Fluometuron And 2,4,5-T Residues In Soil, Sediment, Runoff Water, And Percolation Water, Glenn Gray Davis Dec 1973

Fluometuron And 2,4,5-T Residues In Soil, Sediment, Runoff Water, And Percolation Water, Glenn Gray Davis

Doctoral Dissertations

The rates of disappearance of 1,1-dimethyl-3-(a, a, a-trifluoro-m-toly1) urea (fluometuron) and the propylene glycol butyl either esters and a triethylamine salt of (2, 4, 5-trichlorophenoxy) acetic acid (2, 4, 5-T) from the application site in field plots and lysimeters were determined. Residual herbicide concentrations were estimated for field plot soil, runoff water collected in the plots after rainfall, and permanently impounded drainage water from the plots. Bioassays, spectrophotometry, and gas-liquid chromatography were utilized to detect residual concentrations of the three compounds. Linear and multicurvilinear equations were developed from known concentrations of the herbicide for predictions of residue amounts …

Morphological And Physiological Factors Related To Yield Of Alfalfa, A. L. Foutz, Wallace Wilhelm, A. K. Dobrenz Nov 1973

Morphological And Physiological Factors Related To Yield Of Alfalfa, A. L. Foutz, Wallace Wilhelm, A. K. Dobrenz

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Several morphological and physiological factors were measured on clones of alfalfa (Medicago sativa L. ‘Mesa- Sirsa’) which displayed a wide range in SLW, leaflet weight and leaflet area. Apparent photosynthesis, dark respiration and post-illumination burst expressed as mg C02 dm-2hr-1 were not related to yield. However, when the rate of each factor was expressed on a whole plant basis (rate x leaf area per plant) , significant relationships were found with yield. Correlation coefficients between total apparent photosynthesis, total dark respiration, total post-illumination C02 burst and yield were r = .71*, r = .77* …

Results Of The Third International Winter Wheat Performance Nursery, J. E. Stroike, V. A. Johnson, J. W. Schmidt, P. J. Mattern, K. D. Wilhelmi Nov 1973

Results Of The Third International Winter Wheat Performance Nursery, J. E. Stroike, V. A. Johnson, J. W. Schmidt, P. J. Mattern, K. D. Wilhelmi

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 by the Nebraska Agricultural Experiment Station and the Agricultural Research Service, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. The nursery was designed to (1) test the adaptation of winter wheat varieties in a range of latitudes, daylengths, fertility conditions, water management, and disease complexes; (2) identify superior winter varieties to serve as recipient genotypes for high protein and high lysine genes, and (3) test the degree of expression and stability of the …

Results Of Systematic Analyses For Protein And Lysine Composition Of Common Wheats (Triticum Aestivum L.) In The Usda World Collection, K. P. Vogel, V. A. Johnson, P. J. Mattern Nov 1973

Results Of Systematic Analyses For Protein And Lysine Composition Of Common Wheats (Triticum Aestivum L.) In The Usda World Collection, K. P. Vogel, V. A. Johnson, P. J. Mattern

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Protein and lysine contents of 12,613 common wheats of the USDA World Wheat Collection were determined in order to identify wheats that may be sources of genes for high protein and high lysine. Results indicate that significant genetic differences in protein and lysine content probably exist among world collection common wheats. Selection criteria have been developed for further evaluation of World Collection lines high in protein and lysine content.
