Aluminum is usually regarded as the determining factor for plant growth in acid soils and nutrient deficiencies are often additional growth-limiting factors in tropical acid soils. Taking into account the potential interactions between Al toxicity and nutrient deficiencies, the present study inve...

Thirty-four Stylosanthes scabra, 20 S. guianensis and 66 S. hamata accessions were compared for biomass production on an acid soil in a medium-altitude subhumid environment in southern Ethiopia. Accessions S. scabra (ILCA 12555, 11625, 11599 and 11608), S. guianensis (ILCA 11737 and 11776) and S....
Twenty-three accessions of Centrosema pubescens selected for good performance on an infertile, acid soil were tested along with 2 control lines each of C. pubescens and C. acutifolium at 18 locations in tropical America and one location in tropical China. The sites represent 3 major agroecosystem...
Common bean (Phaseolus vulgaris L.) proved to be very sensitive of low pH (4.3), with large genotypic differences in proton sensitivity. Therefore, proton toxicity did not allow the screening of common bean genotypes for aluminium (Al) resistance using the established protocol for maize (0.5 mM C...

Aluminum (Al) toxicity is a major limiting factor of crop production in acid soils, which are found mostly in developing countries of the tropics and sub-tropics. Common bean (Phaseolus vulgaris L.) is particularly sensitive to Al toxicity; and development of genotypes with better root growth in ...

Sesbania sesban and S. goetzei accessions were screened on Vertisols at PH 6.8 and acid clay soils (Nitosols) with and without application of phosphours (60 kg P/ha). Both species were generally well adapted to the Vertisols and grew to an overall mean height of 249 cm 14 months after transplanti...

Aluminium (Al) toxicity limits common bean productivity in acid soil regions of the tropics. To improve Al resistance of common bean, Al-sensitive Phaseolus vulgaris (SER16) was crossed to Al-resistant P. coccineus (G35346-3Q) to create 94 F5:6 recombinant inbred lines (RILs) of the pedigree SER1...
