Rice Quality Handbook
Authors: R.G. Mutters, J.F. Thompson
Description: This 141 page handbook provides detailed information on how to produce high-quality rice from planting to postharvest. It was written primarily for the Sacramento Valley rice industry, but worldwide rice operations, including growers, buyers, operators of dryers, warehouses, and processing operations will benefit from this handbook. Also included are sections on air temperature, humidity, and weather factors, as well as machine harvesting and its effect on quality. It is illustrated with 39 color photographs, 58 graphs, and 35 line drawings.
