Controlled burn costs affected by acreage
Asparagus harvester improved: Increased efficiency of mechanical harvester results of improvements tested in 1954 season
by Robert A. Kepner
Abstract not Available – first paragraph follows: Results obtained during the 1954 season with an experimental asparagus harvester–first used in 1952–indicate that recovery of short spears can be improved and blade life greatly increased by minor modifications.
Yellow clover aphid in state: Pest of alfalfa discovered in California this year found to be spreading rapidly in Imperial Valley
by Andrew S. Deal, R. C. Dickson, H. T. Reynolds
Abstract not Available – first paragraph follows: A new pest of alfalfa, the yellow clover aphid – Therioaphis ononidis (Kalt.)–has arrived in California.
Farm stored grain protection: Moisture content and temperature of stored grain important in prevention of infestation by pests
by A. E. Michelbacher, John E. Swift
Abstract not Available – first paragraph follows: The most important pests of stored grain–such as the granary and rice weevils–either do not thrive or cannot live in grain whose moisture content is 10% or less.
Khapra beetle in California: Eastern hemisphere insect destructive to stored grain, cereal products and foodstuffs established in state
by D. L. Lindgren, L. E. Vincent, H. E. Krohne
Abstract not Available – first paragraph follows: Discovery of the Khctpra beetle–Trogoderma granarium Everts–in barley stored in warehouses in Tulare County, in December 1953, was the first record of this insect occurring in the United States.
Costs of controlled burning: Records reveal comparative costs of controlled burns and wildfire suppression affected by acreage
by L. Burcham, Arthur W. Sampson
Abstract not Available – first paragraph follows: The cost of controlled burning–the planned application of fire to a preselected area to clear the land of unwanted brush–is considerably higher than is usually assumed.
Mineral nutrition of stocks: Need for potassium can be anticipated by soil analysis to determine calcium-potassium ratio
by Garth A. Cahoon, Duane O. Crummett
Abstract not Available – first paragraph follows: Stocks–Matthiola incana – comprise the second largest floricultural field crop, in terms of acreage, produced in California.
Synthetic fertilizer tested: New odorless nitrogen source of low solubility shows promise in investigations with ornamentals
by O. R. Lunt, R. H. Sciaroni
Abstract not Available – first paragraph follows: Uramite–a combination of urea and formaldehyde–is a type of recently developed plastic with many of the favorable characteristics of organic nitrogen.
Sodium in citrus seedlings: Varieties react differently to same concentrations of sodium nitrate in the applied nutrients in tests
by A. R. C. Haas, Joseph N. Brusca
Abstract not Available – first paragraph follows: Sodium has not as yet been found to be an essential element–for health in citrus–although it frequently occurs in varying concentrations in citrus orchard soils.
Sodium in lemon tree collapse: Relationship of sodium content of root tissues to decline and collapse of lemon trees investigated
by D. R. Rodney, S. B. Boswell
Abstract not Available – first paragraph follows: Lemon trees have not responded consistently to applications of any of the nutrient elements in studies at Riverside directed toward learning whether their collapse or decline is affected by nutritional factors. Neither have the trees exhibited symptoms of leaf burn usually associated with an excess of a nutrient element.
Trends in turkey marketing: Efficient procedures in processing for improvement of competitive position of state's turkey industry
by John C. Abbott
