Field and laboratory tests were carried out to investigate the
survival of the root-nodule bacterium, Rhizobium trifolii, when
inoculated onto seeds of the pasture legume subterranean clover,
(Trifolium subterraneum L.), in order to improve the nodulation
and establishment of this plant in acid soils.
Field experiments were carried out in...
A field study was conducted in the Willamette Valley near
Corvallis, Oregon, to determine the influence of seedling rate,
drill row spacing, grass association, and variety on the yield
of dry matter and quality (crude protein content and leafiness)
of alfalfa. Treatments included seeding rates of 7.5, 10, 15 and...
A field experiment was conducted to study the influence of cutting
treatments on the yield and quality of non-irrigated alfalfa in
western Oregon.
Spring clipping treatments included (1) not clipped, (2) clipped
when 6 inches high and (3) clipped when 12 inches high. The hay harvest
criteria were (1) near...
Field, greenhouse, growth chamber and laboratory experiments
evaluated factors affecting establishment, survival and production
of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago
sativa L.)
Field studies investigated the effects of a barley companion
crop, seedling year harvest management and nitrogen and phosphorus
fertilization upon stands, survival and subsequent production...
The winter and summer growth of varieties of tall fescue
(Festuca arundinacea Schreb.) that had originated from the Mediterranean region (Oregon 1000 and Tunisia) and northern Europe (Alta)
were studied outdoors in the Mediterranean climate of western Oregon,
and in greenhouses and controlled environment chambers. Treatments
of temperature, photoperiod and...
Field studies to determine appropriate cutting management
regimes consistent with yield, quality, and persistence
of stand were conducted on several alfalfa varieties in the
Columbia Basin region of Oregon.
Two groups of treatments, including consecutive cuts at
the same stage of maturity and cuts made at varying maturities,
were imposed...
