Design of livestock shades: Construction and location of shades contribute to animal comfort and maintenance of feed intake
by C. F. Kelly, T. E. Bond, N. R. Ittner
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: High weather temperatures at certain seasons may turn profitable livestock enterprises into losses, even though feed and labor are plentiful.

Use of moles for subirrigation: Sutter Basin beans adequately irrigated by improved procedures in ditching and use of artificial moles
by D. W. Henderson, J. H. Lindt, R. C. Pearl
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: Production of beans on the rice lands of the Sutter Basin–as part of a crop rotation program–presents a difficult irrigation problem.

New pest of ladino clover seed: Cultural practices believed best control of clover case bearer now established in certain counties
by Ray F. Smith, Lloyd Andres
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: The clover case bearer–Coleophora spissicornis Haworth–mainly associated with white clover–Trifolium repens–but also reported to attack red clover–T. pratense and T. arvense– seems to be established as a pest of Ladino clover seed in the Sacramento Valley.

Wind machine tests in citrus: Frost protection studies in 1954 confirmed earlier findings next to be investigated in deciduous trees
by F. A. Brooks, D. G. Rhoades, A. S. Leonard

Summary not Available – first paragraph follows: Tests of wind machines made in January and February, 1954, at the University of California Citrus Experiment Station, Riverside, confirmed and extended previous tests of multiple machines.

Valencia fruit sizes increased: Calcium acid phosphate found effective in outdoor cultures of pure silica sand and nutrient solution
by A. R. C. Haas, Joseph N. Brusca
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: The Valencia fruit size problem has interrelationships of various factors, and to learn how certain ones operate–when as many as possible of the usual complicating factors are removed–a series of experiments were set up using pure silica sand and nutrient solution. This type of experimental approach makes it possible to synthesize some of the actual orchard nutritional conditions in certain areas where large sizes of fruit often predominate.

Codling moth at linden in 1953: Uccessful control sprays applied in experimental orchard in season of serious infestation at Linden
by A. E. Michelbacher, Earl Oatman
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: An outbreak of the codling moth on walnuts in 1953–the most destructive infestation since 1948–was successfully controlled with a single treatment in the experimental orchard at Linden, whether the sprays were applied with a conventional or with an air carrier sprayer.

Biological control of fig scale: From 67% to 100% of scale on twigs sampled in 1954 at colonization sites was found to be parasitized
by Richard L. Doutt
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: Two small colonies of Aphytis “C,” a wasp parasite of the fig scale–Lepido-saphes ficus (Signoret)–released in the San Joaquin Valley, one at Merced and the other near Fresno, demonstrated what is almost an axiom in biological control work: if a parasite is destined to succeed, it will take hold immediately after an adequate release on susceptible hosts.

Temperature and lettuce losses: Variables of time and temperature as they affect deterioration of harvested lettuce investigated
by Harlan K. Pratt, Leonard L. Morris, Carl L. Tucker
| Full text HTML  | PDF  
Summary not Available – first paragraph follows: Lettuce–like most leafy vegetables– deteriorates rapidly and steadily after harvest. Loss of quality is inevitable and can only be minimized by rapid handling and with the best possible storage conditions.
