Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This is the twelfth report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 by the Nebraska Agricultural Experiment Station in cooperation with the Agricultural Research Service (ARS), U.S. Department of Agriculture, under contract number AID/ta-C-1093 with the U.S. International Development Corporation, Agency for International Development. The Nursery was designed to (1) test the adaptation and stability of winter wheat cultivars in a range of latitudes, daylengths, fertility conditions, water management regimes, and disease complexes; (2) identify superior winter cultivars to serve as recipient genotypes for high protein and high lysine genes; (3) test the degree …

Day-Degree Methods For Pest Management, Kenneth P. Pruess
Department of Entomology: Faculty Publications
Recommendations are made for reporting day-degree methods which may have practical applications. Standardized thresholds (40, 50, and 60°F, or 5, 10, and 15°C) should be used. Day-degrees may be either sine wave approximations or exact units determined by instrumentation. Methods are proposed for converting current day-degree models to standardized thresholds and, ultimately, to actual day-degrees.

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