First published in 1956, this handbook is an indispensable, up-to-date companion both in the field and in the marketplace. Topics include the vegetable industry, greenhouse vegetable production, soils and fertilizers, water, pests, weed control, harvesting, storage, and seed production. Packed with quick-access graphs, tables, charts, and line drawings, the 4th edition offers new information on drip irrigation, seed germination, plant tissue and sap testing, windbreaks, and weed management. It also gives advice on allowable pesticide and herbicide use and on the latest worker protection standards. The appendix contains sources of vegetable information, providers of vegetable seeds, periodicals for vegetable growers, and U.S. units of measurement and the metric conversion factors. A change from the spiral-bound 3rd edition is a sturdy, flexible cover to help hold pages flat.
