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...

Investigates Nitrogen and Phosphorus transfers in a crop - livestock system in the subhumid zone of Nigeria. Estimates N and P removed from cropland during crop residue grazing and returned to the land through manure, and the contribution crop residues make to cattle diet during the dry season.

Eleven Sesbania sesban and three S. goetzei accessions were evaluated for dry matter (DM) yield in response to phosphorus (P) application and fodder quality on an acidic Nitosol at Soddo, in the Ethiopian highlands. The soil at this site is known to be P deficient and to have high ability to fix ...

In the subhumid zone of Nigeria S. guianensis cv Cook, S. Guianensis cv Schofield and S. hamata cv Verano produced low dry matter yields. The role of P in limiting yields was investigated in a field experiment at Kurmin Biri, Kaduna State, Nigeria. Four levels of P<sub>2O<sub>5, zero, 40, 80 an...

This paper ilustrates the principle determining cropping systems for Vertisols by reviewing work in the highlands of Ethiopia. The types of cropping systems that can be applicable in the different Vertisol environments are briefly described. These cropping systems include single cropping; multipl...
