Spring irrigation management of tall fescue (Festuca arundinacea Schreb.) seed crops

Creator:

Orthel, Krista D.

Abstract:

Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...

Paclobutrazol and nutrient treatment effects on ovation perennial ryegrass

Creator:

Turner, J. Kevin

Abstract:

Rapid tiller and root production can improve seedling survival and benefit stand establishment of perennial ryegrass (Lolium perenne L.) in commercial seed fields. Environmental conditions after establishment and inherent morphological factors combine to reduce the commercially harvested yield below the theoretical potential yield. These studies were conducted to determine if...

Possible association of grain protein content, harvest index and biological yield in winter wheat populations

Creator:

Costa, Jose Maria

Abstract:

A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding...

The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

Creator:

Maxwell, Bruce D.

Abstract:

Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...
