Phosphorus And Potassium Elemental Or Oxide, Harold F. Miller, George D. Corder

Agronomy Notes

Soil tests for phosphorus (P) and potassium (K) are reported on the elemental basis by all soil testing laboratories (state and county) in Kentucky.

Field Trials With Zinc On Corn, H. F. Miller, S. H. Phillips, C. E. Wyatt

Agronomy Notes

Zinc deficiency in corn has been found in isolated instances in Kentucky during the past few years. Usually the deficiency is found in fields having a high pH or in high-phosphate soils with somewhat lower pH values. At present zinc deficiency in Kentucky soils does not appear widespread enough to justify recommending its application except where known deficiencies exist.

A New Black Shank Resistant Hybrid, Jones H. Smiley, Ira E. Massie

Agronomy Notes

Seed of a new black shank resistant burley hybrid will be available to growers in 1964. This hybrid is especially for farmers who cannot rotate their tobacco land and . thus, are forced to set their crop in a black shank infested field. The hybrid is a cross between two black shank resistant varieties, MS L8 and Burley 37. The female parent , MS L8, carries black shank resistance from a wild relative of tobacco.

Calcium Deficiency Symptoms In Burley Tobacco, Jones H. Smiley, Ira E. Massie, George Everette

Agronomy Notes

Calcium is an element required by all higher plants in relatively large quantities. It appears to be closely related to the formation of buds and flowers.

Calcium is usually available in sufficient quantities in Kentucky soils to produce a normal crop of tobacco. However, when certain varieties of burley tobacco commence to bloom and produce suckers, the tips of the calyx lobes of the flowers may turn brown and die and the edges of the small leaves of the suckers may be necrotic, resulting in irregularly shaped sucker leaves. In severe cases the apical bud may be killed. These calcium …

Tobacco Stalk Production, Value And Use, George D. Corder, Harold F. Miller

Agronomy Notes

When Kentucky farmers finish stripping the 1963 tobacco crop they will have 176,000 tons of tobacco stalks worth $2 million on their farms.

These stalks will contain 9.8 million pounds of nitrogen, 932,000 pounds of phosphorus (2 million pounds of P₂O₅) and 13 million pounds of potassium (15.6 million pounds of K₂O). Equal amounts of these plant nutrients bought in commercial fertilizers in 1963 would have cost more than $2 million.

Changes In Soil Ph Caused By Heavy Nitrogen Fertilization, W. O. Atkinson

Agronomy Notes

Ammonium nitrate, ammonium phosphate, ammonium sulfate, urea and anhydrous ammonia leave acid residues, thus tending to make the soils more acid. The degree to which soil pH may be affected and the persistence of such changes for a silt loam soil is shown in the table below. The same amounts of phosphorus and potash were applied to all plots, and the different amounts of nitrogen were supplied from ammonium nitrate. Burley tobacco was the crop grown and the data are for 1963, which was the second consecutive year for the fertilizer treatments. (These were experimental plots and the high treatments …

Agronomy Notes, No. 6, Harold F. Miller, George D. Corder

Agronomy Notes

This fall is an ideal time to apply needed agricultural limestone. Spreading equipment can get over the dry ground with less soil compaction, and limestone applied now can correct soil acidity during the winter months.

Fall Treatment Of Tobacco Beds With Methyl Bromide, Ira E. Massie, George Everette, Jones H. Smiley

Agronomy Notes

Treating tobacco beds with methyl bromide for the purpose of killing weed seed has become very popular in recent years. The gas is effective except on the seed of white clover and when the soil temperature is below 50° F.

Plant Beds, Jones H. Smiley, Ira E. Massie

Agronomy Notes

Due to the occurrence of blue mold and manganese toxicity in some of the plant beds this last spring, it is probably advisable for all growers to select a new site for the 1964 crop.

Blue mold is a fungus disease which sometimes causes severe damage to tobacco seedings just prior to setting time. The fungus will produce heavy-walled spores on the dying or dead leaves. These spores are capable of remaining in the soil at least a year and attacking the next crop of plants if the same site is used again for tobacco plants .

Determine Liming Needs On Tobacco Land This Fall, Jones H. Smiley, Harold F. Miller

Agronomy Notes

There have been far too many reports of manganese toxicity in tobacco this season for a condition which is so easily corrected.

Manganese is one of the minor elements necessary for plant growth, but it is needed in very small amounts. When large amounts are taken up by a tobacco plant, light green or yellowish areas appear between the larger veins of the leaf. In severe cases the plant may be stunted or even die.

Agronomy Notes, No. 1, S. H. Phillips, Harold F. Miller, Verne C. Finkner

Agronomy Notes

This is the first issue of "Agronomy Notes." The Agronomy Department, University of Kentucky, expects to use this publication to inform county agents, other agricultural workers, and leaders on current progress in soils & crops work. The Kentucky Experiment Station will be an important source of information. Information may be drawn from other research. Field trials and observations that show useful information may be reported. The emphasis will be on short timely topics.

Barley - Oat Varieties, 1963, S. H. Phillips

Agronomy Notes

Selection of barley and oat varieties is important to growers of these small grains. Tests are conducted across Kentucky by the University of Kentucky Agronomy Department to determine yield, winter hardiness, disease resistance, standability, and other characteristics important to efficient production. Planting dates are more important for these two crops than for wheat and rye because of winter freeze damage. The best planting dates for barley and oats run from September 1 to September 20. Later plantings are made in Kentucky but are subject to more damage from cold weather. Increased planting rates in barley tend to improve yield in …

Studies On Antibody Production. Viii. The Inhibitory Effect Of Chloramphenicol On The Synthesis Of Antibody In Tissue Culture, Charles T. Ambrose, Albert H. Coons

Charles T. Ambrose

In 1953 Gale and Folkes (1) observed that chloramphenicol inhibited protein synthesis in Staphylococcus aureus but permitted substantial nucleic acid synthesis to continue. Subsequently, this drug has served as a powerful tool in studies of protein and nucleic acid metabolism in a wide variety of microbial systems. In sensitive bacterial cultures the addition of 30 to 100/~g/ml 0.1-0.31m~) of chloramphenicol results in prompt and nearly complete suppression of protein synthesis (1, 2), while concentrations as low as 2 ~g/ml (0.006 m~) produce 50 per cent inhibition in some bacteria (1). Very low oncentrations also inhibit protein synthesis in cell-free bacterial …

Interim Report On Rural Secondary, Base Stabilization Projects, Robert C. Deen, J. D. Shackelford

Kentucky Transportation Center Research Report

Early in 1962, the Division of Rural Highways selected several base stabilization projects for construction during the 1962 season. These projects were to involve the addition of 1-1/2 to 3 inches of compacted granular base to existing, rural secondary, traffic-bound macadam roads. Since these roads were not intended to be surfaced, calcium chloride and sodium chloride were to be added to the additional granular base material in an attempt to retain or "hold" the aggregate on the road. This treatment was in tended to improve the road and to build up the base over a period of a few years …

Experimental Use Of Thermo-Plastic Pavement-Striping Materials, James H. Havens

Kentucky Transportation Center Research Report

The purposes and objectives of this experimental study are: 1) to evaluate the application and performance characteristics of hot-melt plastic, pavement-striping materials which are presently prominent and known commercially as "Catatherm" and "Perma-Line"; 2) to compare the performance of these materials with the performance of painted stripes applied and re-newed according to the current practices of the Kentucky Department of Highways; and 3) to evaluate the economics of these striping materials in terms of cost-per-mile per-day-of-useful-life, The project is described more fully in the "Proposal...
