Excerpts from the report Introduction: California is by far the most important source of cauliflower, but producers in that State have realized a steadily diminishing return from their output over the last 11 years. There have been times during the shipping seasons when it was uneconomical to harvest all of the crop and large quantities of cauliflower had to be abandoned in the field. Although this was due in part to a decline in wholesale prices at the terminal markets, the unfortunate situation could be attributed more directly to steadily mounting costs of containers, packing, shipping, and transportation. Established shipping practices were reappraised and double-layer packing of closely trimmed cauliflower heads in broccoli crates, of somewhat larger capacity than the present cauliflower crate, was tried out and the technical aspects of the problem evaluated by the field personnel of the Western Growers Association. The results of those studies and experiments are set forth in this report.
