Blood-spotting in chicken eggs can be controlled by breeding. Heredity is the most important known factor responsible for the tendency of birds to produce blood-spotted eggs. To study the influence of genetic differences between birds with respect to this common defect, a selection experiment was undertaken.

Lettuce growth rates depend primarily on the month of planting.

Certain insecticides may produce invisible–internal–injury to the citrus plant.

Lithium toxicity in citrus was recognized for the first time in the field in Santa Barbara County. The element apparently came from irrigation water.

Commercial navel and Valencia orange groves in the San Joaquin Valley were used in experimental applications of parathion for citricola scale control in field tests during the period from 1947 to 1950.

Citricola scale–Coccus pseudomagnoliarum (Kuw.)–in citrus growing areas of California is still resistant to hydrogen cyanide–HCN–fumigation.

The dust–Of the dust storms in the southern San Joaquin Valley the past several years–comes from two sources: 1, the Westside Plains and 2, from farm leveling operations and subdivision development.

Five field stations are an integral part of the College of Agriculture.

Eureka lemons to be used for processing are profitably grown on Sampson tangelo stock, while fruits from Rough lemon stock are not desirable.

The olive is a new host of the citrus-root nematode.

No evidence of toxicity was found in gold fern and bird's foot fern, two plants suspected to cause jimmies–or jitters– in cattle moved to and from mountain ranges.

Swine production can be improved by using purebreds with records consistent in prolificacy, milk production, and type.
