INTRODUCTION

EVALUATION OF FORAGE CROP VARIETIES IN NORTH CAROLINA

New forage vari et i es and hybrids are constantly being released from

public and private sources.

In

addtt

ion, forage breeders are continually

interested in testing experimentals under a variety of growing conditions.

In order to determine adaptability and productivity, it is necessary that

these forages be tested under North Carolina growing conditions.

The

f t his pub 1 i cat ion i s top re sent comp ar at i ve dat a on for ages

tested in North Carolina in

1982.

The varieties tested are classed into three major groups: winter

annuals (such as rye, wheat, oats, barley and ryegrass);

s~

an nua 1s for s i 1ag e (s uc h as forage sorghum, sorghum-sudangrass hybrids,

pearlmi llet and sudangrass); and perenni a1 forages (such as alfalfa,

1adino clover, red clover, orchardgrass, tall fescue, bermudagrass and

Pennisetum sp.).

All varieties (except those in the silage tests) were

managed on a multiple-cut system with most varieties being clipped three or

more times to simulate rotational grazing or haying conditions.

Dry forage yields are reported for all entries tested.

Additional

data reported for the silage tests include adjusted silage yield (35% dry

we i g ht ), bi r d damage, hei ght, days to flower, stems per acre, and percent

seed head.

Weather-measuri ng instruments are often not avai 1able at the exact

test sites.

Consequently, climatological data are presented from stations

near est a gi ve n t est and are 1i s ted i nth e appendi x•

I n most cas es

reportiQg stations are relatively close to the tests.

Experimental

lines are sponsored through the USDA-ARS, state

agri-cultural experiment stations and privately owned companies.

These lines

are not available for farm use.

All entries from privately owned companies

(experimental lines or commercial varieties) are tested on a fee basis. The

Crop Science Department, N. C. State University reserves the right to enter

proven varieties to be used as standards, or other varieties of interest.

All vari et i es are from certified sources or from sources which would be

able to verify origin.

This gives assurance as to the purity of the

entries tested and that results reported here could be reproduced.

information of a given test are listed in the table which gives

dry matter yields by harvest for that test.

Winter Annuals and Perennials

The experimental design used for all tests was a randomized complete

block with the exception of FVT 197 (which was a split plot) with four or

fi ve rep

1

i cations.

Plot dimensions were

20

feet long and

2 1/2

feet wide,

with the exception of 5 x

20

foot plots for ladino clover, bermudagrass and

the Penn i setum sp., and 9 x

20

for sorghums.

Blocks were separated by at

least

2 1/2 feet and all

tests bordered by material either identical or

comparab

1

e to that inc

1

uded in

the test.

An exception occurred when

species with major differences in seasonal productivity were evaluated.

In

these cases borders were maintained between species.

All

a v e r,

be r mud a g r ass and the Penni seturn

s p , contained three rows nine inches apart.

Seeding was accomplished with

a push-type Planet Jr. seeder or a specially designed cone planter which

was calibrated for each entry.

Ladino clover was broadcast seeded by hand;

bermudagrass and the Penni setum sp , were established by placing sprigs

into rows.

Seed ing rates for all tests were adjusted to

100%

germination

based on test conducted just prior to planting.

annuals were seeded in May.

Plots were harvested with a self-propelled, flail-knife chopper.

It

was designed specifically for small plot work with the wheels spaced so the

harvest rows and the stubble were not damaged during harvesting.

Each plot was evaluated for weed percentage.

When estimated to be

greater than 5% of the harvested forage dry matter, weed contribution was

estimated and subtracted from total herbage weights.

Thus dry forage

yields listed in this publication are on a weed-free basis.

When subsampling, the percent dry matter values from two

was determined to be from 5 to 9%.

Extreme variations did not exist within

separate harvests and no attempt was made to standardize dry weight yields

The primary goal was to evaluate forage

Experimental Procedure for Silage Tests

The summer annuals were tested at two locations (1) University Farms

in

Raleigh (FVT 199) and (2) Washington County (FVT 198).

The varieties

were pl anted in a randomized complete block design with five replications.

Each vari ety was pl anted in

three rows 36 inches apart and 20 feet in

length.

Repl ications were separated by 6 foot borders which contained a

single row of FS-1a as a border row.

Each variety was planted with a

speci al ized small plot, cone planter which was calibrated for the entry.

Seeding rates were between 80,000-100,000 seeds per acre with the exception

of cor n (28, 00 0 ) •
