Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, Theodore A. Kiesselbach
Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, Theodore A. Kiesselbach
University of Nebraska-Lincoln Extension: Historical Materials
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 …

Management Of Irrigated Land: Report Of The Scottsbluff Experiment Substation, Mitchell, Nebraska, Fritz Knorr
Management Of Irrigated Land: Report Of The Scottsbluff Experiment Substation, Mitchell, Nebraska, Fritz Knorr
University of Nebraska-Lincoln Extension: Historical Materials
SUMMARY.
Seepage may be prevented to some extent by employing proper methods of irrigation. Overirrigation may have a tendency to water-log the soil.
A small head of water, properly used, will irrigate more land and do better work than a large head gone over the land hurriedly.
The distance of irrigation ditches should be such that the water may travel between the ditches in about two hours.
If land can be irrigated in the fall with the same care that crops are irrigated in the summer, there is an advantage to fall irrigation. If water cannot be properly cared for …
Corn Silage And Alfalfa Hay For Beef Production, Ralph K. Bliss, C. B. Lee
Corn Silage And Alfalfa Hay For Beef Production, Ralph K. Bliss, C. B. Lee
University of Nebraska-Lincoln Extension: Historical Materials
SUMMARY.
1. A ration of corn and alfalfa hay produced the cheapest gains of any ration used. Furthermore, the steers fed corn and alfalfa hay made as rapid gains as did the steers on any other ration.
2. Had the alfalfa hay used in the first experiment cost $20 per ton, the average profit on the three lots receiving alfalfa would have been 15 per cent greater than the profit on the best one of the three lots not receiving alfalfa.
3. Cold pressed cottonseed cake did not give as good results, as regards either rate of gain or economy …

Raising The Dairy Calf, E. G. Woodward
Raising The Dairy Calf, E. G. Woodward
University of Nebraska-Lincoln Extension: Historical Materials
There are in Nebraska more than 600,000 dairy cows. The average period of usefulness of the dairy caw is not more than eight years. This means that to maintain the dairy herds of Nebraska at their present size between 70,000 and 80,000 heifer calves must be raised each year. To mate these cows properly with dairy bred bulls will require the rearing of about 8,000 bulls yearly. Aside from the necessity of maintaining the herds at their present size, the importance of calf raising to the Nebraska dairyman lies in the fact that this is the surest and most satisfactory …

Soy Beans And Cowpeas, Theodore A. Kiesselbach
Soy Beans And Cowpeas, Theodore A. Kiesselbach
University of Nebraska-Lincoln Extension: Historical Materials
In recent years considerable interest has been manifest in Nebraska concerning soy beans and cowpeas; and numerous inquiries regarding them have come to the Experiment Station. The cowpea is regarded as a profitable crop chiefly in the cotton states, but has some importance as far north as Missouri, Illinois, Indiana, and Ohio. On the other hand, the soy bean is adapted primarily to the Northern States between the regions best suited for cowpeas in the South and Canada field peas in the North. The Central States in which they are most commonly grown are Illinois, Indiana, Ohio, and Michigan, and …

University of Nebraska-Lincoln Extension: Historical Materials
The true grasses belong to the one family Poaceae, often called Gramineae, and constitute a very well defined natural group of plants. This family comprises upward of 3,000 species distributed among almost 300 genera. From the economic point of view the family is of supreme importance thru the fact that here belong the cereals, which supply a large part of the food of man, and the forage grasses which are so important as feed for our domesticated animals.
The genera and species are for the most part separated by artificial characters—a fact which renders their study and identification extremely difficult …

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 …
