Investigations Of Field Performance And Physiological Effects Of Metsulfuron And Metsulfuron Combinations On Field Bindweed (Convolvulus Arvensis L.), Hamid Rahimian Mashhadi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field bindweed (Convolvulus arvensis L.) is a noxious perennial weed of many fallow and cropland fields all over the world. Present control methods are not satisfactory for field bindweed. Metsulfuron, 2[[[[(4-methoxy-6-methyl-1,3,5-triazine-2-yl) amino] carbonyl] amino] sulfonyl] benzoic acid, is a new herbicide that has been shown to have activity on bindweed especially when tank mixed with other herbicides. This study was conducted to investigate the field performance and some physiological effects of metsulfuron on field bindweed.

Neither metsulfuron alone nor metsulfuron combinations gave persistent control of field bindweed. Metsulfuron usually increased the activity of other bindweed herbicides. Herbicide application to …

Weed Control Investigations On Some Important Aquatic Plants Which Impede Flow Of Western Irrigation Water, United States Department Of The Interior, Bureau Of Reclamation

Elusive Documents

During the past 50 years, the acreage of land placed under irrigation in the western United States has increased greatly to meet the growing demand for food and fiber production. To provide this water for crop production it is necessary not only for river waters to be impounded and irrigation canal distribution systems established but also for the irrigation waterways to be free of obstructing plant growths which impede the flow of water. This requires various types of weed control measures in order that originally designed carrying capacities of the waterways may be maintained. Methods involving new techniques developed mostly …

Bulletin No. 268 - Alfalfa Seed Investigations And Other Crop Varietal Studies: Millard County, Utah 1929 To 1933 (Inclusive), George Whornham

UAES Bulletins

The Delta Area, in which most of the alfalfa-seed investigations and crop studies reported in this bulletin were conducted, is located in Millard County which is in the west-central part of Utah. This area lies in the Sevier Desert, within the eastern boundary of the Great Basin in the northeastern part of the county.

Parts of the area, particularly the farming sections near the towns of Oasis, Deseret, and Hinckley, have been among the oldest and most consistent alfalfa-seed producing sections of the United States. The peak of alfalfa-seed production in Millard County was reached in 1925, when approximately 14,000,000 …

Bulletin No. 258 - Alfalfa-Seed Investigations In Utah, John W. Carlson

UAES Bulletins

For many years alfalfa-seed production problems have engaged the attention of investigators in various parts of the world. Those factors which are regarded as of greatest importance in seed-setting are general climate, current weather, air humidity, soil moisture, and insect relationships within the various alfalfa-seed districts. Some attention in research has been given to pollen fertility and ovule sterility, as well as to general flower dynamics in relation to environmental conditions. Efforts have been made to develop strains of alfalfa having pollen that is resistant to injury by moisture or having self-tripping flowers or autogamous strains of alfalfa whose flowers …

Bulletin No. 224 - Muck Soil Investigations: Progress Report, Sanpete County Experimental Farm 1927-30, Inclusive, Le Moyne Wilson, George Stewart

UAES Bulletins

The estimated area of muck or peat soil in Utah is approximately 21,000 acres. The muck occurs in many valleys of Utah. The largest areas are in the Sanpete and Utah Lake Valleys. The area in the former is estimated at 6500 acres and the Utah Valley area at 9000 acres; the other areas, all more or less significant in size, are scattered throughout the state.

Investigations reported have been confined entirely to the Sanpete area which is located near the south and bottom end of the valley and is west of the towns of Chester, Ephraim, and Manti. During …

Bulletin No. 181 - Duty-Of-Water Investigations On Coal Creek, Utah, Arthur Fife

UAES Bulletins

Coal Creek flows from the west slope of the part of the Wasatch Mountain range which is located in the southeast part of Iron County, Utah. Its drainage area is almost 100 square miles.

Seasonal and daily stream-flow fluctuations are very pronounced. During the high water of spring the flow has reached more than 600 second-feet. At the time of high water, the daily fluctuations are the greatest. During the low water season in July and August, the flow has dropped as low as 12 second-feet since 1917, when accurate records were first kept; and, from the accounts of early …

Bulletin No. 105 - Factors Influencing Evaporation And Transpiration, John A. Widtsoe

UAES Bulletins

The irrigation investigations conducted by the Utah Experiment Station, some of the results of which form this *report, were undertaken for the purpose of adding to our knowledge of the natural laws upon which the art of irrigation may be safely built. The work has had for its dirrect object the study of the mutual relations of plants, soils and water, as these relations may indicate the most economic use of water for plant production. In pursuit of the investigations it became necessary not only to follow the movement of water in soils under irrigation conditions, but to determine also …

Bulletin No. 100 - Arid Farming Investigations, W. M. Jardine

UAES Bulletins

The Utah Legislature of 1903 passed a bill providing for the investigation by the Experiment Station of dry-land farming problems in the State of Utah, and appropriating $12,500 to be expended in carrying on this work during the two years, 1903 and 1904. Six experimental dry farms were located one in each of the following counties: Iron, Juab, San Juan, Sevier, Tooele and Washington. A second appropriation of $15,500 was made by the Legislature of 1905, for the purpose of continuing, the investigations.

Bulletin No. 99 - Report On Irrigation And Drainage Investigations During 1905-1906, E. R. Morgan, W. W. Mclaughlin

UAES Bulletins

A general plan for the scientific investigation of the laws governing plant production as influenced by the application of irrigation water, was outlined in 1900 by Dr. John A. Widtsoe as Director of the Utah Experiment Station. The detailed plans were prepared by the heads of the Chemical, Agronomy and Irrigation Department, under whose cooperation the work was to be carried on. In 1903 the Office of Experiment Stations of the U. S. Department of Agriculture, by contributing funds to this work, became a party to the experiments. Since then the investigations have been under the joint supervision of the …

Bulletin No. 80 - Irrigation Investigations In 1901, John A. Widtsoe

UAES Bulletins

The fact that the ancient and, to arid countries, indispensible art of irrigation lacks a scientific basis, is the justification of the decision taken two years ago by the officers of the Utah Experiment Station, to make irrigation the central subject of their investigations.
