Low soil fertility is a fundamental constraint to crop production in western Kenya. Although researchers have developed many soil fertility-improving technologies, the adoption of these technologies is low due to inadequate awareness of the technologies, poor access to requisite resources and uns...

Cratylia argentea (Desv.) O. Kuntze is a drought-tolerant tropical shrub legume that can help to ensure continuity of forage supply in smallholder systems either through direct grazing or as a cut-and-carry plant for fresh foliage or silage. A collection of 38 accessions was characterized agronom...

Agronomic assessment of 76 accessions of tropical fine stem stylo or "tardio" (Stylosanthes guianensis Sw. var. guianensis) was carried out at the Carimagua Research Station in the eastern plains region of Colombia. Of 27 accessions tested for dry matter yield, CIAT 10136 was the highest yielder ...

Deployment of resistant varieties is one major approach to controlling cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis (Xam). To understand the genetic determinism of resistance to CBB, the use of reliable parameters measuring resistance is necessary. In order to te...

This study developed a fast and reliable method of inoculating Brachiaria, a genus of tropical forage grasses, with Rhizoctonia solani, the causal agent of foliar blight disease. Using this method, 42 Brachiaria accessions were inoculated in both field and glasshouse, and their reactions to R. so...

Understanding the distribution of genetic diversity within and among individuals, populations, species and gene pools is crucial for the efficient management of germplasm collections. Molecular markers are playing an increasing role in germplasm characterization, yet their broad application is li...

Diseases of Aeschynomene spp. observed in forage evaluation trials in South America and Florida, U.S.A. are described and discussed. Newly discovered diseases include Polythrincium sp. leaf blotch, Calonectria sp. dieback, and Rhizoctonia solani Kuhn foliar blight. Diseases previously reported fr...
