Legumes in Agriculture Apart from the publication International Institute of Agriculture The Use of Leguminous Plants in Tropical Countries as Green Manure, as Cover and as Shade (Rome, 1936)* no comprehensive review of tropical legumes has yet been attempted. This is done here against a background of information and practices which have been developed in other regions. Now that it is completed, it is possible to see how little is known about legumes in the tropics and sub-tropics. Again, the chief limiting factors appear to be social and economic rather than a lack of leguminous species for all purposes apart from intensive grazing as understood in the white clover zones of the world. Within the existing genera and species, there is almost certainly great scope for the selection and breeding of improved strains adapted to different climates, soils and types of utilization. * Available from FAO or through all Sales Agents. The first part of the book deals with the economic botany, ecology and biotic relationships of legumes their relation to alternate husbandry, association with grasses, use as animal feed. Their particular importance to the tropics and sub-tropics, and the lack of modern data on tropical legumes, made FAO distribute a questionnaire to all tropical countries. The resulting material is to be found throughout the book, but particularly in a chapter which summarises the local practices in the use of legumes, and lists the species concerned. Chapters on poisonous plants and weeds, the significance of symbiotic nitrogen fixation, plant introduction and exploration, adaptation, strain variation and breeding, investigation and testing of improved strains, and the production of seed complete the first part. Part II lists the principal legumes, with special emphasis on those of the tropics and sub-tropics, and an appendix tabulates the species, indicating plant characteristics climatic adaptation, soil adaptation, utilization, number of seeds per pound and seeding rates in pounds per acre. $3.00. 15s.

Agricultural Development and Rural Reform in Denmark FAO is now giving considerable attention to land tenure problems. This monograph covers not only the subject of land tenure, but also several aspects of agricultural development in Denmark closely associated with this subject, so that it can be considered as a significant contribution to the work of FAO in this field. 1953, viii + 320 pp. (E). $3.00. 15s. |
