INTRODUCTION To properly evaluate a soybean variety it is necessary that it be grown at a number of locations, at various planting dates, and over a period of years. This will subject the variety to differences in soil and cl imatic conditions that occuri:throughout the State The most common 1 imiti ng factor i n soybean producti on is inadequatemoisture during pod development and filling. Since soybeans are highly photoperiodic, the blooming period, period of pod development and fill, and. maturity date of a particular variety do not vary greatly from year to year. Thus, it ~ds important that varieties from more than one maturity gruop be evaluated at each location. Continued testing and evaluation .of soybean varieties and experimental strains by agricultural experiment stations are essential if farmers, County Extension Agents, seedsmen, and other agricultural workers are to be provided with information to help them select varieties .best adapted to their locality and best suited to meet individual requirements.

EXPERIMENTAL PROCEDURES
Tests in 1979 were conducted at Substations and Experiment Fields of the Alabama Agricultural Experiment Station of Auburn University and two locations on cyst nematode infested fields (Moody Farm, Stevenson, Alabama, and Engel Farm, Summerdale, Alabama) A randomized block design with 4 replications was used at each location with the first planting made at the optimum time for maximum yield. Plots were planted with regular commercial soybean planters equipped with special seed hoppers adapted for small :plots. Plots were four rows wide and 23 feet long with _16 feet of the two inner rows harvested for yield determinations. Harvest was done with a K.E.M. small plot combine at all locations. Row width varied from 36 to 40 inches. depending on location. Seeding rates were 10 viable seed per foot of row based on germination at 750 F. All plot areas were fertilized according to -soil -test. The entries in these tests included varieties- released prior to 1979, a number of unreleased lines in the late.. stages of development from the USDA. Regional Testing -Program, and some commercial lines. Sources of seed are .listed on pages 8, 9, and 10.

.DISCUSSION OF DATA
Since results of field plot research are. influenced by inherent soil differences and soil moisture availability, it is not possible to determine exactly the yield potential of a variety at a given location. Varietal performance may also vary from year to year because of variation in rainfall, temperature, diseases, and nematodes. Therefore, long term yield averages are more reliable in evaluating varietal performance.

Differences in yield for 1979 have been computed using Duncan's Multiple Range Test at the 5% level .of probability. Yields followed .by the same letter are not considered to be significantly different. Coefficients of variation (C.V.) are footnoted in the tables. This value reflects the relative precision of the experiment; a small C.V. indicates more precision. n- estimating the relative performance of

varieties.
SEASONAL CONDITIONS Early season moisture was quite variable during the growing season in 1979. Northern. Alabama. had sufficient moisture early for good stands. and early. growth at .both Belle Mina and Crossville. At Winfield a drought of 25 days during late June and early July delayed growth of first Splanting and. dry soil conditions delayed .the second planting from mid.June to mid-July. Rainfall-of 13.7 and 11.1 inches at Belle Mina and Crossville, respectively, during. the vegetative growth of the early plantings - resulted in excessive growth and lodging of full season and late varieties at these two locations. Some lodging also occurred with the taller varieties at Monroeville, Winfield, and Brewton at the early plantings. The severe lodging that occurred at Fairhope was the result of hurricane Frederic. This was not only a lodging problem but a loss of more than 50 percent of the leaves. Good moisture at all three northern locations during the pod fill periods (Table 1) resulted in average yields of 42, 39, and 30 bu./a.for early planting at Belle Mina, Crossville, and Winfield,- respectively. Rainfall in central Alabama was adequate for good stands at all locations. Uniform vegetative growth was interrupted by an extended dry period .of 20 to 24 days in June at all -locations. It was also dry in August and early September at Marion Junction and Prattville. This resulted in.average yields of 14 and 22bu.a.for Prattville and Marion Junction, respectively, which were the lowest for any test location in 1979. Good rainfall in late August and September (table 1) at Camden resulted in good soybean yields with an average yield of 37 bu./a.for 44 varieties. Rainfall in south Alabama was adequate for good stands for all. locations. However,.. Monroeville was very dry in June with only 2.1 inches over a period 34 days which extended into early July. Headland also had an extended dry period of 25 days in late July and early August which occurred during the late bloom through early pod development stage for full season soybean varieties at this location. Total rainfall for the months June and July of 14.4 inches at Brewton, 11.8 inches at Fairhope, 10.8 inches at Monroeville,

and 12.2 inches at Headland were above normal for these locations and resulted in good plant height at all locations. Despite this, lodging was only a problem with the taller varieties at Brewton and Monroeville for the southern locations. Good rainfall at all southern locations during pod fill (table 1) in 1979 resulted in average yields of 38, 29, 25, and 39 bu./a. for the early plantings at Brewton, Fairhope, Headland, and Monroeville, respectively. The average yields at Fairhope were 15 bu./a.lower in 1979 than in 1978 and this reduction can be attributed to damage by hurricane Frederic.

The full- to late-season varieties have tended to yield better than early varieties .in southern Alabama for the past 5 years. This has not held :true for Prattvil Ie and Marion Junction in central Alabama. However, the early. varieties- (Maturity Groups V & VI) have out yielded the full- and .late-season varieties (Maturity Group VII & VIII) at the early May planting date... The very early.. v-arieties Group V at Prattville and Group VI varieties .at Marion .Junction have been the highest yielding varieties at .the early planting for the past 5 years. The moisture stress at Prattville and Marion Junction during late pod:fill in 1979 resulted in both lower yields and smaller seed size than .other locations. The largest seed sizes were produced at Winfield. The full- and lateseason varieties .-yielded more than early varieties at al1l locations at the later planting dates. Table 1.

DATA RECORDED The yield of a crop is the primary factor of production when profits are to be -maximized. Other characteristics which are important .are plant height, height of lowest pod, maturity, lodging, and size and quality .of
seed.

Yield of soybeans was determined by harvesting the two center rows Plot yields were adjusted to of each plot with a small plot combine. 13% moisture and converted to bushels (60 pounds) per acre. First bloom was as the date when there was one flower at any node on 10% of the plants. Maturity was rated as the date. when the pods were dry and most of the leaves had; dropped. Under most conditions, the stems.were also dry. Harvest date was approximately 7-10 days later than maturity date. Lodging was based on. a scale of 1 to 5 according to the.following' criteria, see page 5 for illustrations: 1 - almost all plants erect. 2either all plants leaning slightly (less than 450) or a few plants down. leaning moderately (approximately 45 ° ) or 25 3 - either all to 50% of the plants down. 4 - either all plants leaning (more than 450) or 50 to 80% of the plants down. 5 - all plants down.

Shattering ratings were based on shattering of the border rows 14

days after maturity. The visual estimates were rated on a scale of 1 to 5 as follows: 1 - no shattering 2 - 1 to 3% shattering 3 - 4 .to 8% shattering 4 - 9 to 19% shattering 5 - 20% or more shattering Plant height was determined as the average length of plants from the ground to the top extremely at time of maturity.

Height of first pod was determined as the average height of the lowest pods from the ground at maturity.
Seed size for each variety was determined from a composite sample of all replications at a given planting date and location. Seed size is reported as grams per seeds. Small, medium, and large seed size will be 8-12, 13-.16, and 17-20 seed, respectively, and will have approximately 3,800 to 5,700, 2,800 to 3,500.. and 2,300 to 2,700 seed per pound, respectively.

Seed quality was based on a rating from 1 to 5 according to the following scale: (1) very good, (2) good, (3) fair, (4) poor, and .(5) very poor. The factors considered were development of seed, wrinkling due to late harvesting and to excess rain. Purple stain ratings were given to seed samples on a scale of 1 to 5 as follows: 1 - no purple staining 4 - 9 to 19% staining 2 - 1 to 3% purple staining 5 - 20% or more staining 3 - 4 to 8% purple staining

Northern Alabama The.:tests in northern Alabama were located on Decatur clay loam at Belle Mina, Hartsells fine sandy loam at Crossville, and Savannah fine sandy loam at Winfield. varieties for this :area. Soybeans of Maturity Group VI are full season Varieties of Group VII maturity tend to be

taller and later maturing in northern Alabama than at more southern locations. Thus, lodging may be expected for Group VII varieties in

northern Alabama; lodging was a problem in 1979 at Crossville and Winfield for the Group VII and VIII varieties. Lodging has been

severe for 3 and 4 of the past 5 years at both Crossville and Belle Mina, respectively, and the taller full-season Group VI and later It has been the shorter varieties

varieties have not yielded well.

of Group V.maturity that have been the.highest.yielding varieties in early plantings at .Crossville and Belle Mina. Five varieties from Maturity Group IV were in the northern Alabama tests in .1979. These varieties matured in late August at Winfield, This

early September at Belle Mina, and mid September at Crossville. early maturity at Winfield was .a

problem in 1979 as there was 3.25

inches of rain during the: period :when these varieties should have been harvested which resulted in severe shattering and loss of yield. Coker 156 and Essex have .been the highest yielding varieties for the past 5 years at Crossville and .Belle Mina with 36 and 42 bua., respectively. Essex out yielded the next varieties Coker 156 and Forrest For late June planting at Crossville five year Bragg, and Coker

at Belle Mina by 7 bu/a.

average yields of 33 bu/a were obtained from Hutton, 156.

At Prattville, Essex has produced slightly better yields than other varieties over the past 5 years, but its leaf drop and maturity tend to be erratic in central and southern locations. Rainfall of 2..5 inches during the period from August 15 to September 26 resulted in very low yields (14 buIa.average) for all entries in the first planting at Prattville.

Southern Alabama The tests in southern Alabama were on Benndale sandy loam at Brewton, Malbis fine sandy loam at Fairhope, Lucedale sandy loam at Monroeville , and Dothan sandy loam at Headland. Soybeans of Maturity

Group VIII are full season varieties in the southern Alabama locations. For a full season variety to yield well it must have good rainfall during pod fill period (usually during September and early October). As can

be seen from table 1, there was excellent rainfall at all southern locations for 4 of the past 5 years at Brewton and Headland, 3 of the past Because

4 years at Monroeville, and all of the past 5 years at Fairhope. of excellent rainfall during pod fill

over the past 5 years the leading

4 to 5 varieties at each location are Maturity Group VII or VIII varieties. Full season Group VIII varieties Hutton, Coker 338, and Cobo have been consistent high yielders at both Brewton and Fairhope. Group VII varieties

Ransom and Bragg were frequently among the five or six top yielding varieties in the southern locations for the past 5 years. leading Group VI variety followed southern locations. Coker 156 has been the in

by Tracy, Centennial, and Davis,

Varieties in earlier maturity groups such as Group V have

consistently been the lower yielding entries over the past 4 of 5 years. In 1979 soybean yields at Fairhope were 15 bu./a.less than the average yields from the 1978 test. This was due to damage from hurricane Frederic.

The full season variety yields showed the greatest yield reduction for the two years.

Recent entries that have performed well for the past 3 years were Cokers 237 and 448 at Brewton, Coker 237, Ga Soy 17, and Terra-Vig 708 at Fairhope,

and Coker 488, Ga Soy 17, RA 700A, and Terra-Vig 708 at Monroeville. For the past 2 years Braxton and Dowling were high yielding lines at' Brewton (early planting), Fairhope, and Monroeville. Recent entries that performed well in southern Alabama in
1979 were McNair 700 and Tracy M.

These entries were among the top

three yielding entries in one or more of the four southern locations with McNair 700 yielding 45 bu../a.at Monroeville.

Soybean Yields on Cyst Nematode Infested Fields The soybean cyst nematode, Heterodera glycines, is a small microsnap beans,

scopic round worm which attacks the root systems of soybeans, lespedeza, common vetch, and lupine.

In July of 1972 the Alabama State Department of Agriculture and Industries indicated.that the soybean cyst nematode had been found in a soybean field in Escambia. county. By October, 1977 Dr. F.A. Gray of

the Alabama .Cooperative Extension Service had indicated the soybean cyst nematode had been found in soybean fields in 23 counties in Alabama. In 1979 two field tests using from 11 to 12 soybean varieties were placed on two fields on which the soybean cyst nematode had been found. One test was planted June 15, 1979 on the Moody farm near 1979

Stevenson in Jackson county and another test was planted June 16, on the Engle Farm near Summerdale in Baldwin County.

The tests contain and

5 and 4 replications of each variety at each location respectively, plots were four rows with 30 or 36-inch row wide spacing, and 23 feet long.

respectively,

The varieties used are listed in tables61 and 62.

The varieties that have resistance to the Race 3 cyst nematode are Centennial, RA 604, RA 680, and D74-7741 (Group VI maturity) and Bedford Bedford is also resistant to Race 4 County However,

and Forrest (Group V maturity). of the cyst nematode.

The yields were good frorim the Jackson table 61.

location showing a good response to cyst resistance,

the very low yields of the cyst resistant varieties in the Baldwin County field, table 62,were due to a severe problem of peanut root-knot nematode Meloidogyne arenaria. to this root-knot nematode. The variety Centennial is not resistant Bedford and Forrest have fair resistance

to this root-knot nematode but are not well adapted to southern Alabama.

Soybean Protein and Oil Percentage& Soybean protein and oil contents were determined on samples taken from the 1977 and 1978 variety by planting date studies in northern, central, .and souther.n Alabama. 93 . These are shown in tables 84 through

Protein and. oil content of soybeans grown at Crossville, Alabama

were 43 and 22%. respectively, at the earl y May plantingdates and decreased to 41 and 20%, respectively, by .late June dates in 1977. The corresponding protein and oil contents in 1978 were 44.1 and 19.6% respectively for early May planted soybeans and 42.1 and 19.9% for late June plantings. This decrease in protein contents with delayed

plantings. was simi.lar at. Winfield 44.6 to 41.8%, Marion Junction 43.9 to 42.7% and Prattville 45.2 to 40.2%. However, the average protein

content was similar at Brewton with 41.8 and 42.2 for early and late plantings respectively. With the .exception of the early planting date
