Since the 1960s Australia has played a key role in the development of tropical forage varieties for livestock systems in the developing world. Australian research agencies (especially the Commonwealth Scientific Industrial Research Organisation (CSIRO) and the International Center for Tropical Agriculture (CIAT) compiled the largest tropical-forage germplasm collection in the world, with over 30,000 entries. While this collection contained plants that had the technical potential to improve smallholder livestock production in South-East Asia, the potential was unproven. |

To most smallholder livestock producers in Southeast Asia, planted forages are much more than simply a new variety of a crop with which they are already familiar. 'Planting forages' is an entirely new concept, requiring major changes in the way farmers think about and manage their crop-livestock systems. Such significant changes do not happen easily unless there are strong pressures for change...and these pressures are coming fast in Southeast Asia, in the form of disappearing traditional feed resources and rapidly increasing demand for livestock products. The most promising way to support the emergence of significant impacts from forages in smallholder livestock systems comes from matching the best varieties available with participatory approaches to research and extension. Since 1995, CIAT has been working with national partners throughout the region to apply this approach in six countries of Southeast Asia. To date two studies have documented and assessed the economic and social impacts of the new forage technologies on the livelihoods of smallholder farmers. This publication refers to the second study carried out in Mindanao, Philippines, and Tuyen Quang, Vietnam. Participatory evaluation tools together with conventional survey techniques were used to compare the livestock production systems of early and recent forage adopters. Results were stratified by wealth categories and other important cultural factors. The studies document the scale of social and economic impacts and highlight lessons that have emerged for future development. |

The present bibliography, developed in collaboration with the University of Hohenheim, Germany, compiles citations related to information on the tropical legume species Desmodium heterocarpon subsp. ovalifolium. The bibliography attempts to examine the species and its use as cover crop and forage legume over the past decades. Several international literature databases were reviewed (e.g. AGRICOLA, AGRIS, CAB) as well as those of local scientific institutes and universities in Central and South America. References considered were those where the species was more than just mentioned and where the information provided was regarded as useful. Only a few, especially important botanical references are included. Special emphasis was placed on the assessment of so-called 'grey literature', which represents a neglected but often valuable source of information especially regarding (1) countries with a burgeoning publication culture and (2) species of regional importance. The bibliography owes much to the GreyLit project of the Centro Internacional de Agricultura Tropical (CIAT)'s Library and Communications Unit where all references are available. |

Although many consider farmer participatory research (FPR)-where farmers and researchers work together to develop new agricultural technologies-as "bringing substantial benefits" to farmers, others suggest it has "still to live up to its promise". FPR must therefore be carefully monitored and evaluated to ensure "quality control" and, particularly, to document and evaluate impact. This publication outlines the development of a participatory monitoring and evaluation (PM&E) framework for such participatory research programs as the "Forages for Smallholders Project" (FSP), begun in 1995 in Southeast Asia. Examples are drawn from the FSP's fieldwork on extensive upland farming systems at two contrasting sites (Malitbog, Philippines, with a wetter climate, and M'Drak, Vietnam, with more acid soils), the presentations of a 5-day workshop, and selected literature on PM&E. Part A of the publication presents the conceptual and practical issues involved in developing PM&E for the FSP. Part B reviews a range of techniques for implementing PM&E. The publication developed out of a collaborative project between CIAT and the University of Queensland, with funds from the ACIAR. |

TROPILECHE's Project on Feed Systems with Legumes to Intensify Dairy Farms, based at CIAT, reports on 4 years (1996-2000) of activities. To improve cattle feed on Latin American dairy farms, the Project is applying a strategy that involves evaluating new forages for grazing, on-farm evaluation of new legumes as components of the grazing system, analyzing the technologies' economics and adoption, and studying the impact of improved forages on dairy production. Also discussed are five case studies involving grass/legume pastures; urea levels in milk; legumes as feed for preweaned calves, milking cows, and hybrid cows; legumes as green manure and for fixing N before planting rice; and Cratylia and sugarcane for increasing dairy production during the dry season to supply an artisanal cheese industry. The last case also demonstrated how an improved technology can have an economically positive impact on local agriculture. The Project also developed several communications media for Project users, launched two cultivars (Pasto Toledo and Veraniega), initiated legume seed production, and established alliances with public and private institutions. |

[Genotype-by-Environment Interaction in a Collection of the Legume Desmodium ovalifolium: Proceedings of the First Workshop, held 19 March 1996 at CIAT, Cali, Colombia] Desmodium ovalifolium as a forage legume and cover crop has great potential for tropical America. It is adapted to acid low-fertility soils, has a stoloniferous growth habit, and tolerates heavy grazing and shade. However, the forage has high tannin contents, making it indigestible and leading to poor animal performance. Consequently, it has been relatively neglected in recent research, and little is known about this species or of the factors that influence its acceptability and nutritional quality. A collaborative project, financed by Germany's GTZ, was initiated in 1995 to study the genotype-by-environment interaction in a selected collection of D. ovalifolium. The project held its first workshop on 19 March 1996 at CIAT to review the state of knowledge on D. ovalifolium in general, discuss activities conducted so far (to 1995), and plan future activities. The workshop also aimed to integrate the project's participants and different initiatives, report on preliminary results, and promote collaboration both within the project and with people as yet uninvolved. These proceedings bring together the 20 presentations given during the workshop. |

Grasses of the Brachiaria genus are now highly important forages in tropical America. The book discusses their taxonomy, application of molecular techniques for genetic improvement, exploitation of Brachiaria spp. for improving the productivity and sustainability of pasture-based livestock production in the lowland tropics, the biology and agronomy of Brachiaria, and the ecological risks involved in introducing exotic species to the American savannas. The need to compile widely scattered literature and outline future research priorities brought researchers to CIAT in 1994 for a workshop, coordinated by CIAT and EMBRAPA, and one of the few on forages that has been supported by the private sector. Also available in Spanish. |

[The Potential of the Cratylia Genus as Leguminous Forage] The Cratylia genus comprises drought-tolerant legumes that are rich in proteins. It can be exploited as food for humans and fodder for animals living in semiarid areas such as Northeast Brazil. This ecologically plastic genus (characterized by homeostasis during development) is also adapted to the Brazilian Cerrados and certain niches in the Amazon Basin. Brazil currently has programs to study this native germplasm to prevent its genetic erosion and to strategically increase the country's offer of products for its population's direct or indirect consumption. This would reduce the high use (already at 80%) of exotic species. A symposium was held in July 1995, in Brasilia, DF, under the sponsorship of EMBRAPA, CENARAGEN, and CIAT, and with the participation of other institutions. Its theme was the collaboration for research on aspects ranging from the genus's geographical distribution, through applying biotechnology for its improvement, and final uses. |

A World List of Fungal Diseases of Tropical Pasture Plants brings together many unpublished records from the International Mycological Institute, the author's personal records and Australian records as well as records resulting from detailed searches of published information. This list includes diseases recorded on 429 species of 37 genera of legumes (for example: Aeschynomene, Centrosema, Desmodium, Leucaena, Macroptilium and Stylosanthes) and on 667 species of 31 genera of grasses (for example: Andropogon, Brachiaria, Digitaria, Panicum, Paspalum, Pennisetum and Setaria), their distribution and a comprehensive bibliography of more than 300 references. As the first list of fungal diseases of tropical pasture plants, it should prove a valuable reference to pasture scientists and quarantine officers throughout tropical countries and especially where pasture germplasm introduction programmes are in progress. |

[Manual for agronomic evaluations: International Tropical Pastures Evaluation Network] This manual describes the methodology for conducting agronomic evaluations of regional trial types A and B conducted by RIEPT (International Tropical Pastures Evaluation Network). By using standard techniques for evaluating materials in these trials, network members will obtain more reliable information that can be compared across sites, and will help develop materials more suitable for adaptation to different Latin American ecosystems. The data collected will result in scales of economy for collaborative research. A product of a 1979 work plan, the methodology's final objective is to increase livestock productivity (per animal and per unit area) by incorporating marginal lands that encompass 1000 million ha of savannas and forests in which predominate acid and low-fertility soils, while using minimal inputs and adapted forage germplasm. |

El propósito de este ciclo de tres conferencias es explicar en una forma fácil y clara: a) Cuál es el papel de "Biometría" en CIAT. b) Cuál es el proceso a seguir cuando se desea efectuar un experimento. c) Cuál es el uso de la Estadística y la Probabilidad en la experimentación. d) Cuáles son los diseños estadísticos más utilizados en experimentación agrícola y pecuaria. e) Cómo analizar algunos diseños balanceados básicos. Aunque el estudio del Diseño y Análisis de experimentos conlleva una teoría matemática muy sólida y elegante, no es nuestro deseo profundizar en ella a través de estas conferencias. Más bien, explicaremos cuáles son los diseños básicos que existen, cuándo se pueden usar y cómo se deben analizar. |
