Presents the results of investigations on the relative distribution of the various phosphorus forms, fixing capacity and status of some Ethiopian highland Vertisols.
Summarises available information on the P status of soils, effect of P application on nodulation, dry-matter and seed production, crude-protein and dry-matter digestibility; use of slow release sources of P; differences among species and varieties in their response to P ; assessment of P status o...
This paper is comprised of five parts. The first part discusses the role of legumes in sustainable soil management and crop-livestock production. In this part, strategic use of legumes, selection of forage legumes to sub-optimal soil conditions, use of appropriate rhizobium, response of legumes t...
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...
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.
Crop livestock production systems in Africa are constrained by wide fluctuations in the quality and quantity of feed resources during the year and by the low availability of nutrients, especially nitrogen and phosphorus, in most soils, which threatens the sustainability of primary production. In ...
