Alfalfa Insect Management Studies 1971-77, G. R. Manglitz, W. R. Kehr, D. L. Keith, J. M. Mueke, J. B. Campbell, R. L. Ogden, T. P. Miller

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 …

Influence Of Fertilizer Nitrogen And Sulfur On Production Of Malting Barley, G. W. Rehm, R. S. Moomaw

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Studies in north-central Nebraska from 1975 through 1977: 1. Evaluated the malting barley production potential of the irrigated sandy soils of the region. 2. Measured the effect of application of N and S on yield and quality of barley grown for malting purposes. 3. Investigated the ability of N analysis of barley in the vegetative stage to predict protein content of grain at harvest. Data gathered lead to the following conclusions: 1. The potential for production of malting barley on irrigated sandy soils of north-central Nebraska is limited. 2. Yields increased with the application of fertilizer N throughout the study …

Results Of The Second High Protein-High Lysine Wheat Observation Nursery Grown In 1976, S. L. Kuhr, K. D. Wilhelmi, V. A. Johnson, P. J. Mattern

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the second report of results from a high protein-high lysine (HP-HL) observation nursery organized in 1974 by the Nebraska Agricultural Experiment Station and the Science and Education Administration, U. S. Department of Agriculture, under a contract with the Agency for International Development, U. S. Department of State. Primary objectives of this nursery are to: (1) Systematically provide breeders and cooperators with superior genetic germplasm for elevated levels of protein and/or lysine. (2) Test the degree of expression of the high protein and high lysine traits in a diverse array of environments. Funding from USAID has permitted the Nebraska …
