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.
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.
Forage production is of primary importance to Oregon’s livestock enterprises and agricultural economy. The forage is either grazed or conserved.
Conserved forage is needed to feed livestock in times of little forage growth—a key cost of livestock production. Extending the grazing season reduces the cost and time involved in feeding...
