This book describes in detail the plants that feature prominently in agriculture together with the products which are obtained from them. The opening chapter on world population and food supply is followed by a general introduction to plant structure. The major part of the book considers economically important field crops and pasture plants of temperate and subtropical regions on a family-by-family basis. The book concludes with a discussion of physiological principles of crop growth and yield. This is an introductory text, suitable for the teaching of agricultural botany to undergraduate students, and is intended to bridge the gap between classical botany and agronomy.
