||Since 1971 CIMMYT has been helping the governments of Tunisia and Algeria test the potential value of a rotation of winter annual legume pasture (Medfoago spp. ) and wheat for replacing the present weed_ fallow-wheat rotation currently used in these countries. During March-April 1974, Mr. Edward D. Carter, agronomist, Waite Agricultural Research Institute, visited Algeria as a CIMMYT consultant to study the potential for increasing crop and livestock production in Algeria if a legume pasture-wheat rotation was adopted. Because of the potential value of this cropping system in other areas of the Near East and Mediterranean region, and the interest already generated by the research in Tunisia and Algeria, CIMMYT has decided to publish and distribute Mr. Carter's report. CIMMYT appreciates the enthusiastic, thorough, and expert manner in which Mr. Carter accomplished this survey and report, and wishes to acknowledge the cooperation of the University of Adelaide in making Mr. Carter's services available. The financial assistance provided by the Ford Foundation to carry out adaptive research on the farming system and to support this survey of the system's potential is gratefully acknowledged.
