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...

Five accessions, comprising Aeschynomene histrix, Centrosema acutifolium, Centrosema pascuorum and Stylosanthes guianensis together with Stylosanthes hamata cVerano were evaluated over 2 years for use in fodder banks in subhumid Nigeria. The most promising accession was A. histrix 112463 with yie...

Accessions of Aeschynomene histrix, Centrosema acutifolium, C. pascuorum, Stylosanthes guianensis and S. hamata

Trials were conducted at 7 sites in northern Nigeria to identify forage legumes as alternatives to Stylosanthes hamata cVerano. Initial screening of 46 accessions at each site led to the identification of the best 8 for each site. These were then tested for 4 years, the first 2 with careful manag...

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...

A feeding trial with sheep was carried out at the Centro Internacional de Agricultura Tropical (CIAT) in Colombia to investigate the concept of using mixtures of sun-dried tropical shrub legumes to dilute tannin levels in the diet and improve nitrogen (N) utilisation by ruminants. Intake, digesti...
