.

Winter

wheat,

spring

wheat,

and

spring

barley

trials

were

sown

near

Moccasin,

Conrad,

Havre,

and

Hingham.

Research

efforts

were

hampered

by

severe

drought

or

hail

damage

at

all

locations

and

forced

the

abandonment

of

several

experiments.

Spring

grains

were

harvested

at

the

Daryl

Spicher

farm

southwest

of

Hingham

(Tables

1

to

3).

These

trials

were

sown

as

paired

rows

into

recropped

barley

stubble,

with

four

replicates

for

each

treatment,

using

the

specialty

research

Yielder

Drill

III

partially

-funded

by

the

Montana

Wheat

and

Barley

Committee.

Protein

concentrations

were

around

18

to

207.,

however,

average

grain

yields

were

generally

less

than

5

bu/ac.

Seed

formation

was

reasonably

normal

for

all

spring

wheat

varieties,

but

was

limited

for

several

lines

of

spring

barley.

Production

of

Lew

spring

wheat

was

not

influenced

by

seeding

rates

ranging

from

15

to

30

seeds/ft=®

and

Clark

spring

barley

use

in

this

trial

survived

poorly

at

Hingham.

FUTURE

PLANS=

Continue

studies

and

the

evaluation

of

new

and

recommended

small

grain germplasm

under

conditions

in

the

Central,

areas

of
