The initial response of plants to aluminium (Al) is an inhibition of root elongation. In the present study, short and medium-term effects of Al treatment (20??M) on root growth and Al accumulation of two common bean (Phaseolus vulgaris L.) genotypes, VAX-1 (Al-sensitive) and Quimbaya (Al-resistan...

Aluminum toxicity limits plant growth in acid soils. Because of their advanced state of weathering, acid soils of the tropics also tend to be deficient in nutrients. A realistic assessment of plant adaptation to these soils would therefore require Al-toxic conditions under which growth is simulta...

Phosphorus (P) deficiency and aluminium (Al) toxicity are widespread in Oxisols of the tropical savannas of eastern Colombia. A field experiment was conducted to determine the effect of Al toxicity and P deficiency on plant growth and nutrient uptake of two Brachiaria species. To examine the infl...

Alfalfa or lucerne (Medicago sativa L.) is an important forage legume grown extensively in the world. There have been relatively few investigations on the adaptation of alfalfa to soils found in suitable eco-zones in Africa. In the present investigations, twenty accessions were evaluated for tole...

Sesbania have multifarious utilization, and in many instances growth rate is one of the most important criteria for the selection of suitable Sesbania. This paper reports results of a study on the growth rates of Sesbania on two acid soils both low in available P, but one with toxic levels of Al....

Aluminium (Al) toxicity has a strong negative impact on crop productivity on acid mineral soils. Liming and fertilisation frequently are insufficient to overcome the problem, especially in tropical areas with subsoil acidity. The focus on breeding for acid soil tolerance as a more sustainable too...
