Evaluation of dry-weight-rank and microscopic point techniques for seasonal botanical analysis of two pasture mixtures

Creator:: Bauer, Welby
Abstract:: This study was undertaken to evaluate the dry-weight-rank and microscopic point methods for determining botanical composition on perennial ryegrass (Lolium perenne L.) - subclover (Trifolium subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) - subclover pasture mixtures throughout a grazing season. Botanical composition was determined on a monthly basis from...

Evaluation of species composition by four methods on two perennial grass pastures (Festuca arundinacae Schreb. and Lolium perenne L.) grazed lightly and heavily in western Oregon

Creator:: Pessot Zorich, Rafael
Abstract:: The present study was undertaken to evaluate the seasonal botanical composition of two grass pastures, tall fescue (Festuca arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.). Botanical composition was determined by four methods: dry-weight-rank, weight-estimate, hand separation, and the constituent differential, with cattle and sheep grazing at two intensities. The...

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...

Improving the Forage Species Selection Process through Research and Teaching Projects

Creator:: Randow, Brianna Lyn
Abstract:: Species selection is a complex process that forage producers and land managers face. Accurate tools and educational materials are needed to help make the decision process easier. Crop simulation models are one tool that could be utilized to predict yield and potential financial return of various species. Two crop simulation...
