Potato production practices for home gardens
vary in some details from commercial potato pro-
duction practices. Some superior varieties that
would not produce adequately in the field can be
raised in home gardens. Likewise, fungicides and
insecticides that would be either uneconomical or
impractical for commercial production can be used
in gardens.
Varieties The following varieties all possess exceptional
cooking quality and are well suited to home garden prodlsiction:
Early Red Varieties Late White Varieties Norland Kennebec Red La Soda Nampa (russet)
Nooksack (russet) Russet Burbank (Netted
Gem) Early White Varieties
White Rose Norgold Russet The Nooksack variety is quite dormant and
should store well under good potato storage condi- tions. For planting purposes, the Nooksack variety should be preconditioned four to six weeks to break dormancy.
You can get seed stock of these varieties from local feed and seed stores. Be sure to plant certified seed; this will help assure good production and freedom from inherent diseases. Commercial pota- toes are often treated in a way to prevent sprout- ing, thus they should be avoided for seed.
Cutting and Seed Treatment Cut seed tubers into halves or quarters, depend-
ing on their size. Each seed piece should weigh one and a half to two ounces, and each one must have at least one eye or it wifi not grow. After cutting, treat the seed pieces with Captan or a similar material to assure "healing" of the cut sur- faces and prevent rotting and disease spread. Every seed piece must be completely covered with the seed-treatment material. These materials can be

purchased at local feed stores. Be sure to follow the directions on the package.
Fertilization Central and eastern Oregon. Use 16-20-0 ferti-
lizer. It contains 16% nitrogen and 20% phosphorus. In certain areas, potash is also needed and in such cases fertilizer practices for western Oregon should be followed. Work the fertilizer into the soil at a rate of 14 pounds per 1,000 square feet. A highly satisfactory alternative method is to place one- fourth ounce of this fertilizer about 3 inches to either side and about 1 inch below the seed piece at planting time.
Western Oregon. Use a 10-16-8 fertilizer. It contains 10% nitrogen, 16% phosphorus, and 8% pot- ash. Apply the fertilizer at a rate of 17 pounds per 1,000 square feet, or one-half ounce to either side and about one inch below the seed piece.
Planting Space rows about 3 feet apart with seed pieces
about 1 foot apart in the row. Plant the seed pieces 3 inches deep as soon as possible after cutting and treating. Plantings can be made as soon as the ground warms up in the spring until as late as the end of June. The earliness of planting, as well as choice of variety, will influence the earliness of the crop. Plant potatoes intended for winter storage later than those for summer use.
Cultivation As the plants grow, "hill up" or pile soil around
their bases and about 6 inches to either side. Sun- light causes newly formed tubers to turn green, and this practice helps to keep them away from the sun. Do not completely cover the plant foliage.
The control of weeds is important. The best, easiest, and most economical method is by mechan- ical means, such as hoeing. It is only necessary to scratch beneath the surface enough to sever weed roots. Do not hoe too deeply. Cultivate after heavy rains also to keep the soil loose.

Extension work is a cooperative program of Oregon State University, the U. S. Department of Agriculture, and Oregon counties.
Irrigation If irrigation is to be practiced, begin when the
plants are about 5 inches high. Once irrigation is started, the ground should be kept damp. If the soil dries following irrigation, an increased percent- age of small, knobby tubers of inferior quality will result.
Harvesting Potatoes can be harvested and used at any time.
Immature tubers may be desirable for some cook- ing uses or for immediate table use, but they will not store for long without rotting and shriveling.
If tubers are to be stored for winter use, harvest after the vines have died down as a result of frost or the discontinuance of irrigation. At least two weeks should elapse after the vines die before starting to dig in order to permit the skins to thicken and the tubers to mature.
Storage Store tubers in a cool, dark place where there
is no danger of freezing. The skins should be well set before potatoes are stored.
Disease Control The most serious diseases of potatoes are car-
ried in the seed. These virus diseases can be pre- vented by the use of "certified seed."
Both early and late blight of potatoes occur in western Oregon. Late blight has never been ob- served in eastern Oregon, but early blight can cause losses. Both early and late blight can be con- trolled by spray or dust applications at 7 to 10-day intervals with Maneb. if only late blight is a prob- lem, it can be controlled with spray or dust appli- cations of Bordeaux mixture or tribasic copper sul- fate applications at 7 to 10-day intervals. Follow instructions on the label closely for best results.
Insect Control Fleabeetles. Control of fleabeetles is a must in
western Oregon and in certain localized areas of eastern Oregon. The presence of these beefles is indicated by small round holes in the leaves, but the damage is caused by the larvae feeding on the tubers.
Control fleabeetles by spraying or dusting with Sevin as directed on the package. Begin treatment when two-thirds of the plants have emerged from the soil and continue at 10-day to two-week inter- vals throughout the season or when damage is ob- served.
Colorado potato beetles. These beetles are sometimes a pest in central and eastern Oregon. Control them with Sevin as directed on the pack- ages.
Mites. Very small, spiderlike creatures, mites can be detected by their feeding which causes the plants to appear yellowish and dry. Webbing may be observed. Malathion usually will control mites, but in some areas they may be immune to this material.
Aphids. Important vectors of serious virus dis- eases, aphids decrease yield and quality of tubers. Control can be obtained with malathion.
