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...
An adequate soil fertility program will pay big dividends in the production of field corn, providing the recommended variety is seeded, weeds and other pests are controlled, and an adequate moisture level is maintained. Corn effectively uses the nitrogen built up by alfalfa or clover and the nutrients supplied by...
Peppermint was introduced into central Oregon in 1955. (The acreage devoted to this crop has been steadily expanding.) Additional experiments are needed on this crop to determine the effects of fertilizer placement and time of application.
Irrigated pastures are usually composed of a mixture of improved grasses and legumes. Maintaining a proper balance between grasses and legumes is essential to obtain maximum production.
Management is the key to production from irrigated pastures. Proper management of livestock and irrigation water can materially increase pasture production.
Over 50 fertilizer experiments on winter wheat have been conducted in Baker, Union, and Wallowa counties since 1957. Results of these experiments indicate that nitrogen and moisture are the main factors limiting wheat production in this area.
Fertilizer experiments have been conducted in northeastern Oregon on fine fescue since 1958. The following recommendations are based on these experiments and on observations of farm fields.
Irrigated pastures in western Oregon usually consist of Ladino or New Zealand white clover and Alta fescue, perennial ryegrass, orchardgrass, or meadow foxtail. These recommendations are intended for improved pastures with a good stand of clover and improved perennial grasses. Fertilizer seldom pays on weeds or weedy grasses.
Improved nonirrigated pastures consist of subterranean clover) New Zealand white clover or lotus major (big trefoil). These legumes are generally planted with perennial or H-1 ryegrass, alta fescue, orchardgrass, or meadow foxtail.
Fertilizing weeds and weedy grasses (bent, velvet, and June grass) seldom pays.
