Management Of Four Alfalfa Varieties To Control Damage From Potato Leafhoppers, W. R. Kehr, R. L. Ogden, J. D. Kindler
Management Of Four Alfalfa Varieties To Control Damage From Potato Leafhoppers, W. R. Kehr, R. L. Ogden, J. D. Kindler
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The main purpose of this study was to obtain information on forage yield and quality of four alfalfa (Medicago sativa L.) varieties that differed in level of resistance to potato leafhopper (Empoasca fabae Harris) yellowing, when cut at three stages of growth in the second and third cuttings in field plots, with and without insecticide application. The stages of growth were bud, 1/10, and full bloom. Other purposes included study of the same varieties in field cages manually infested at 20, 40, and 60 adult leafhoppers/square yard, and in supplemental cuttings of field plots under high natural infestation …
Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern
Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The protein and lysine content of wheat can be altered by breeding only if genetic variability exists for these traits. Lysine is a nutritionally limiting amino acid in wheat protein. Protein and lysine analyses of the common wheats of the USDA World Wheat Collection indicated that variability does exist for these traits. Some of the variability for protein and lysine among wheats of the World Collection may not be genetic in origin, because all the 12,000 wheats analyzed were not grown in the same environment. The purpose of this study was to reevaluate selected lines from the World Wheat Collection …
An Economic Information Program For The U.S. Beef And Pork Sectors, N. A. Aulaqi, J. B. Hassler
An Economic Information Program For The U.S. Beef And Pork Sectors, N. A. Aulaqi, J. B. Hassler
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Major objectives of the study were: first, to review present public data programs and to indicate areas of inefficient performance in the production and marketing of beef and pork that still exist under the present data system; second, to simulate an operational information service program for the beef and pork sectors based on programmed solutions for industry allocations and activities; and third, to outline possible implementation procedures for the information service programs and to indicate the role of each of the participants in making it successful.
Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein
Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.
Bionomics Of Insects Associated With Corn In The Nebraska Sandhills, J. L. Wedberg, J. B. Campbell, T. J. Helms
Bionomics Of Insects Associated With Corn In The Nebraska Sandhills, J. L. Wedberg, J. B. Campbell, T. J. Helms
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Investigations were conducted in the Nebraska Sandhills to determine the impact of transition from grassland to irrigated corn on selected insect species, to identify indigenous species that may be economically important to corn production, and to provide a point of reference for future development of pest management programs for irrigated corn.
Leaf Freckles And Wilt Of Corn Incited By Corynebacterium Nebraskense Schuster, Hoff, Mandel, Lazar, 1972, M. L. Schuster
Leaf Freckles And Wilt Of Corn Incited By Corynebacterium Nebraskense Schuster, Hoff, Mandel, Lazar, 1972, M. L. Schuster
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The new bacterial disease Leaf Freckles and Wilt (LFW) of corn (Zea mays L.) was first observed in 1969 on two farms in southcentral Nebraska. Since then it has spread to other areas in the state. LFW is a serious disease on farms in six Nebraska counties (Clay, Custer, Dawson, Furnas, Hall and Phelps) and has been found in isolated cases in at least 28 other counties. In 1971 LFW was found in a seedcorn field in western Iowa, in 1973 in two Kansas counties, and in 1974 in South Dakota and Colorado. Because of its explosive nature, several …
A Rate/Cost Analysis Of Nebraska Meat Trucking Activities With Livestock Trucking Cost Comparisons, Dale G. Anderson, Wayne W. Budt
A Rate/Cost Analysis Of Nebraska Meat Trucking Activities With Livestock Trucking Cost Comparisons, Dale G. Anderson, Wayne W. Budt
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This study was designed to measure costs of long-distance shipment of meat by motor carrier. Costs were compared with published rates for meat shipments by truck, rail and trailer-on-flatcar (TOFC). Finally, meat trucking costs were compared with costs of trucking meat-equivalent amounts of livestock. Results of the study provide a partial basis for evaluating the economic merits of expanded livestock production activities in grain-surplus Great Plains locations. Such an expansion might aid in the economic development of the region and ease the chronic problem of rail freight-car supply. Proposals ranging from extension of present regulation to cover livestock trucking to …

The research works discussed in this review were selected to provide a cross section of the phenomenon of survival of plant pathogenic bacteria.
Growth Potential Of Sandhills Ranches Through Irrigation, R. D. Carver, G. A. Helmers
Growth Potential Of Sandhills Ranches Through Irrigation, R. D. Carver, G. A. Helmers
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The purpose of this study was to compare extensive and intensive growth strategies of a typical Nebraska Sandhills ranch in a dynamic and uncertain environment. Study objectives were to: (1) Analyze growth of an average ranch firm of 450 animal units as it grows to 600-900 animal units. (2) Study the effects of an uncertain environment on the long-run growth opportunities of a ranch firm. (3) Compare extensive and intensive growth of a ranch firm.
