The Turnip Aphid in the Southern States and Methods for Its Control
"The turnip aphid is one of the most destructive and widely distributed pests of turnip, mustard, radish, and related crops in the United States. It causes heavy losses to growers of these crops every year, especially in the Southern States. Dust mixtures containing derris, cube, or nicotine, and sprays containing derris or cube, will control the turnip aphid when applied properly. The first application of insecticides should be made when the plants are very small, and additional applications should be made at intervals of 7 to 14 days up to the time of harvest. To provide for effective application of insecticides, the seed of susceptible crops should be planted in drills, with the rows spaced uniformly apart. The following cultural practices aid in the successful production of crops exposed to turnip aphid attack: (1) A well-prepared, fertile seedbed to produce thrifty and rapidly growing plants, (2) planting the seed in drills to permit cultivation, (3) harvesting early to shorten the period of exposure to infestation, (4) destroying crop remnants to eliminate a common sources of infestation to succeeding crops, and (5) applying a nitrogenous fertilizer to stimulate plant growth." -- p. ii

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria
From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

Strawberry Culture: Western United States
Revised edition. "This bulletin applies both to the western portions of the United States in which ordinary farm crops are grown largely under irrigation and to western Oregon and Washington where irrigation is not essential for strawberry production but may be profitable. It describes methods practiced in the more important commercial strawberry-growing districts of the West; it aims to aid those persons familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those of irrigating other crops. Details must necessarily be governed largely by the character of the crop grown. Because strawberries in the humid areas frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove helpful to many growers in those areas who could install irrigation systems at small expense. This bulletin gives information on soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, shipping, and utilization." -- p. ii

Strawberry Culture: Western United States
Revised edition. "Strawberries can be grown in those parts of the western Untied States in which ordinary farm crops are irrigated as well as in western Oregon and Washington, where irrigation is not essential but may be profitable. The principles of irrigating strawberries are essentially the same as those for other crops. Because strawberries are sensitive to the alkali salts that irrigation brings to the surface, such salts must be washed out or skimmed off. The strawberry grower, after choosing a suitable site and preparing the soil carefully, should select varieties adapted to his district and needs. He should use plants that are disease-free. In California, southern Arizona, New Mexico, and Texas the plants should have undergone a rest period. Usually the growers plant during the period of greatest rainfall. By using the recommended systems of training and care before, during, and after setting of the plants and the suggested methods of decreasing diseases and insect pests, he should obtain better yields. A grower can furnish consumers a better product by using good methods of harvesting and shipment. He can prolong the fresh-fruit season only a little by the use of cold storage, but he can extend his market by …

Muscadine Grapes
Revised edition. "Muscadine grapes, which are native to the southeastern part of the United States, thrive in most soils of that region. They can be grown successfully in the Southeastern States, where American bunch grapes do not thrive. furthermore, they are suitable for home gardens as well as for commercial use. In fact they are perhaps the most satisfactory of all fruits for the home garden in this region. They cannot be grown, hoever, where temperatures as low as 0 °F occur habitually and may be injured at somewhat higher temperatures. Muscadine grapes are relatively uninjured by diseases and insects and produce well with a minimum of care, but they resopnd favorably to the good cultural practices recommended in this bulletin. The varieties described or listed produce fruit suitable for making unfermented juice, wine, jelly, and other culinary products and for eating fresh over a long season." -- p. ii
