Sprinkler irrigation in deciduous orchards
Orchard sprinkler irrigation: Studies show supply of readily available soil moisture more important for fruit growth than type of irrigation
by A. H. Hendrickson, F. J. Veihmeyer
Not available – first paragraph follows: Sprinkler irrigation has many advantages in deciduous orchards, but also presents problems not found with surface irrigation.
Alfalfa hay quality: Leaf shatter loss greatest when hay is handled at low moisture content
by John B. Dobie, Luther O. Jones, F. P. Zscheile
Not available – first paragraph follows: Raking alfalfa hay at the wrong time increases leaf shatter—loss of leaves— and may reduce yield by 20% to 30% which means $8.00 to $12.00 of every $40.00 worth of hay may be left in the field.
DDT resistant leafhoppers: Malathon outstanding for grape leafhopper control in tests in areas where DDT resistance was present
by E. M. Stafford, Fred L. Jensen
Not available – first paragraph follows: Field tests and experiences of many Tulare County grape growers in 1952 showed that a 4% malathon dust gave excellent kill of leafhopper adults and nymphs—in both spring and summer treatments.
Acaricides on apples and pears: Tentative ratings of II acaricides given for spider mite control in northern California for 1953 season
by Arthur D. Borden, Harold Madsen
Not available – first paragraph follows: Season to season variance in the effectiveness of new chemicals—used as acaricides for spider mite control on apples and pears in northern California—makes it necessary that only tentative toxicity ratings of the acaricides be listed following each season's field investigations.
Cyclamen mite on strawberry: Successful control by use of natural enemy of pest possible as indicated by results of field investigations
by C. B. Huffaker, C. E. Kennett
Not available – first paragraph follows: The predatory mite—Typhlodromus reticulatus or T. cucumeris—which feeds on the cyclamen mite brought and held the pest under fairly good control in strawberry fields during tests in 1952.
Nematode on cotton: Root-knot nematode control by soil fumigation profitable in Kern County
by D. J. Raski, M. W. Allen, V. E. Burton
Not available – first paragraph follows: Soil fumigation enables a grower to plant' cotton on land infested with root-knot nematode, Meloidogyne incognita var. acrita,—and to obtain yields that give profit above cost of fumigation.
Systox on cotton: Systemic insecticide successful in southern California control tests
by H. T. Reynolds, Van den R. Bosch, E. J. Dietrick
Not available – first paragraph follows: Systemic Insecticides such as Systox— when applied to a plant surface—are absorbed and translocated through the plant tissue.
Walnut aphid study: Shows systox promising material for conditions in northern California
by A. E. Michelbacher, O. G. Bacon, C. S. Davis
Not available – first paragraph follows: A single application of systox was sufficient to control the walnut aphid for the entire season in an experimental orchard at Linden.
Pests of red kidney beans: Increased yields resulted from proper timing and application of control treatments tested in 1952 trials
by Harry. W Lange, Elmer C. Carlson, Ronald S. Baskett
Not available – first paragraph follows: Control of the two-spotted mite and the valley leaf miner—by a single application of an insecticide-acaracide combination—increased yields of red kidney beans in experiments conducted at Linden in 1952.
Efficiency in fruit marketing: Costs of dumping field lugs and receiver-trucking costs studied in relation to packing-house methods
by L. L. Sammet
Part IX of a series of reports on the effects of packing-house equipment, plant layout, and work methods on efficiency and costs. These studies were made co-operatively by the University of California Giannini Foundation of Agricultural Economics and the United States Department of Agriculture under the authority of the Research and Marketing Act of 1946
National and farm incomes: Time-element in relationships of incomes of economic segments and the national income in periods of change
by H. R. Wellman
