Wind machines for heat transfer to citrus groves
Concrete pipe irrigation: Successful water distribution systems can be improved further by more adequate designs and installations
by A. F. Pillsbury
Not available – first paragraph follows: Plain concrete pipe systems carry most of southern California's irrigation water but still can be improved in design and installation.
Growth regulators: Effect of 2,4-D investigated in studies on Washington navels
by W. S. Stewart , L. J. Klotz , H. Z. Hield
Not available – first paragraph follows: Satisfactory control of naval orange fruit drop is achieved by California citrus growers who have applied 2,4-D as a plant growth regulator on commercial acreage since 1947.
Heat transfer in citrus groves: Frost protection studies of effectiveness of wind machines alone and in combination with heaters
by F. A. Brooks , C. F. Kelly , D. G. Rhoades , H. B. Schultz
Not available – first paragraph follows: The economic value of frost protection directly depends upon the productivity of the orchard–in quantity and quality. No close averages are available but it can be assumed that the citrus grower who has to heat more than six or seven nights a year probably is losing money on frost protection.
Growth intervals in pasture: Clipping experiments aim at finding the most suitable regrowth periods for California legume-grass mixtures
by M. L. Peterson
Not available – first paragraph follows: Growth intervals of common legume-grass mixtures were investigated to determine the most efficient system of rotation grazing in California's irrigated pastures.
Sucrose spray on tomato: Foliage sprays applied before pulling help transplants to survive storage, heat, other shocks
by Paul G. Smith , Frank W. Zink
Not available – first paragraph follows: Sucrose foliage sprays reduce transplant shock of tomatoes.
Current entomology research: Continuous study aims at liscovery and control of all insects and mites harmful to agriculture in California
by E. O. Essig , Robert L. Metcalf
Not available – first paragraph follows: The Division of Entomology and Parasitology at Berkeley and Davis aims at controlling the agricultural pests of California, with special emphasis on those of importance to the northern part of the state.
Refrigerated locker plants: Preliminary survey indicates operations can be improved by application of industrial engineering techniques
by Louis E. Davis
The following report is based upon a survey undertaken at the request of the Division of Food Technology, University of California College of Agriculture.
Petaluma live poultry auction: Poultry marketing experiment studied for auction volume, grading policy, prices, buyers, producer appraisal
by J. C. Abbott, E. C. Voorhies
