Strawberry Culture: Western United States (open access)

Strawberry Culture: Western United States

Revised edition. "This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those 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 which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3

The Sugar-Beet Nematode in the Western States (open access)

The Sugar-Beet Nematode in the Western States

"The sugar-beet nematode is one of the most serious of the beet pests. It appears to have been imported with some shipments of beet seed many years ago. It has been found widely scattered in four of the western sugar-beet States and probably exists in other States where beets have been grown for several years. The sugar-beet nematode is the cause of a great deal of loss to the beet grower through reduction of his tonnage, and of a corresponding amount of loss to the sugar producer through reduction of the output of sugar. This bulletin treats of the nature and distribution of the sugar-beet nematode, indicates the most probable means by which this pest is spread, and suggests preventive measures and practical means of control." -- p. 2
