The Identification Of The More Important Prairie Hay Grasses Of Nebraska By Their Vegetative Characters, F. D. Keim, G. W. Beadle, A. L. Frolik Dec 1932

The Identification Of The More Important Prairie Hay Grasses Of Nebraska By Their Vegetative Characters, F. D. Keim, G. W. Beadle, A. L. Frolik

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

It is convenient and sometimes necessary to identify the grasses in their vegetative stage of growth. This is especially desirable in a study of the vegetation of native hay meadows and permanent pastures. This key is prepared as a guide in the identification of the more important prairie hay grasses of Nebraska. The meadows are often harvested before the floral parts of many of the grasses appear. If it is desired, therefore, to study the botanical composition of the native meadows, it becomes necessary to rely on identification of many of the grasses by means of vegetative characters.


The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder Oct 1932

The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Alfalfa wilt was first discovered in 1924 in southern Wisconsin and northern Illinois. The causal organism, Aplanobacter insidiosum, was later described by McCulloch. Since that time wilt has been reported from most of the alfalfa-growing sections of the United States and in some states it has been responsible for a rapid decrease in the acreage of alfalfa. During the past three years a number of investigators have found that certain alfalfas are somewhat resistant to wilt, whereas others are very susceptible. At the Nebraska station the results to date indicate that all common and most variegated alfalfas are very …


Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle Mar 1932

Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

During five years, 1924-1928, Nebraska ranked first among the states in the production of prairie hay. Approximately 2,500,000 tons were grown annually during this period. In acreage utilized, wild hay ranked third among the field crops of Nebraska. As a forage crop in the state, prairie hay ranked first in acreage, but second to alfalfa in production. The purpose of this bulletin is to report studies made of the botanical structure and yields of the native hay meadows during a period of four years, 1926-1929, in the most prominent prairie hay producing section of the state. Four counties in this …
