A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The following key to the Nebraska cutworms and armyworms injurious to corn is based upon structural characters supplemented in some instances by color. Not all of the species in this key have been found in Nebraska; some are included because they are to be found in near-by states to such an extent that they probably are present in this state.

Annual Fodder And Silage Crops For Nebraska, W. E. Lyness, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Circulars

The present shortage in the seed supply of all standard varieties of annual forage crops has created a special demand for information concerning their relative productivity and the possible use of substitute crops. This circular reports the yields secured from such crops at the Experiment Station, in an effort to help farmers reach a decision as to which crops should be grown this year for roughage, and which ones especially should have their seed supply increased for use in future years. Feed value and production costs as well as yields should be taken into consideration by the grower.

Ec33-136 Corn In Nebraska, P.H. Stewart, D.L. Gross, T.A. Kiesselbach

University of Nebraska-Lincoln Extension: Historical Materials

Corn is Nebraska's most important crop. Of the nearly 19 million acres under cultivation in the state, over 10 million acres or more than 50 percent is normally planted to corn. This is three times the acreage of wheat, four times that of oats, and ten times that of barley. The 10-year average acre yield of corn for this state is 25.8 bushels compared with 26.9 bushels for the entire United States. Nebraska, with an average annual crop of approximately 258 million bushels, usually ranks third among all states in the total production of corn, being exceeded by Iowa and …

Ec32-134 Sweet Clover Management, P.H. Stewart, D.L. Gross

University of Nebraska-Lincoln Extension: Historical Materials

Sweet clover has made a phenomenal growth in popularity and acreage during recent years. In Nebraska, the production increased from 30,000 acres in 1920 to 1,126,000 acres in 1930, an expansion of over one million acres in a 10-year period. Just a few years ago, when sweet clover was classified as a weed, it was the subject of proposed state legislation to prevent its production and spread. Today sweet clover has a recognized place among standard crops and in rotation systems. The acreage of sweet clover in Nebraska is now practically equal to that of alfalfa and is more than …

Ec30-39 Swine Sanitation, L. Van Es

University of Nebraska-Lincoln Extension: Historical Materials

From the very beginning of Nebraska's agricultural development its farmers have recognized that the production of swine must of necessity accompany the growing of corn. The latter, one of the state's most important staples, cannot be marketed in a more economical manner than after having been transformed into pork, bacon, and lard.

As a result the state has for many years maintained a rather dense swine population mainly divided into large herds kept on relatively small areas of land. This density of population, as well as certain practices in management and selective breeding, has brought about conditions favorable for the …

Rb30-250 Raising Early Lambs From Aged Western Ewes, A.D. Weber

University of Nebraska-Lincoln Extension: Historical Materials

Many farm flocks in Nebraska are comprised of aged western ewes. They are easily obtained because of the state's geographical position with reference to the sheep-producing sections of the West and the leading feeder lamb markets. Nebraska ranks second in number of western lambs fed. This also tends to acquaint farmers with range sheep.

This 1930 research bulletin discusses factors in early lamb production; objects of the experiment, experimental procedure, and experimental data of raising early lambs from aged western ewes.

Rb30-244 Types Of Farming In Nebraska, Harold Hedges, F.E. Elliott

University of Nebraska-Lincoln Extension: Historical Materials

"Type of farming" as used in this bulletin is a term descriptive of a group of farms similar in size and enterprise combination. Thus a group of farms having the same kind, quantity, and proportion of crops oand livestock may be said to be following the same type of farming. The term "type-of-farming area" refers to an area within which there is a high degree of uniformity in the type of farming practicse and in the physical and economic conditions under which production takes place. This should not be understood to mean that there is absolute uniformity either in farming …

Better Rations - More Eggs, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Well-bred and well-fed hens are conceded to be economical producers of a very wholesome food product, eggs, but our hens are not miracle workers and they insist on the right kind of raw material for building the egg. Nebraska poultry growers fortunately have all the natural feeds - corn, wheat, oats, barley, and dairy and packing house by-products - readily available at lower cash prices than prevail in most other states, and so our special problem is that of combining them so that eggs may be produced at the lowest cost per dozen.

SDSU Extension Circulars

The care of the corn breeding plot during the summer is a very important part and a very large part of corn breeding work. It is by properly caring for the crop that we learn ignore of the habits of the plant and learn more of giving the plants the best of care. The early cultivation of the breeding plot cannot be over emphasized. It is only by the very best of care that one can expect to be successful with a corn breeding plot, and of all care given during the year, the early cultivation is by far the …

Description Of The Corn Plant, Ralph E. Johnston, George H. Valentine

SDSU Extension Circulars

Before discussing the methods of the culture of corn we must know something of the plant itself. We must, in fact, be intimately acquainted with the plant and all its parts, their structure and something of the functions they perform. The method of growth must also be known in order to develop the desirable characters and to gradually eliminate the more undesirable characters. This circular is divided into dive divisions. Each division takes up a part of the corn plant and describes it in detail.

The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this investigation was to determine some of the factors involved in the regional adaptation of corn. The procedure has been to make a comparative study of native corn types, known to be locally adapted to various regional areas in Nebraska through long growth there. The work has been confined to the single species group - Zea mays indentata. No one variety of a common source is grown throughout the state, and therefore it has been impossible to keep within a single variety. It would appear that the data should indicate morphological and histological plant characteristics involved …

Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is apparent that many sources of error have unconsciously entered into comparative crop yield tests. The very important matter of overcoming variation in soil conditions as a source of experimental error has been quite extensively studied and reported by various investigators during the past decade. The means suggested for reducing such error have been (1) repetition of plats and (2) correction of yields according to check plats planted to a uniform variety or treatment at stated intervals. Both methods have proved of value and a combination of both may often be used advantageously. Some danger always exists of error …

Measuring Silage And Capacity Of Silos, L. W. Chase

Nebraska Agricultural Experiment Station: Historical Circulars

The condition of the corn at filling time, the rate of filling, and the length of time settling has taken place before measuring the depth of the silage, all tend to cause variations in the weight per cubic foot of the silage and in the tonnage that can be placed in a silo. The greatest variation comes when very green corn or very ripe corn is used, and because of this it is possible that a cubic foot of green silage, which may weigh fifty pounds, holds no more dry matter than a cubic foot of overripe silage which weighs …

Pork Production In Nebraska, E. A. Burnett

Nebraska Agricultural Experiment Station: Historical Circulars

This circular discusses a variety of recommendations to produce pork profitably during World War I.

Transpiration As A Factor In Crop Production, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of experiments reported in this bulletin has been to determine principles according to which water is used by crops. In many agricultural districts, water is frequently a seriously limiting factor in crop production. It has been thought that some means might be devised through a correct understanding of the principles involved, whereby economy in the use of water in farm practice could be increased. In this effort there are two chief points of attack, namely, (1) adjusting the external factors to the needs of the plant, and (2) selecting plants adapted to the conditions.

Pb1908-27 Loss From Cornstalk Disease In Custer County, Nebraska, During The Winter Of 1906-1907 (Distributed January 1908, Reprinted December 1930), F.J. Alway, A.T. Peters

University of Nebraska-Lincoln Extension: Historical Materials

"Cornstalk disease" is the name given to the cause or causes of death of cattle allowed to run in fields of standing cornstalks from which the ears have been gathered. It is probable that "many different maladies have been included under this name." In Nebraska, however, there is such a similarity in the symptoms reported by the farmers that it seems probable that the great majority of the losses attributed to cornstalk disease are really due to some common cause. As to the exact nature of this cause nothing is known. However, various theories have been advanced, and methods of …
