The seasonal yield, quality, and utilization of Trifolium subterraneum in mixture with festuca arundinacea and Lolium perenne in western Oregon

Creator:: Sanders, Kenneth D. (Kenneth Dwayne), 1940-
Abstract:: In 1959, a large scale grazing study in western Oregon was initiated to compare the value of perennial ryegrass (Lolium perenne L.) with subclover (Trifolium subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) with subclover, and to evaluate common use grazing on them. The present investigation was undertaken to determine...

Enhanced efficiency nitrogen fertilizers for nitrogen management in the Columbia Basin, Oregon

Creator:: Holcomb, Jess Charles
Abstract:: Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching, and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...

Influence of nitrogen fertilization management on the bread making quality of different wheat genotypes

Creator:: Derényi, Marina Castro
Abstract:: Breadmaking quality is an important criterion in breeding and development of hard wheat (Triticum aestivum L.) cultivars. Improvements in N management are needed to produce superior quality grain and satisfy market demands for protein content. Field experiments with three hard red and two hard white spring wheat cultivars were conducted...

Effects of residual and applied nitrogen on Nugaines wheat

Creator:: Laopirojana, Pojanee
Abstract:: A study was made to evaluate the effect of different rates of N fertilization on Nugaines wheat. The variable N treatments provided different N regimes as a basis for evaluating potential diagnostic tests for assessing the N status of the wheat plant. The crop was grown in Lane county during...

Influence of leachates from western juniper slash on three native grasses

Creator:: Ramsey, Katherine J.
Abstract:: Paired 30-day trials were conducted to evaluate Agropyron spicatum germination when treated with two concentrations of throughfall leachates from western juniper slash in two stages of decomposition. Data from a second pair of 49-day greenhouse trials were analyzed to evaluate emergence and growth of Aqropyron spicatum, Oryzopsis hymenoides, and Poa...
