Abstract

The objective of this research was to study the nutrient uptake of soybean exposed to aluminium (Al) toxicity. The factorial design consisted of two treatments arranged in a randomized block design with three replications. Liming was the first factor which consisted of four levels, i.e. i) without liming; ii) liming with 0.5×Al(exchangeable/ec); iii) liming with 1×Al(ec); and iv) liming with 1.5×Al(ec). Five genotypes were used as second factor, i.e. three tolerant genotypes (W3898- 14-3, Wilis, and Kawi), and two sensitve genotypes (MLG 3209 and MLG 3083). It was found that two tolerant genotypes, W3898-14-3 and Kawi, had a higher potassium (K) and sodium (Na) uptake than susceptible genotypes. Liming affected significantly the ratio of Al/[calcium (Ca) + magnesium (Mg)] in roots and leaves, the content of Ca and Mg in the roots and the content of Mg in the leaves. The K content in the roots and the content of Ca, K, and Na in the leaves were unresponsive to the alteration of pH and Al saturation.
