The Identification Of The More Important Prairie Hay Grasses Of Nebraska By Their Vegetative Characters, F. D. Keim, G. W. Beadle, A. L. Frolik
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 Vitamin A And The Vitamin E Content Of Field-Cured And Artificially Cured Alfalfa Hay, I. L. Hathaway, H. P. Davis, R. R. Graves
The Vitamin A And The Vitamin E Content Of Field-Cured And Artificially Cured Alfalfa Hay, I. L. Hathaway, H. P. Davis, R. R. Graves
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A comparative study of the vitamin A content of field-cured and artificially cured alfalfa was made by comparing the growth produced by 124 rats receiving alfalfa hay as their source of vitamin A. From the results of this study, in which the experiments were duplicated, it is concluded that under the conditions of these experiments the artificially cured alfalfa was twice as potent in vitamin A as was the field-cured alfalfa. The comparative study of the vitamin E content of these hays was made by comparing the number of litters produced by groups of female rats which received graded quantities …
The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder
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 …
Tuber Development In Triumph Potatoes As Influenced By Time Of Planting On Dry Land In Northwestern Nebraska, H. O. Werner
Tuber Development In Triumph Potatoes As Influenced By Time Of Planting On Dry Land In Northwestern Nebraska, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Triumph potatoes were planted on four different dates during six years in order to determine the best planting date on dry land in northwestern Nebraska, where this variety is grown primarily for seed. Features considered in comparing the merits of these planting dates were: stand of plants; vine growth; disease prevalence; time of plant maturity; number, size, and shape of tubers; cracking at harvest time; prevalence and severity of common scab; total yields and yields of various grades of potatoes from various harvesting dates; weight loss in storage; and duration of the dormant period. The experimental aspects dealing with the …
Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle
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 …
