This book has been written primarily for the students of Horticulture/Agriculture, research workers and growers, and provides useful information on Medicinal and Aromatic plants of Umbelliferae to develop improved technology to enhance the prodctivity of these plants. The writing of this book was originally undertaken at the invitation of University Grants Commission, New Delhi as a part of their programme for the preparation of university level books by Indian authors. Umbelliferae family comprises about 300 genera and 3000 species of herbs some of which are ecnomically well known. The most important among these are Ajowan (Trachyspermum ammi L.) Syn. (Carcum copticum L.); Caraway (Carum carvi L.); Celery (Apium graveolens L.); Coriander (Coriandrum sativum L.); Cumin (Cuminum cyminum L.); Dill seed (Anethum graveolens L.); Fennel (Foeniculum vulgare Gearten); Anise (Pimpinella anisum L.); Honey plant (Ammi majus L.); Asafoetida (Ferula asafoetida L.) and Angelica (Angelica archangelica L.). In the literature, it is reported that the yield of these plants is very low due to lack of commercial and systematic cultivatin of these crops. It is an establised fact that cultivation of these plants with improved technology helps in bringing about an overall improvement in production and yield of their oil. Very scanty information is available in the literature regarding production technology of these crops. Besides, whatever information available is generally meager and scattered. Am effort has been made to compile the scattered information in this book, which can be used as reference material in the universities and colleges. This book will also provide the latest information on improved cultivation technology to research and extension workers and growers of these crops.
