Growth regulators: Effect of 2,4-D investigated in studies on Washington navels
by W. S. Stewart , L. J. Klotz , H. Z. Hield
pp4, doi#10.3733/ca.v005n08p4

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
pp5-15, doi#10.3733/ca.v005n08p5
Abstract
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.
