Veterinary science research: Current studies on disease and injury to domestic animals aid in the training of future veterinarians
by George H. Hart
| Full text HTML  | PDF  
Not available – first paragraph follows: The Department of Veterinary. Science conducts research in diseases of all species of farm animals and–through its School of Veterinary Medicine with 40 teaching specialists and a new building at Davis–is equipped to graduate 50 qualified young veterinarians each year.

Apricot irrigation: Tests indicate one irrigation not enough for best results
by A. H. Hendrickson, F. J. Veihmeyer
| Full text HTML  | PDF  
Not available – first paragraph follows: An irrigation before harvest, one about the last week in July and probably one in early September would be a rational irrigation program for apricot trees on deep soil–such as that at Winters.

by E. Laurence Atkins
| Full text HTML  | PDF  
Not available – first paragraph follows: fruit tree leaf roller–Archips argyrospila (Walker) –infested between 2,700 and 3,000 acres of oranges in eastern Los Angeles and western San Bernardino counties in the 1950 season.

Citrus decline virus: Vein clearing and stem pitting as diagnostic symptoms shorten tests
by J. M. Wallace, R. J. Drake
| Full text HTML  | PDF  
Not available – first paragraph follows: Consistent, diagnostic symptoms of citrus quick decline in California have been identified as leaf vein clearing and stem pitting. The symptoms can be induced in a relatively short time, and on seedling plants.

Chestnut production: California leading state but commercial possibilities doubtful
by M. M. Winslow
| Full text HTML  | PDF  
Not available – first paragraph follows: The chestnut will grow satisfactorily in many parts of California but it is questionable whether it can compete with European exports.

Toxaphene for mite control: Effectiveness established as control treatment for cyclamen mite, privet mite, and for mushroom mites
by A. Earl Pritchard
| Full text HTML  | PDF  
Not available – first paragraph follows: Toxaphene– chlorinated camphene–is a relatively new insecticide. In experimental work during the past two years in the San Francisco Bay region, it has shown considerable promise for the control of certain mite pests of ornamental foliage and flowering plants, as well as of mushrooms.

Cabbage seedpod weevil: New enemy of seed crops of Brussels sprouts and other members of mustard family can be controlled
by E. C. Carlson, W. H. Lange, R. H. Sciaroni
| Full text HTML  | PDF  
Not available – first paragraph follows: The cabbage seedpod weevil–Ceutorhynchus assimilis (Paykull)–in 1950, caused losses to the Brussels sprouts seed crop in San Mateo and Santa Cruz counties ranging from 14% to 54%. On broccoli seed at Watsonville one field suffered a 6% loss from the weevil. On cabbage north of Salinas one field had less than 1% loss.

Use of fire in land clearing: Controlled burns must be planned and organized to obtain effectiveness, safety and low cost
by Keith Arnold, L. T. Burcham, Ralph L. Fenner, R. F. Grah
| Full text HTML  | PDF  
Not available – first paragraph follows: The third of five articles reporting the findings in investigations in the effectiveness, the safety and the cost of the use of controlled burning as a tool for land clearing. No attempt is made to provide one formula for prescribed burning in California; each fire is an individual case to be planned on the ground.

Summer weight gain: Brafords, Herefords compared for seasonal gains in Imperial Valley
by N. R. Ittner
| Full text HTML  | PDF  
Not available – first paragraph follows: Brafords gained more during the summer in tests at the Imperial Valley Field Station; yielded more meat when slaughtered but usually brought a little less money per pound than Herefords.
