This manual, prepared for use by Peace Corps volunteers, provides background information and practical knowledge about crop production. The manual is designed to convey insights into basic crop production, principles, and practices. Primary emphasis is given to providing explanations and illustrations of soil, plant, and water relationships as they affect crop production. The content is presented in as nontechnical language as possible. Each of the seven units of the text are complete, substantially self-contained, and provide information, tables, and illustrations. The units cover the following topics: soils, plants, entomology, cereal crops, pulse crops, sugar and fiber crops, and oil crops. A glossary of terms used in agronomy completes the manual. (KC)
