Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …

Silage Making In The Lower South-West, A L. Hamilton

Journal of the Department of Agriculture, Western Australia, Series 4

The history of silage making in the South-West of Western Australia is typified by periods of relatively intense activity followed by periods when the activity virtually ceases.

The recent rise in popularity has followed the introduction of machinery or methods which tend to make the job easier to handle, or which improve the quality of the silage.

Take-All Of Wheat On The Esperance Downs : The Effect Of Multiple Cropping, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

A considerable increase in take-all occurred in the second crop of wheat following linseed, oats or vetches at the Esperance Downs Research Station.

THE take-all disease of wheat, caused by the fungus Ophiobolus graminis, has been responsible for many crop failures in the Esperance district during the past 15 years.

In an endeavour to find a practical solution to this problem, a crop rotation experiment was started in 1961 at the Esperance Downs Research Station.

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.

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 …

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.

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 .

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.

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.

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 …

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.

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.

Performance Of Alfalfas Under Five Management Systems, W. R. Kehr, E. C. Conard, M. A. Alexander, F. G. Owen

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This bulletin reports stands, forage yields, and other agronomic data on alfalfas of diverse origin or type tested under five management systems at Lincoln, Nebraska. Narrow-crowned and broad-crowned types were tested. The management systems involved non-irrigated alfalfa-bromegrass tests (a) continuously grazed with steers, (b) cut for hay, and (c) rotationally grazed with sheep; an irrigated alfalfa-bromegrass test rotationally grazed with dairy cattle; and irrigated tests of alfalfas in pure stands cut for hay.

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson

Department of History: Dissertations, Theses, and Student Research

Preface (excerpted)

The primary purpose of this study is tto trace the development of irrigation in Nebraska from the organization of the state as a territory in 1854 through the rest of the nineteenth century. This period covers the first four stages through which irrigation progressed: individualistic, corporate, district, and state. A brief discussion of the North Platte Project is included, however, in order to carry the story into the fifth and final stage--the development of irrigation with Federal aid, as provided for in the Reclamation Act of 1902.

The emphasis of this work is on the irrigation movement and …
