Alfalfa and water table levels
California insects: Survey provides accurate data for study of state's insect problems
by Paul D. Hurd
Abstract not Available – first paragraph follows: Insects of economic importance in California–whether native or introduced–have often been studied with almost complete disregard for their relationship to other insect species, largely because of the immediacy of a specific problem.
Alfalfa and water table levels: Studies on effect of alfalfa on water table indicate need for close control of irrigation
by James N. Luthin , William Bianchi
Abstract not Available – first paragraph follows: Alfalfa extracts soil-moisture uniformly to the depth of its root system, and rapidly growing alfalfa will lower the water table appreciably.
Leafy seviiiano olive cuttings: Rooting readily obtained under mist humidification produced satisfactory trees in experiment at Davis
by H. T. Hartmann
Abstract not Available – first paragraph follows: Most varieties of olives can be propagated readily by either leafy softwood cuttings or by hardwood cuttings. However, the Sevillano–one of the leading commercial olive varieties in California–has been difficult to propagate by cuttings; so nurserymen have resorted to grafting on seedlings as a means of propagation.
Rooting paradox walnut hybrids: Promising method for vegetative reproduction of walnut hybrids developed by trench layering
by E. F. Serr
Abstract not Available – first paragraph follows: Twenty-four new shoots were produced by five layered paradox hybrid seedlings in preliminary trials at Davis in 1953.
Aphid resistant to parathion: Strain of walnut aphid in Sun Jose area found to have developed definite resistance to parathion
by A. E. Michelbacher , C. S. Davis
Abstract not Available – first paragraph follows: A strain of walnut aphid–Chroma-phis juglandicola (Kltb.)–encountered in the San Jose area during insect investigations in 1953 exhibited definite resistance to parathion.
Verticillium in chrysanthemum: Costly disease controlled by practice of culture-indexing and soil fumigation with chloropicrin
by Stephen Wilhelm , Richard H. Sciaroni
Abstract not Available – first paragraph follows: Verticillium disease of chrysanthemum can be controlled by fumigation.
Field corn mechanization tests: Low moisture corn harvested with high efficiency in Antelope Valley tests with mechanical pickers
by Lloyd Peterson
Abstract not Available – first paragraph follows: No correlation between moisture content of corn and field losses was evidenced in Antelope Valley field trials– under the conditions of the study–with mechanical harvesters in 1953.
Fluoride lniury to citrus: Effect of air pollutant investigated to learn extent of contamination by component of smog
by F. T. Bingham , R. C. McColloch , G. F. Liebig , A. P. Vanselow
Abstract not Available – first paragraph follows: The fluorine investigations referred to in the following progress report were initiated by the late I. C. Kaudy and continued by the authors.
Lindane repellent to pheasants: Seed grain treated with high levels of Iindane apparently avoided in favor of untreated grain
by Robert L. Rudd , Richard E. Genelly
Abstract not Available – first paragraph follows: Pheasants showed aversion to lindane-treated grain in acceptance tests at Davis.
Earth materials: Growth trials show no benefit to chicks on practical starting ration
by F. H. Kratzer , C. R. Grau
Abstract not Available – first paragraph follows: Results of growth trials with young chicks indicate no justification for the use of natural earth materials in rations for those chicks fed a practical starting ration.
Infectious bronchitis: Vaccines released for growing birds not yet tested for laying hens
by R. A. Bonkowski , D. E. Stover
Abstract not Available – first paragraph follows: Infectious bronchitis is widely distributed in the major poultry raising areas in California. However, all respiratory diseases of poultry are not caused by infectious bronchitis virus. Vaccination with a live virus vaccine against an impending respiratory disease should not be attempted until the respiratory condition for which the vaccine is intended has been correctly diagnosed by a qualified veterinarian or laboratory.
Safflower meal digestion tests: Lambs used in digestion trials with decorticated seed meal to test product as feed for livestock
by Harold Goss , K. K. Otagaki
Abstract not Available – first paragraph follows: Safflower oil-cake meal–a high-protein meal that is a promising source of protein for laying hens–was tested as a possible livestock feed in digestion trials with wether lambs.
Ground-water overdraft: Balance between recharge andraft on ground-water required to correct overdraft in Antelope Valley
by J. Herbert Snyder
