Rural Flies In The Urban Environment?, Gustave D. Thomas, Steven R. Skoda Feb 1993

Rural Flies In The Urban Environment?, Gustave D. Thomas, Steven R. Skoda

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Because metropolitan areas in the United States have been expanding at a dramatic rate, there has been direct competition between rural and urban interests for land. Also, market pressures often make it most profitable for meat producers to locate as close to urban centers as possible. A resultant growing interface between rural and urban centers, coupled with inadequate understanding of the people between the two centers, provides a potential for problems to develop. This book generally summarizes one area of contention - flies: few people tolerate flies in any setting anymore.

Packer Integration Into Hog Production: Current Status And Likely Impacts Of Increased Vertical Control On Hog Prices And Quantities, Azzeddine M. Azzam, Allen C. Wellman

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

In a survey conducted three years ago by the staff of Pork '88, it was found that some of the major players in the pork industry, like Smithfield foods, for example, have either integrated into hog production or have all the requirements for vertical integration in place. The move toward internalizing the exchange process in the hog/pork sector through vertical integration has raised several questions ranging from its impact on prices and quantities to its impact on individual hog producers. This report is a first step toward studying these issues. Its specific objectives are a) to provide some insights into …

Soybean Chlorosis Studies On High Ph Bottomland Soils, E. J. Penas, R. A. Wiese, R. W. Elmore, G. W. Hergert, R. S. Moomaw

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Soybean varieties are different in tolerance to lime-induced chlorosis. Field trials were conducted to evaluate variety performance on soils where chlorosis in soybeans was a known problem. Thirty-six varieties out of 177 were identified as tolerant to soil conditions that cause chlorosis. Eleven varieties of these 36 were found to have the most consistent yield performance on high pH soils. Tolerant varieties must be planted at adequate densities for best performance. A seeding rate of 13.5 seeds per foot of row, the highest seeding rate employed, did not appear to maximize yield on soils where chlorosis was severe. On some …

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble Aug 1990

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.

Commodity-Specific Effective Exchange Rates For U.S. Agriculture, Emilio Pagoulatos, Azzeddine Azzam Jan 1987

Commodity-Specific Effective Exchange Rates For U.S. Agriculture, Emilio Pagoulatos, Azzeddine Azzam

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A number of commodity-specific effective exchange rates of relevance to U.S. agriculture have been constructed. It is hoped that data presented in this study will be of use to researchers investigating the interrelationships between the dollar exchange rate and agricultural trade. An examination of the variability properties of the various agricultural trade-weighted exchange rate indices suggests that in modeling the agricultural trade-exchange rate relationship, the volatility of the exchange rate should be considered along with its level as explanatory variables.

Chemical, Physical And Mineralogical Properties Of Mitchell And Tripp Soils In The Nebraska Panhandle, G. A. Uzochukwu, D. T. Lewis Oct 1986

Chemical, Physical And Mineralogical Properties Of Mitchell And Tripp Soils In The Nebraska Panhandle, G. A. Uzochukwu, D. T. Lewis

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Mitchell and Tripp soils are some of the most important agricultural soils in the Nebraska Panhandle. Yet, they have received little attention in terms of their basic chemical, physical, and mineral properties. Management decisions can be made on a more informed basis if this kind of information is available. This study was to acquire the information, with special emphasis on mineralogical properties of the soils and their parent materials. This emphasis was given because it is known that other soils in the region contain volcanic ash in measurable amounts. The presence of volcanic ash in soils has been associated with …

Evaluation Of Crested Wheatgrass Introductions For Forage Yield And Quality, K. P. Vogel, P. E. Reece, J. F. S. Lamb

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Crested wheatgrass, Agropyron cristatum and A. desertorum, are among the most important cool-season forage grasses in the United States and Canada, particularly for reseeding arid range sites. Further improvement in this grass by breeding depends on identifying sources of genetic variability for forage yield and quality. Foreign introductions are an obvious source of genetic variation since crested wheatgrasses are introduced species. In this study 38 accessions (PI lines) and 8 Nebraska experimental lines were evaluated for forage quality as measured by in vitro dry matter digestibility (IVDMD) and protein content and for forage yield. The cultivars 'Ruff' and 'Nordan' …

Price, Yield And Net Income Variability For Selected Field Crops And Counties In Nebraska, Boris E. Bravo-Ureta, Glenn A. Helmers

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The primary objective of this study was to establish an empirical estimate of the riskiness of various crops in different regions of Nebraska. For this purpose the variate difference method was used to estimate random variability indexes of prices, yields, and net returns for six Nebraska crops (wheat, soybeans, alfalfa, oats, grain sorghum, corn). The period of analysis included 1957-1976 and one county in each of the eight crop reporting districts was analyzed. Where relevant, both dryland and irrigated alternatives were examined. Most business decision-makers accept more risk only under the conditions that the probability of higher returns accompany risky …

Evaluation Of Bromegrass Introductions For Forage Yield And Quality, Kenneth P. Vogel

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Smooth bromegrass (Bromus inermis Leyss.) is one of the most important cool-season forage grasses in the United States and Canada. Further improvement in this grass by breeding depends on identifying sources of genetic variability for forage yield and quality. Since smooth bromegrass is an introduced species, foreign introductions are an obvious source of genetic variability. This study evaluated 49 smooth bromegrass introductions for forage yield and quality as measured by in vitro dry matter digestibility (IVDMD) and protein content and compared them with the cultivar 'Lincoln'. Evaluated in a separate study and reported here were eight meadow bromegrass ( …

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Three tests in southwestern Nebraska during 1971 and 1972 evaluated insecticides against the army cutworm. Adult alfalfa weevils did not damage new second growth alfalfa in a small plot study during a 3-year period (1973-1975) at Gothenburg, NE. However, excellent control of larval alfalfa weevils was obtained. These results indicated a need to establish economic threshold levels for the alfalfa weevil in Nebraska to prevent unnecessary use of insecticides. Four tests to control the alfalfa weevil with registered insecticides verified the efficacy of these materials under Nebraska conditions. A series of tests conducted during 1975 at the Mead Field Laboratory …

Economic Implications Of Alternative Dry-Bulk Fertilizer Supply Systems: A South-Central Nebraska Case Study, Mary Berglund, Dale G. Anderson Nov 1979

Economic Implications Of Alternative Dry-Bulk Fertilizer Supply Systems: A South-Central Nebraska Case Study, Mary Berglund, Dale G. Anderson

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This study analyzed the economic implications of alternative patterns of rail service for a case-study area in south-central Nebraska. Special attention was given to effects of branchline abandonments on the delivery system for dry-bulk fertilizer. The study was an extension of an earlier Nebraska track abandonment study which focused only on grain traffic. The purpose of the latest study was to establish the effect of including dry-bulk fertilizer, the major commodity moving into the area by rail, on the earlier results. The addition of fertilizer to the analysis did not appreciably change the outcome of the earlier grain-oriented study.
