Abstract

A market exists for organically grown, fresh- and processing-market tomatoes. Although information on conventional tomato practices is available from many sources, comprehensive information on organic cultivation practices is difficult to find. Organic tomato production differs from conventional production primarily in soil fertility, weed, insect, and disease management. These are the focus of this publication, with special emphasis on fresh market tomatoes.
