Self-fed salt concentrate mixtures
Salt concentrate mixtures: Consumption of self-fed supplemental feed mixtures can maintain range animals on good nutrient level
by D. T. Torell , Wm. C. Weir
Abstract not Available – first paragraph follows: Range ewes can be kept on the desired plane of nutrition–while consumption of supplemental feed is regulated–according to results obtained in tests with self-fed salt concentrate mixtures.
Imperial valley lamb feeding: Data on rates of gain per month and per acre obtained in winter season feeding trials on alfalfa pasture
by N. R. Ittner , Wm. C. Weir
Abstract not Available – first paragraph follows: Lambs grazing on alfalfa pasture in the winter season of the Imperial Valley gained 9 to 10 pounds per month during two trials. The pasturage had a carrying capacity of five to six lambs per acre, and produced 40 to 50 pounds of lamb per acre per month.
Heating poultry drinking water: Electrically heating poultry watering systems by different methods tested for economy of operation
by John B. Dobie , Leroy C. Kleist
Abstract not Available – first paragraph follows: Tests on three methods of heating poultry watering systems electrically indicated that it was most economical to run the heating cable through the water pipe.
Blackberries resistant to wilt: Certain varieties of the trailing berry resistant to Verticillium wilt may be grown in infested soil
by Stephen Wilhelm , H. Earl Thomas
Abstract not Available – first paragraph follows: Boysen, Nectar and Young, the trailing blackberry varieties most widely planted in California are highly susceptible to the Verticillium wilt disease.
Poinsettia bud initiation dates: Study of bud initiation dates enables growers to produce and time better poinsettia flowers
by A. M. Kofranek , R. H. Sciaroni
Abstract not Available – first paragraph follows: The poinsettia–grown especially for the Christmas holiday season–is valued at approximately $250,000 annually. It is the third ranking pot plant crop in California with over 60% of the plants being grown in the San Francisco Bay Area.
Control of the frosted scale: Tests in southern California indicate parathion sprays effective treatment against pest on walnut
by J. C. Ortega
Abstract not Available – first paragraph follows: The frosted scale–Leeanium pruninosum Coq.–is a large, convex black scale about 5/16” long and is covered with a frostlike wax. The eggs are oval and pearly white when first laid, but as they develop under the female scale they turn darker. When ready to hatch they are pale brown in color. The hatch starts early in May and continues into July or–in some areas–into August.
Oxidation of sulfur in soils: Nitrogen losses during oxidation may cause temporary setback to plants following applications of sulfur
by J. P. Martin , J. O. Ervin
Abstract not Available – first paragraph follows: Nitrogen disappears especially rapidly from soils which are naturally high in mineral nitrogen or which receive heavy applications of fertilizer nitrogen.
Infiltration rates: Effect of wetting agents in water on infiltration rates into soils
by O. R. Lunt , M. R. Huberty
Abstract not Available – first paragraph follows: Laboratory and field studies indicate there is little, if any, increase in the water infiltration rate into soils because of decreased surface tension of water treated with wetting agents.
Brassica-root nematode here: Pest formerly unknown in the United States found to be established in fields in Half Moon Bay area
by D. J. Raski , R. H. Sciaroni
Abstract not Available – first paragraph follows: The Brassica-root nematode–Heterodera cruciferae Franklin, 1945– formerly believed to be in England and Wales only, is in San Mateo County.
Seasonal use of dairy products: Studies of Sacramento families showed how uses of dairy products varied with season
by Jessie V. Coles
Abstract not Available – first paragraph follows: Surveys of 262 families in Sacramento revealed that they used 16% more of 22 dairy products in one week in August than they did in one week in January.
