Legume plants with no nodules or with nodules containing ineffective bacteria are common causes of low production or complete failures of alfalfa and clover plantings in Oregon. These failures result in the loss of the stand plus the investment in fertilizer and seed used to make the planting. In many...

Alfalfa is an important hay crop which is grown on more than 10,000 acres in Jackson, Josephine, and Douglas counties of southern Oregon. Its estimated crop value is more than four million dollars per year. Many varieties of alfalfa are available for planting in the area. Sixty-eight varieties and experimental...

Between 1965 and 1975, four alfalfa variety test trials, which included 38 different varieties, were conducted at Redmond and Alfalfa by the Central Oregon Experiment Station. Two trials were completed and two are continuing. Hay yields averaged 6.79 and 5.39 tons per acre per year in the completed trials at...

Alfalfa is capable of producing high yields of forage when grown on deep, well-drained soils. Good management practices are essential if optimum fertilizer responses are to be realized. These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper inoculation...

New grading standards for hay have been proposed by the American
Forage and Grassland Council and the Federal Grain Inspection Service.
This publication traces the development of these standards, describes new
terminology, and reports on research conducted at Oregon State University
to evaluate these new standards.
Alfalfa hay samples obtained...
Alfalfa is an extremely important crop in the agricultural economy of Central Oregon. Some of the alfalfa is fed in livestock operations on the farms where it is produced, but most of it is sold as baled hay for use in other parts of the state and region.
Annual yields...
Alfalfa hay yields in Central Oregon are only about one-half of their potential level. Annual yields of 4 to 5 tons per acre have been considered to be very good, but if the best known establishment and management practices are conscientiously applied, much higher yields are possible. Studies done at...

Increased seeding rates (7.5, 10, 15.20 pounds per acre) and closer row spacing (12, 6 and 3 inches between rows) resulted in an increased stand of alfalfa during the early years of production. Yield of DuPuits alfalfa was not increased with the additional plants in stand. Vernal alfalfa showed a...

Alfalfa will out-yield other hay crops on deep, well-drained sot*in southern
Oregon. Irrigation is necessary for top yields, though good yietdcilpf either hay or seed can be expected without irrigation on deep soils with good moistureholding capacity. In addition to an adequate fertilizer program, these points are important for successful...

Fifteen species of Noctuidae (Lepidoptera) were collected in alfalfa and
peppermint in western Oregon. Seven of these species were hosts for the braconid
parasitoid Meteorus communis. The most frequently parasitized (percent) species were
Agrotis ipsilon (35.3), Dargida procincta (15.0), and Peridroma saucia (6.9). Other
species parasitized were Autographa californica (3.8)...
