Excerpt from Reconnoissance Soil Survey of the Lower San Joaquin Valley, California Sunflowers are grown in the area, chiefly near Manteca. The acreage varies widely from year to year. About acres were grown in 1915, and good yields and prices were obtained. The seed is sold for chicken feed and for the manufacture of oil. Sunflower seed contains 15 to 18 per cent oil, and the Crop would become better established if the market for the oil could be improved. The yield is about pounds of seed per acre, and the price at the time of this survey was stated to range from 2} to 4 cents per pound. Sun flowers are grown chiefly on sand and sandy loam soils free from alkali. Irrigation is not practiced, but it is believed by some that with irrigation the yields would be increased.
