Presents the results of investigations on the relative distribution of the various phosphorus forms, fixing capacity and status of some Ethiopian highland Vertisols.
This chapter summarises the experience of a research project for developing and disseminating technologies for better management of Vertisols for improving productivity. Topics of discussion include Vertisol technology Development and testing in Ethiopia; the adoption pathways for the BBM package...
Two greenhouse experiments were conducted to investigate the effect of phosphorus application and Rhizobium inoculation on the growth and nitrogen fixation of three tree legume species on a highland vertisol. The first experiment involved Sesbania sesban and S. goetzei, the second Leucaena panicu...
In Ethiopia vertisols of the highlands are vast and underutilized. For increasing production on highland vertisol, a joint vertisol project undertook a range of integrated research activities. ILCA's research in this partnership project, the integrated research activities, the research approach, ...
Discusses low cost animal drawn implements developed by the Vertisol team in Ethiopia for land shaping, planting, weeding, minimum tillage and for constructing water reservoirs in resource poor farming situations.
This paper summarises how an international research centre may hope to be effective by forging partnership arrangements with national research systems and with research institutions in industrialised countries. A major requirement for an effective partnership is that it is an integral part of the...
Reviews vertisol management research experiences in Ethiopia. Discusses the relative potential of vertisols and Development of the Ethiopian Vertisol Program. Examines integration of research programmes and technology extension. Presents data on th economic evaluation of improved, animal-powered ...
Reports some responses of three prominent African clovers, viz, Trifolium tembense, T. rueppellianum and T. steudneri native to Ethiopia to phosphorus and combined N/P fertilizers on a P-deficient vertisol at the ILCA headquarters site.
