Flower colour has been used as a simple morphological marker for genetic studies in many species, including legumes. In several tropical forage legumes, grown to evaluate their environmental adaptation or forseed increase, white-flowered plants were observed when the predominant flower colour was...

We conducted an experiment to determine the effects of concentration and astringency of extractable and bound condensed tannins (CT) in tropical legumes on intake, digestibility, and nitrogen (N) utilization by sheep. The test legumes (Desmodium ovalifolium and Flemingia macrophylla) had similar ...

A trial with sheep (housed in metabolic cages, and fitted with ruminal and duodenal cannulas) fed sun-dried forage of two Calliandra calothyrsus provenances (San Ramon —CIAT 22310 and Patulul CIAT— 22316) harvested in sites with contrasting soil fertility was carried out to further define the bio...

En épocas de lluvia (mayo de 2006) y de sequía (agosto de 2006), en tres sitios de la zona de ladera de los municipios de Bolívar, Sevilla y El Dovio, se evaluó mediante metodologías participativas el proceso de adaptación de tecnologías forrajeras. Se aplicaron evaluaciones abiertas, absolutas y...

En el CIAT, Centro Experimental, Estación de Santander de Quilichao, (Cauca, Colombia) durante 1980 y 1981 se observó la presencia de marchitez en plantas de Zornia spp., asociada a Corynebacterium flaccumfaciens. En razón de ese registro y del riesgo que implicaba su presencia en uno de los siti...

A short-term improved fallow system based on forage legumes is suggested for crop-livestock farming systems in subhumid West Africa targeted to enhance soil fertility and dry season feed for cattle. At two sites, 13 legume species were compared with the natural fallow vegetation, the nutritive va...

Populations of Legume Nodulating Bacteria (LNB) were assessed under glasshouse conditions in soils collected from selected landuse systems in Taita Taveta district, Kenya. The populations were estimated by the most-probable-number (MPN) plant infection technique using Macroptilium atropurpureum (...

A short-term improved fallow system based on forage legumes for enhancing crop and livestock components of mixed farming systems was tested in the subhumid zone of West Africa. As part of the evaluation, the ability of 11 legume species (Centrosema macrocarpum, C. pubescens, Stylosanthes guianens...

A glasshouse experiment was conducted to determine how reduction conditions would affect plant nutrient availability and uptake in a red-yellow latosol (Acrustox). Soil analysis showed that the most important changes were a marked increase in extractable iron and an inhibition of nitrification. T...
