The Variance Of Intraclass Correlation Involving Groups With One Observation, L.A. Swiger, W.R. Harvey, D.E. Everson, K.E. Gregory

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

An approximate formula is derived for the variance of intraclass correlation when unequal numbers of observations per group occur. The effect on the variance of t of adding groups with single observations is examined using the formula and results obtained by empirically generating data on a computer. The empirical results indicate that the approximate formula is satisfactory over the range of numbers used.

Adding a group with fewer than the average number of observations per group tends to reduce Vt by increasing the degrees of freedom for groups by one, but tends to increase Vt by decreasing the average precision …

Preserve And Use Tobacco Stalks, George D. Corder

Agronomy Notes

When Kentucky's 1964 tobacco crop is stripped , there will be about 176,000 tons of stalks in and around stripping barns. There will be more than $2 million worth of nitrogen, phosphorus and potassium in them.

If these stalks are left outside the barn and exposed to winter rains, 61 percent of the nitrogen, 38 percent of the phosphorus, 83 percent of the potassium and 41 percent of the organic matter may be lost.

Use Of Phosphate Fertilizers And Bedding To Preserve Manures, George D. Corder

Agronomy Notes

Superphosphate fertilizers added to farm manures as they accumulate in barns, feed lots, and loafing areas will reduce the loss of nitrogen as gaseous ammonia.

Farm Manures, George D. Corder

Agronomy Notes

More than 16 million tons of farm manures valued at more than $47 million are produced on Kentucky farms each year.

Almost half of these manures accumulate in barns, feedlots, and loafing areas. A large part of this will accumulate in these areas between now and pasture time next spring. These manures must be removed from time to time and the cost of handling is unavoidable. Preserving their value and using them wisely on crops and soils that benefit from them will give a fair return on handling costs.

Agronomy Notes, No. 19, George D. Corder

Agronomy Notes

A Test Ban Treaty designed to stop nuclear explosions above ground was signed. World tension was eased. Fear of radioactive fallout was lessened. The Chinese have the atomic bomb. They did not sign the Test Ban Treaty. World tension is on the up-swing.

What has all this to do with agriculture in Kentucky?

Biochemical Changes During The Growth Of Fungi: I. Nitrogen Compounds And Carbohydrate Changes In Penicillium Atrovenetum, David Gottlieb, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Changes in the biochemical constituents of cells were studied during the growth and development of Penicillium atrovenetum. Growth of the fungus, as measured by the dry weight, could be divided into four phases: lag, log, stationary, and death. The percentages of total nitrogen, cold trichloroacetic acid-soluble nitrogen, ribonucleic acid (RNA), and protein increased to a maximum during the lag phase, and subsequently decreased as the fungus aged. The percentage of deoxyribonucleic acid (DNA) was always slightly higher in the spores than in the mycelium. The DNA in the mycelium decreased in the lag phase, and then increased slightly to …

Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The role of organic matter in the growth of plants has been a subject of much investigation and controversy since the sixteenth century. During the early era, decomposition of plant residues and green and animal manures provided a primary source of minerals for plant growth. In addition, beneficial effects on soil structure and water-holding capacity were attribute to the presence of organic matter. With the development of agricultural chemistry culminating in the work of Liebig in the nineteenth century, it was discovered that plants could make satisfactory growth in the absence of added organic matter if suitable kinds and amounts …

Culture And O-Hydroxycinnamic Acid Content Of Excised Melilotus Roots, Larry G. Williams, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Excised roots of biennial sweetclover were successfully cultured through repeated transfers on a modified White's medium solidified with agar. Roots also grew well in shaker-agitated liquid cultures over the pH range 4.5 to 7.0. Exposure of the cultures to bright illumination resulted in submaximal growth. No net synthesis of o-hydroxycinnamic acid was observed in the cultured roots.

Depletion Of Subsoil Moisture By Apple Trees And Other Woody Species, C. C. Wiggans

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This project began in 1934 and ended in 1955. The work of Kiesselbach, Russel and Anderson indicated that depleted subsoil moisture might be the reason for the loss of many orchards and the injurious effects noted on native woody forest species. Most of the work in apple orchards was done at the University Fruit Farm at Union, Nebraska. Samples were also secured from commercial plantings of apples and other woody species in areas ranging from Rulo, near the Kansas-Nebraska border, to Florence, just north of Omaha, to Lincoln and several points in central Nebraska.

Borax, Borates, And Other Boron-Carrying Compounds, Harold F. Miller

Agronomy Notes

Boron is available on the market in a number of different compounds. Since the amount of boron contained in each compound is different, the concentration will determine the rate required per acre. Frequently, all of these boron-containing compounds are erroneously referred to as borax (11.36 percent boron).

Organic Toxicity, Jones H. Smiley, Ira E. Massie

Agronomy Notes

In recent years there has been much discussion on the subject of organic matter toxicity and its relation to the severity of black root rot of tobacco. Organic matter toxicity is due to or at least related to toxins produced during organic matter decomposition.

Using Fertilizer Nitrogen Effectively On Grain Crops, Robert A. Olson, A. F. Dreier, C. Thompson, K. Frank, Phillip H. Grabouski

Department of Agronomy and Horticulture: Faculty Publications

Fertilizer nitrogen is necessary for the efficient production of grain crops throughout the midwest. Farmers have recognized this need by tremendous increases in nitrogen consumption duhng the past decade.

Fertilizer nitrogen where needed for optimum yield usually increases slightly the total water used by the crop. The water required in making this optimum yield, however, is used a good deal more efficiently than where nitrogen is omitted. Nebraska studies on fertilizer economy have demonstrated nitrate leaching losses in some cases, especially serious on sandy soils of low water holding capacity and with irrigation. Strong circumstantial evidence also suggests denitrification of …

Occurrence Of O-Hydroxycinnamic Acid In Species Of Melilotus And Trigonella, Herman J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Leaf samples from available species of Melitotus and the closely related genus, Trigonella, were assayed for free as well as glucosidically bound cis- and trans-o-hydroxycinnamic acids. A qualitative evaluation of β-glucosidase activity also was made. In none of the species were appreciable quantities of the free acids detected. Of the 19 species of Melilotus sampled, 14 contained high levels of the o-hydroxycinnamic acid glucosides, one (M. infesta) was intermediate, and four were essentially free of these glucosides. The intermediate level in M. infesta is unlike that in any other species of Melilotus, …

Fertilizer-Insecticide Mixtures On Corn, R. L. Miller, George D. Corder

Agronomy Notes

Soil fertility and insects are major factors that affect corn yields. The proper kinds and amounts of fertilizers and insecticides properly placed will make corn production more economical on fields where either or both are needed.

Fertilizer-Insecticide Mixtures On Tobacco Plant Beds And Fields, George D. Corder, R. L. Miller

Agronomy Notes

Fertility and insect control programs have a major influence on tobacco production. The proper amounts and kinds of fertilizers and insecticides properly placed will make production more economical on beds and fields if either or both are needed.

Is a fertilizer-insecticide mix the best way to meet the fertility needs and t he insecticide needs on tobacco? The following questions and answers should help show how the decision was reached that this method is not recommended.

Hyperparasitism, Michael G. Boosalis

Department of Plant Pathology: Faculty Publications

Much of the research on hyperparasitism has been of a descriptive nature, based primarily on studies with dual cultures in synthetic media. The main contributions from these investigations concern the host range of the parasite, the mode of penetration and infection, and the morphological changes of the host and the parasite resulting from parasitism.

More recent studies on hyperparasitism emphasize the effect of environmental factors, especially nutrition, on the susceptibility of the host. Research on the physiology of hyperparasitism has been limited. Nevertheless, this important aspect of the problem should continue to receive increased attention as hyperparasitism is extremely amenable …
