Trials were conducted at 11 locations in Mississippi in 1994-5. Public varieties were selected by the Technical Advisory Committee for evaluation at each location.

Procedures

Experimental design for each crop species at each location was a randomized complete block with four replications. Plots consisted of 7 rows spaced 7 inches apart and 20 feet long. Cultural and pest control practices used in each trial were as follows. Plots were limed and fertilized with P2O5 and K2O according to soil test recommendations. Nitrogen was applied at 20 pounds per acre at planting and 80 and 45 pounds per acre in late February for wheat and oats respectively. Foliar fungicides were not applied to insure that varieties were evaluated under conditions of maximum disease pressure. Herbicides, Hoelon and Harmony for wheat and Harmony alone for oats, were applied at each location, as needed, for broadleaf and grass weed control.

Source of Seed...Seed of all private entries were supplied by participating companies. Seed of all public varieties were Breeder or Foundation Seed from the state that developed the variety.

Planting Rate...All seeds were packaged for planting at the rate of 20 seeds per foot of row for both crops. Plots were planted with a cone, spinner-divider planter.

Yield...A plot combine was used to harvest the total plot area after the plots were trimmed to a standard length. Harvested seed were converted to bushels/acre (60 pounds/bushel for wheat and 32 pounds/bushel for oats).

Heading Date...The date when 50 percent of the heads were extended above the flag leaf.

Plant Height...The height of plants was measured from the soil to the top of the spike or panicle.

Lodging...Lodging was rated on a scale of 1 = almost all plants erect, 2 = all plants leaning slightly or only a few plants down, 3 = all plants leaning moderately or 25% to 50% of plants down, 4 = all plants leaning considerably, or 50% to 80% of plants down, and 5 = all plants down.

Seed Test Weight...The test weight for each variety was determined from a composite sample from all replications.

Disease Ratings...All varieties were rated for development of leaf rust and Septoria leaf and glume blotch according to James' Manual of Assessment Keys for Plant Diseases. At growth stages 10.5 (spikes emerged) and 11.1 (milky ripe), 10 plants were selected at random from each plot at each location. The percentage of leaf area affected by each disease on the flag leaf was recorded. From these data an assessment was made of the overall disease response of each variety.

Production

Wheat can be grown in most counties in Mississippi for grain and for grazing. Over the past few years, wheat acreage has declined as a result of adverse fall weather, disease intensity, and price received for grain by farmers. Oats can be grown in most counties of Mississippi and be used as farm feed grain or grazing.

Wheat yields generally range from 30 to 40 bushels per acre. Under favorable weather and management conditions, wheat sometimes yields as high as 70 bushels per acre. Although wheat is cold tolerant, during severe winters it may be killed or damaged. Oats are also subject to winterkill or damage.

Cold Requirements

Winter varieties of wheat require a certain amount of cold weather (about 35 °F) before the plants will form reproductive structures (seed heads). The period of time varies with variety, but somewhere between four and nine weeks of low temperatures are required for seed-head formation. Most of the wheat varieties planted in the area require low temperatures to reproduce; oats do not.

Land Selection and Preparation

Wheat and oats are adapted to many soil types throughout the state. However, these grains will not tolerate poor drainage conditions and still produce an economical yield. Internal as well as external drainage are equally important to wheat and oat production. Also, these grains will not produce economic yields on very thin, badly eroded soils.

Good seedbed preparation will insure a good, fast stand of small grains. Wheat and oats may be planted with a drill or broadcast into a prepared seedbed. A grain drill should be used in no till or minimum till situations. Seeding rates should be increased when planting in poor seed beds.

There is some interest in seeding grains in standing soybeans. This method of sowing involves greater risk for stand establishment. When this method is used, grain should be seeded as soybean leaves turn yellow and about 10% of the leaves have dropped. Seeding rates in standing soybeans should be increased.

Varieties

When selecting wheat varieties, farmers should refer to the Wheat and Oat Variety Trial Publication. It is an excellent source for review when considering which variety should be grown. The publication lists private and public varieties that are tested at different locations across the state each year. Pertinent agronomic data are recorded for each variety at each test location. Disease ratings for varieties also are included. A variety with good agronomic and disease characteristics should be selected from the information supplied. It is also best to select a variety that has performed well in many test locations. The average yield table will provide this information.

Seeding Rates

Seeding rates should be based upon a set number of seed per foot of row. Use the low rate when planting at the normal times and the upper rates when planting at a later date or when planting conditions are poor. For seven- to nine-inch drill spacings, the normal seeding rate is 20 seeds per foot of row. Wheat seed normally have from 12,000 to 16,000 seed per pound. Normal seeding rates for drill planting vary from 70 to 90 pounds of seed per acre, depending upon the variety selected and planting time. When seeds are broadcast and covered with a field cultivator, 90 to 100 pounds should be planted. If aerial seeding in standing soybeans is practiced, then apply 125 pounds per acre. Aerial seeding into standing soybeans is not a recommended practice. Seeding rates in seed per foot for oats is similar.

Planting Dates

Planting before recommended planting dates does not insure better yields and sometimes results in increased problems (freeze injury, aphids, Hessian fly, and disease problems). If grazing is not a consideration, planting on the late side of the recommended time usually results in fewer insect and disease problems. The three area planting dates are:

North Mississippi October 1 to November 15
Central Mississippi October 15 to November 25
South Mississippi November 1 to December 10

Disease and Disease Resistance

Several diseases may affect wheat and oat plants in Mississippi. Leaf rust, stem rust, Septoria leaf and glume blotch, and several head diseases are very common. Planting resistant varieties is the most practical, economical, and effective control. However, chemical control is recommended for certain diseases in certain circumstances. For more specific information, refer to Extension Plant Disease Dispatch M-123.

Seed Treatment

Proper seed treatment reduces the number of disease causing organisms on the surface of the seed and loss due to seedling diseases. Several recommended seed treatment fungicides are Captan, Vitavax, Terra-Coat, Dithane, Baytan, and others. These materials are available in various formulations and under several brand names. Seed may already be treated when purchased, or fungicides should be applied according to label instructions.

Insects

Several insects that can cause economic damage to wheat and oats are Hessian fly, aphids (including greenbugs), armyworms, cutworms and other soil insects, and grasshoppers. Plant resistant varieties in areas where Hessian fly is a problem. Refer to Mississippi Cooperative Extension Information Sheet 1160 for threshold and insecticide information for control of the other pests listed above.

Fertilization

Apply phosphate and potash according to soil test recommendations. Soils testing high in phosphate and/or potash will not need any additional material. Soils testing medium should receive a maintenance application of 30 pounds, and soils testing low should receive 60 pounds of P2O5 and K2O per acre.

If soybeans are to follow a wheat crop in heavy soils (clays, clay loams, and silt loams), phosphate (P) and potash (K) for the soybean crop may be applied before planting the wheat. This practice of applying P &K in the fall for both crops on sandy and sandy loam soils is questionable as far as K is concerned, because some K may be lost through leaching on lighter soil types.

Some nitrogen (N), 20 to 30 pounds per acre, should be applied before planting unless following soybeans are planted on soils containing two percent or more organic matter. In these cases no pre-planting nitrogen is necessary. If the previous crop were grain sorghum, 30 to 40 pounds of pre-plant nitrogen is recommended.

Wheat should be topdressed with 80 to 100 pounds of N per acre in mid February or early March. If nitrogen is aerially applied, applications may be split--one in February and another in early March to improve coverage and use efficiency. Soil pH should be 5.6 or higher. Soil test and lime according to recommendations.

Weed Control

Mississippi Cooperative Extension Service Publication 1344, Grain Crops, provides detailed information for controlling weeds in wheat and oats. Wild garlic, dock, and many other broadleaf weeds can be controlled using the herbicide Harmony Extra. Use 2,4-D for economical control of wild onion and many broadleaf weeds. Wild garlic and wild onion may not be killed with the rates of 2,4-D that can be used without injury to wheat. This treatment normally causes the garlic and onion plants to curl down and reduces the amount of bublets that get into the grain during harvest. Banvel (or Dicamba plus 2,4-D) is a good treatment if legumes, such as winter peas and vetch, are a problem. Ryegrass is best controlled using Hoelon either pre-emergence or early post-emergence. Most treatments can be applied post-emergence in liquid nitrogen. However, nitrogen rates should be below 50 pounds of nitrogen per acre, and air temperatures should be below 60 °F to reduce the danger of injury to the wheat.

Management for Grain Following Grazing

Many farmers graze small grains during the fall and winter and then harvest a grain crop in the spring. If maximum grain yields are to be made, livestock must be removed in mid February to early March when the nitrogen topdressing is applied. At about this time, the seed heads are beginning to form, and in a short while, stem elongation will follow. Grazing after stem elongation begins removes the forming seed heads. There will be no initiation of new seed heads, and yield is reduced.

Harvesting

Wheat and oats will mature in late May to early June. Most harvesting occurs in early June. If drying facilities are available, grain should be harvested at 16 to 18 percent moisture and then dried. Harvesting at this moisture content allows harvest 10 days to 14 days earlier than if grain is allowed to dry to 12 to 13 percent moisture in the field. When grain is allowed to dry in the field, there is a probability that quality may be reduced and lodging may occur due to a prolonged rainy period. If grains are to be double cropped with soybeans, this could be a great advantage for bean planting.

Weather Summary by Location

Locations 1 and 2--Delta Branch: High rainfall amounts in October delayed ground preparation and planting. Heavy rains after planting packed and sealed the sandy loam site, causing the seed to rot. The sandy site was not replanted due to the late first planting and rain. The clay site had poor emergence, but no cold injury was noted. Heavy damage from birds feeding was observed in many plots.

Location 3--North Mississippi Branch: Good moisture at planting and timely rains allowed quick emergence of all varieties. No cold injury was observed due to mild winter temperatures. A hail storm during the spring caused lodging of some varieties.

Location 7--Black Belt Branch: Near normal rainfall occurred during November 1994 for good stand development. Following stand establishment, growth progressed normally due to moderate temperatures and sufficient rainfall during February and March. Spring weather conditions were optimum for wheat development at Brooksville.

Location 8--Brown Loam Branch: Adequate soil moisture and warm temperatures resulted in excellent stand establishment of both wheat and oats. Warm temperatures from December through March produced good tillering and plant growth. Heavy rainfall in early March and again in late April caused lodging in some varieties. Ryegrass control was excellent, and insects were not a problem during the growing season. Diseases were light to moderate, developed late in the growing season, and did not appear to affect yield.

Location 9--Coastal Plain Branch: Adequate soil moisture following planting allowed quick germination and emergence. Above normal soil and air temperatures during the winter months allowed for good growth. Spring conditions were optimum for grain development, and disease did not appear until late and did not reach harmful levels. Birds continue to be a menace to oat varieties every year.

Location 11--Mississippi State: An excellent stand was established quickly. All plots looked good at the end of February. By April there were noticeable differences in the plant growth within plots. The yields were not as high as the appearance indicated. The oat varieties were extremely short and did not appear as vigorous as they should. This location had no bird damage.

Notes on Locations 1, 2, 4, 5, 6 and 10:

The tests at the Pontotoc and Verona locations were not planted due to excessive moisture and lack of time for ground preparation. As the weather summary indicates, the Stoneville loam test never developed a stand. The Stoneville clay test looked good but because of erratic stands, late planting, and bird damage, only two replications were usable, which resulted in high CVs. The Poplarville test was planted but not harvested because of erratic stands.

Only two oat locations were harvested, and yields were low. The other locations had little or no seed produced by the plants, and birds ate what was produced.
