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...


Haque, I.Nnadi, L.A.Mohamed-Saleem, M.A.[Phosphorus management with special reference to forage legumes in sub-Saharan Africa]Phosphorus management with special reference to forage legumes in sub-Saharan Africa

Examines the potential of forage legume-cereal intercrops in enhancing soil fertility and increasing crop and livestock production in sub-Saharan Africa. Discusses inter/relay cropping systems, forage legumes in cereal systems, improvement of feed quality and enhancement of soil fertility and com...


Nnadi, L.A.Haque, I.[Forage legume-cereal systems: Improvement of soil fertility and agricultural productivity with special reference to sub-Saharan Africa]Forage legume-cereal systems: Improvement of soil fertility and agricultural productivity with special reference to sub-Saharan Africa

Phosphorus (P) is required to improve soil fertility for food and feed produciton in sub-Saharan Africa, but the high cost of conventional, water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effectiveness, in terms of seed product...


Haque, I.Lupwayi, N.Z.Ssali, H.[Agronomic evaluation of unacidulated and partially acidulated Chilembwe rockphosphates for clover seed production]Agronomic evaluation of unacidulated and partially acidulated Chilembwe rockphosphates for clover seed production

This study is conducted to develop simple, rapid but efficient bio-nutritional techniques using nutrient solution, soil and sand cultures to assess the adaptability of nutrient solution, soil and sand cultures to assess the adaptability of forage crops to various soil conditions, to determine the...


Aduayi, E.A.Haque, I.[Screening forage legumes germplasm to low soil fertility: V. Highland Leucaena germplasm tolerance to phosphorus deficiency in solution, soil and sand culture(ILCA PSD Working Documents Nos. 18-21 1992)]Screening forage legumes germplasm to low soil fertility: V. Highland Leucaena germplasm tolerance to phosphorus deficiency in solution, soil and sand culture(ILCA PSD Working Documents Nos. 18-21 1992)
Haque, I.[Nutrient management & feed improvement in crop-livestock systems of sub-Saharan Africa: present status and future outlook]Nutrient management & feed improvement in crop-livestock systems of sub-Saharan Africa: present status and future outlook

Reviews the present state of knowledge about the biological contribution of nitrogen by forage legumes in sub-Saharan Africa; indicates the main factors limiting the contribution of biological N by forage legumes; highlights the potentials of legume - food crop - livestock interactions in various...


Haque, I.Jutzi, S.C.[La fixation de l'azote par les legumineuses fourrageres en Afrique subsaharienne: Potentialites et contraintes]La fixation de l'azote par les legumineuses fourrageres en Afrique subsaharienne: Potentialites et contraintes

Reports on the Nitrogen contribution of one forage and three grain legumes, viz, vetch (Vicia villosa), wheat, faba beans, peas & lentils, to a subsequent maize crop in the Ethiopian highlands.


Haque, I.Jutzi, S.C.[Contribution en azote de quatre legumineuses a la culture de mais]Contribution en azote de quatre legumineuses a la culture de mais

Examines ILCA's research on forage legumes in the past few years; discusses the potential role of forage legumes in increasing crop-livestock productivity in sub-Saharan Africa; and outlines priorities for future research.


Nnadi, L.A.Haque, I.[Les legumineuses fourrageres dans les systemes Africains d'agriculture mixte]Les legumineuses fourrageres dans les systemes Africains d'agriculture mixte

This paper looks at the applicability of three management oriented simulation models that are being evaluated by the environmental Sciences Division at ILCA. Basically the three models (CERES-maize NITROSIM and SCUAF) have been designed to simulate crop growth and development and crop yields, as ...


Saka, A.R.Haque, I.[Maize/Annual forage legumes mixed cropping systems: Characterizing water and Nitrogen dynamics in maize/vetch pure and mixed stands. II. Criteria for model selection and minimum data sets requirements for model use and verification]Maize/Annual forage legumes mixed cropping systems: Characterizing water and Nitrogen dynamics in maize/vetch pure and mixed stands. II. Criteria for model selection and minimum data sets requirements for model use and verification

Soil fertility is declining in most agro-ecosystems in sub-Saharan Africa, and incorporation of forage legumes into production systems to utilize the nitrogen fixed by the legumes could alleviate the problem, if efficient nitrogen-fixing legumes are used. The amounts of nitrogen fixed by Lablab, ...
