Stem Anatomy Of Twelve Forbs Of The Family Compositae Growing Near Hays, Kansas, Cheng Lin
Stem Anatomy Of Twelve Forbs Of The Family Compositae Growing Near Hays, Kansas, Cheng Lin
Master's Theses
The importance of forbs to the livestock diet seems to come from their high percentage of calcium and phosphorus (Runyon, 1947). Furthermore, they also contain a higher amount of moisture (Savage and Heller, 1947) which makes them more succulent and therefore more palatable than the grasses during drought. This condition of greater succulence is due in part at least to _the more deeply penetrating roots of the forbs (Albertson, 1937). Observations also have indicated the possibility of a considerable amount of latex, oils and resins in the green forb plants. Because of the importance of these plants it was thought …
Effects On Different Intensities Of Utilization Upon The Underground Parts Of Short Grasses In West Central Kansas, Farrel Branson
Effects On Different Intensities Of Utilization Upon The Underground Parts Of Short Grasses In West Central Kansas, Farrel Branson
Master's Theses
Work on root systems of forage plants has indicated that a knowledge of root relationships is fully as important in determining the actual conditions of ranges or pastures as is knowledge of the effects of grazing upon aboveground portions of plants. This is especially true in arid or semiarid regions since plants of these areas are frequently subjected to long periods of drought, high temperatures, and high wind velocities. Some xeric plants have a thickened cuticular layer, stomates that open only at night, and other mechanisms that prevent loss of water that is absorbed by the roots. However, in plants …
Pastures Of Western Kansas In Relation To Intensity Of Utilization In Past Years, Gerald W. Tomanek
Pastures Of Western Kansas In Relation To Intensity Of Utilization In Past Years, Gerald W. Tomanek
Master's Theses
Short grass pastures vary in their ability to produce forage for livestock consumption. One of the reasons for this difference is a variation in the degree of utilization in past years. Forage production of short grass ranges has been reduced to about one-half after only a few decades of improper grazing; therefore the problem of proper utilization is becoming more important every year (Forest Service, 1936). When the settlers first came to western Kansas they found an almost complete cover of native vegetation and during the first few years only a small portion of the range land was cultivated. With …
Bio-Ecology On A Mixed Prairie Near Hays, Kansas, H. Leo Brown
Bio-Ecology On A Mixed Prairie Near Hays, Kansas, H. Leo Brown
Master's Theses
A survey of the activity of wild animals in connection with range conditions and range management is greatly needed in western Kansas. To have a well-managed range one should have an understanding of the ecological factors which benefit or deplete the native vegetation that is essential for production of livestock. The impact of grazing, and the effect of changes in edaphic and atmospheric environment on the prairie have further emphasized the importance of a cover of grass in preventing erosion.
The Utilization Of Grasses And Forbs In Relation To The Intensity Of Grazing In The Mixed Prairie Near Hays, Kansas, Noel Runyon
The Utilization Of Grasses And Forbs In Relation To The Intensity Of Grazing In The Mixed Prairie Near Hays, Kansas, Noel Runyon
Master's Theses
The principal occupation of the inhabitants in the Great Plains Region is livestock farming. The problems confronting the farmers and ranchers of this large area are many and varied. Not the least of these problems is the one of a proper stocking rate for the various types of ranges in order to secure a maximum production with the least in capital outlay and range deterioration. Another problem that has presented itself in recent years is the one of revegetating thousands of acres of marginal and semi-marginal land so that mother nature may again heal the marks of erosion and bring …
The Life History Of Side-Oats Grama Grass And Variations In Its Growth At Hays, Kansas, When Grown From Seed Produced In Different Parts Of The Great Plains Region, Harold Hopkins
Master's Theses
This study, which covered a period of two years, was originated in order to learn more of the merits and faults of side-oats grama grass as a revegetation and soil conservation plant in the Great Plains Region. It was suggested by the fact that there is a definite need for more knowledge about the native grasses which are potential revegetation plants of the Great Plains. An attempt was made to find as many growth habits of the species as possible, and a comparison was made in the growth, development, and forage production of plants grown from seed produced in different …
The Effect Of Clipping And Weed Competition Upon The Spread Of Pasture Grass Seedlings, Cecil L. Hase
The Effect Of Clipping And Weed Competition Upon The Spread Of Pasture Grass Seedlings, Cecil L. Hase
Master's Theses
The drought of the last seven years with its disastrous dust storms has damaged vast areas of the native prairie as well as much of the cultivated land. Deficient rainfall has caused crop failures over large areas, leaving the fields without a protective covering. Due to these conditions, wind erosion started the dry, loose soil to drifting. Large amounts of the soil settled on the grassland and destroyed much of the native plant cover. Where t e native vegetation was weakened or destroyed, the soil was invaded by such weedy annuals as lambsquarter (Chenopodium sp. ) , Russian thistle (Salsola …
An Analysis Of Seed Production Of Native Kansas Grasses During The Drought Of 1939, Lester R. Branson
An Analysis Of Seed Production Of Native Kansas Grasses During The Drought Of 1939, Lester R. Branson
Master's Theses
The present interest in the control of soil erosion and the stabilization of agriculture has initiated a great amount of research to find suitable grasses and methods for restoring grass production. The results of these investigations have shown that the native climax grasses are best suited for reseeding in arid and semi-arid regions
The Life History And Habits Of Buffalo Grass, John J. Webb
The Life History And Habits Of Buffalo Grass, John J. Webb
Master's Theses
Buffalo grass (Buchloe dactyloides) is a dioecious, stoloniferous perennial which, with Blue Grama grass (Bouteloua gracilis), forms the short grass faciation of the Great Plains. Its range extends from Saskatchewan to Mexico in the plains area. It is exceedingly valuable as forage, both during the growing season and winter, since cured grass is relished by livestock. Its stoloniferous habits make it an aggressive plant, and give it great soil-biding properties. This species of grass has vast possibilities in revegetation practices. A study of its life-history should be of benefit to conservationists as well as to agrostologists and taxonomists. There is …
A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel
A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel
Master's Theses
During the past 7 years the Great Plains Region, with its "dust bowl", has been the scene of unparalleled activity in the fields of range management and erosion control. The people of this short grass area are extremely conscious of the need for a sound, practical program of conservation that will revegetate the wasted pasture and cultivated land, which will aid materially in preserving the eroding soil. Many problems have arisen as the program of conserving the soil and the vegetation has progressed.
