Tips For Small Grain Seeding, Morris J. Bitzer, James H. Herbek, Dennis M. Tekrony

Agronomy Notes

TEST YOUR SOIL AND SUPPLY THE SUGGESTED LIMING AND FERTILIZER MATERIALS.

A soil test is the first step to profitable small grain production. A pH of 6.0 to 6.5 is best, and nitrogen should be applied both in the fall and spring. If your small grains are part of a double cropping system the P and K requirements for both crops should be applied in the fall.

Uptake And Distribution Of Mineral Elements By Burley 21 Tobacco As Influenced By Nitrogen Nutrition And Suckering Practice, J. L. Sims, W. O. Atkinson

Agronomy Notes

Knowledge of nutrient content of tobacco and of removal of nutrients from soil is essential to developing sound fertilization practices for tobacco. Quantities of nutrient elements taken·up by tobacco vary widely. This is because of variations in variety, soil fertility level, fertilizer application, soil moisture, plant population, and other environmental and cultural factors . We conducted the present study to determine the effects of applied N and suckering practice on the content of mineral elements in certain plant parts of burley tobacco.

Soil Surveys In Kentucky, Harry Hudson Bailey, Robert L. Blevins

Agronomy Notes

Soil surveys are a scientific inventory of the soil and land resources of an area. They locate the different kinds of soils and provide information as to their physical and chemical properties. The survey reports also contain tables and charts showing the use of the soils for agriculture, engineering, community development, recreational areas, woodland, and wildlife.

Today there is some type of soil survey activity in every county of Kentucky. The University of Kentucky has cooperative soil survey arrangements with the USDA Soil Conservation Service and the U.S. Forest Service.

Forage Sorghum And Forage Pearl Millet Performance Lexington, Kentucky 1970, Roy E. Sigafus

Agronomy Notes

Most livestock producers, especially dairy farmers, have a need for a high quality roughage in summer when cool-season grass pastures are normally low in production. Alfalfa and clover-grass mixtures grazed rotationally, and small grain and "grass" silage or hay are common sources of summer feed . There is an increasing interest, however, in forage sorghums and forage millets for grazing or green-chop .

Effect Of Nitrogen Fertilization On Yield Of Burley Tobacco, J. L. Sims, W. O. Atkinson, Jones H. Smiley, Allen M. Wallace

Agronomy Notes

Relatively large amounts of nitrogen from fertilizers and manures commonly are used in burley tobacco production. Growers are currently estimated to apply between 150 and 400 pounds of actual N per acre. Fertilization of burley with nitrogen significantly affects the physical and chemical characteristics of cured leaf and produces changes in yield and value. On most soils, leaf yields usually are increased by applications of N fertilizer, but the amount of yield increase per unit of applied fertilizer N varies widely between soils. High rates of N applied preplant or at planting often retard early plant growth, delay maturity, and …

Why Does Second-Cutting Red Clover Hay "Slobber" Animals, J. Kenneth Evans, A. S. Williams, D. E. Labore

Agronomy Notes

For years, farmers have noticed the slobbering of animals after feeding second-cutting red clover hay. Severity of this effect, however, has varied from year to year. Questions asked many times are what causes the slobbering and what can be done about it? To get the answers available, let's go back about 37 years into something which appears to be totally unrelated to slobbering and follow research which has been done on a fungus, which causes a disease of red clover.

Yield And Value Of Burley 21 Tobacco As Influenced By Nitrogen Nutrition, Suckering Practice, And Harvest Date, J. L. Sims, W. O. Atkinson

Agronomy Notes

An experiment was conducted in the field during 1966 on Maury silt loam soil to obtain information of the effects of agronomic factors on yield and value of Burley 21 tobacco . Ammonium nitrate fertilizer at varying rates, and concentrated super-phosphate and potassium sulfate at constant rates , were broadcast and disked in after plowing and before transplanting. All plots received irrigation water (sprinkler system) to supplement rainfall when soil moisture dropped below 60% of available moisture-holding capacity. Sucker control practices utilized were (a) no topping - no suckering, (b) topping - no suckering, (c) topping - hand suckering, and …

York soybean, a pure line selection developed by the Virginia Agricultural Experiment Station from a cross of Dorman X Hood, was recently added to the recommended list for Kentucky. It was released jointly in 1967 by Virginia, Maryland, and North Carolina.

Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.

KWRRI Research Reports

The chemical composition of algae grown in batch culture depends mainly on environmental conditions, nutrient availability, presence of predators, cell age, and species. The effects of nutrient availability and cell age on the composition of three unialgal cultures (algae + bacteria) and one hetergeneous culture (algae + bacteria + microscopic animals) were evaluated. The cultures were grown in batch culture under both nutrient-abundant and nutrient deficient conditions and the changes in compositions were observed. Luxurious uptake where nutrients are incorporated into cellular protoplasm at levels greater than those necessary for growth, and super-luxurious uptake, where some nutrients are stored rather …

Fertilizing No-Till Corn, John L. Ragland, John Masterson, C. R. Belcher

Agronomy Notes

Results of an experiment conducted in 1968 at Princeton, Kentucky on low phosphate soil showed that surface-applied phosphorus was sufficiently available to no-till corn to produce good yields. This experiment was repeated again in the 1969 growing season with the results well in line with those reported for 1968 in Agronomy Research (Misc. 377) pages 41-43.

No-Tillage -- Suitability To Kentucky Soils, Robert L. Blevins

Agronomy Notes

As more farmers adopt no-tillage methods of farming the questions arises whether or not all soils are suited to this practice. To get an idea of how well suited the no-tillage method of corn production is to wide variety of soils, we made a survey in five different physiographic regions of Kentucky in 1969.

Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

1. Transfer between the plant leaf and the canopy …

The Economic Value Of Streams For Fishing, Dennis Hugo Bianchi

KWRRI Research Reports

The pressures of urbanization and industrialization are gradually destroying stream fishing sites while at the same time producing an increased demand to serve a greater population. Reservoir construction is one cause behind the diminishing availability of stream fisheries. The recreational value of the stream fishery lost should be deducted from the value gained through reservoir recreation in estimating net benefits for economic justification. This study utilized information collected from 3321 stream fishermen to derive a method and the necessary empirical coefficients for predicting the number and economic value of the average annual fisherman-days enjoyed along average streams throughout Kentucky.

The Effect Of Nitrogen Rate And Method Of Sucker Control On Dry Matter Accumulation In Different Plant Parts Of Burley 21 Tobacco, J. L. Sims, W. O. Atkinson

Agronomy Notes

Earlier research has shown that higher leaf yields of burley tobacco result from topping and controlling sucker (axillary bud) growth. Suckering practices which provide the greatest degree of sucker control generally result in highest leaf yields . Chemically suckering with maleic hydrazide (MH-30) and other chemicals provides for a higher degree of control than most hand sucker ing practices although hand sucker ing at frequent intervals may produce leaf yields comparable to those from use of maleic hydrazide. High leaf yields resulting from a high degree of sucker control has been attributed to the elimination of the use of photosynthate …

Summary Of Fertilizer Use And Estimated Use Of Plant Nutrients On Tobacco, Corn, Hay And Pastures In Kentucky, Kenneth L. Wells

Agronomy Notes

Nearly 650, 000 tons of fertilizer were used by Kentucky farmers during the first half of 1969. Plant food content (N+P₂O₅ + K₂O) was 38%, or nearly 247,000 tons. Slightly over half (58%) was sold in bagged, one-third (33%) in bulk, and 8% in fluid form. Mixtures made up 70% of the total tonnage, and materials made up 30%. The statistics tabulated below show a more detailed breakdown of the fertilizer tonnage used.

Irrigating Corn On Well-Drained, Limestone-Derived Soils, John L. Ragland, J. C. Redman

Agronomy Notes

In trying to determine if it would pay Kentucky farmers to irrigate corn, one of the most important steps is to ascertain the long-time average yield increases to be expected from supplemental irrigation. The yield data reported below are the results of an experiment applicable for a fairly large group of soils occurring in Kentucky.

Molybdenum Recommendation For Legumes, J. L. Sims, Warren C. Thompson, S. H. Phillips

Agronomy Notes

Molybdenum is recommended in Kentucky for legumes (soybeans, alfalfa, clovers and other forage legumes) beginning in 1969. The application should be made as a seed treatment and at the rate of 0.4 to 0.8 (4/10 to 8/10) ounces of molybdenum per acre. Molybdenum is recommended only on soils testing less than pH 6.2.

The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates

KWRRI Research Reports

Development of a large multi-purpose reservoir within the area of their jurisdiction may affect property ta.x revenue and expenditure of county governments and school districts. Privately owned land sold to a federally sponsored reservoir is not subject to property taxes because of the doctrine of intergovernmental immunity. Local officials often assume that this loss of assessment will reduce their tax revenue and thereby their fiscal ability to provide an acceptable level of government services. They may also expect the influx of construction workers or the disruption of existing facilities to increase the cost of providing these services. The study approaches …

Airplane-Seeded Wheat – Aid To Double Cropping, John Watts, S. H. Phillips

Agronomy Notes

Airplane-seeding of wheat has been increasing since its start in 1965 in Fulton County, Kentucky. Over 20,000 acres were seeded in the fall of 1968, with the acreage concentrated in the Purchase and Bowling Green areas.

Farmers report these advantages for aerial seedings: (1) early establishment of small grain; (2) similar seeding cost as compared to drilling; (3) labor use in normal seeding operations diverted to other farm operations.
