Oats are a crop of Mediterranean origin; not as old as wheat and barley, but their domestication dates back to ancient times. They have many uses: a cereal, a feed grain, green or conserved fodder and, more recently, as a winter cover crop in no-till rotations. Recent changes in farming systems as well as the availability of new cultivars better suited to grazing and mowing have altered the distribution of oats as a fodder: their use may have lessened in some temperate areas, but has greatly increased in many subtropical zones, in both smallholder and mechanized farming systems where previously they were little used. Oats are finding new uses and farmers and researchers are finding ways of integrating them into their production systems wherever they are economically interesting. This book deals with the whole green oat crop used as fodder (whether fed fresh or conserved) and emphasizes their increasing use in smallholder production systems. Oats as a cereal is dealt with in great detail by Welch (1995).
This publication aims to bring together information on fodder oats from all regions of the world; its contributing authors are all regional experts in their field. Much of the Asian work consolidates FAO-supported work carried out in recent years in smallholder farming areas. One chapter is devoted to a worldwide overview of fodder oats; thereafter there are chapters by continent for North America, South America, Europe and Australasia, and country or regional studies from the Maghreb, the Himalaya, Pakistan, China and Japan. A chapter on diseases follows, and the final chapter discusses perspectives for fodder oats.
The genus Avena comprises about seventy species; a few are cultivated. Avena sativa L. (Figures 1.1a, b & c) and Avena byzantina K. Koch sometimes known as the white oat and red oat, respectively, are the main oats grown for fodder and grain. They are hexaploids and modern cultivars may contain genetic material from both species. Avena strigosa, the bristle-pointed oat or black oat, is a diploid. Until recently it was a minor crop of poor soils and harsh climates in parts of Eastern Europe, Wales and some Scottish islands. Recently, A. strigosa has become very important in subtropical and temperate situations as a winter cover crop and forage, as described in Chapter IV. Oats are well suited for use as cover or break crops in winter rotations since they are not susceptible to the major root diseases of wheat and barley; they have a high reputation for weed control, partly due to their high biomass production, but this may be enhanced by allelopathy
