There are severe soil constraints for agriculture in many tropical regions of the world. Acidity and low levels of calcium are examples of them in the Brazilian Cerrados (Savannahs). They may prevent deep root growth of cultivated plants, exposing them to moisture stress during dry spells. This study aimed to develop a technique for screening soya beans varieties tolerant to low calcium based on root growth in nutrient solution. The results have shown varietal differences for tolerance to low-Ca stress. The method of screening for response to low-Ca is quick, non-destructive and can be employed in genetic studies and breeding programmes for efficient calcium utilisation by soya beans. It is expected that improved varieties for this character will lead to yield stability and contribute to develop sustainable farming systems in the savannahs. |
