Can I plant American Wonder potatoes for the first crop, and let enough of them mature to use for seed for the second crop, to be planted the first or middle of July? It is possible to use potatoes grown the same year as seed for the later crop, providing you let the potatoes mature first by the complete dying down of the vines, and second by digging the potatoes allow them to lie in the open air, with some protection against sun-burning, until the potatoes become somewhat greenish. If this is the case the eyes will develop and seed will grow, while without such treatment you might be disappointed in their behavior. Of course, the question still remains whether it would be desirable to do this or to plant some later variety earlier in the season when the growing conditions would be better. Potato Growing. In what locality are the best early potatoes grown in California? Can they be raised on wheat lands without irrigation as an early crop? Early potatoes are grown in regions of light frosts in all parts of the State - around the bay of San Francisco, on the mesas in southern California, and to some extent at slight elevations in the central part of the State. The potato endures some frost, but one has, for an early crop, to guard against the locations subject to hard freezing. Most of our potatoes are grown without irrigation because, on uplands, winter temperatures favor their growing during the rainy season. The middle-season and late potatoes are grown on moist lowlands where irrigation is not necessary. In proper situations, much of the land which is used for potatoes has at some time produced wheat or barley, corn or sorghum, and other field crops. Potatoes After Alfalfa. I have been a successful potato grower in Ohio. I have the best alfalfa soil and it is now in its fourth year of productiveness in that crop. I would like to grow potatoes in a small way. Proceed just as you would at the East in getting potatoes upon a red clover sod. Turn under the alfalfa deeply now if the soil will work well, and roll your sandy soil. You must use a sharp plow to cut and cover well. If there is moisture enough the alfalfa, plowed under in the fall, ought to be decayed by February, when you could plant potatoes safely, probably, unless your situation is very frosty. If you plant early you ought to get the crop through without irrigation if you cultivate well and keep the land flat. Flat or Hill Culture for Potatoes. Is it better to hill potatoes or not? During the dry time of the year potatoes should be grown with flat cultivation, except as it may be necessary to furrow out between the rows for the application of irrigation water. Potatoes grown during the rainy season in places where there is liable to be too much water, can often be hilled to advantage, but dry-season cultivation of practically everything should be as flat as possible to retain moisture near the surface for the development of shallow-rooting plants.
