Abstract:Different crops or varieties have different ability in uptake and utilisation of soil phosphorus (P). Using crop varieties with high phosphorus use efficiency (PUE) is one of important biological ways to alleviate shortage of P resources. Three spring faba-bean varieties (lines), LC5, 8354 and 8409, were sown in a high P deficiency alkaline soil to study the effect of P deficiency on grain yield. A pot experiment was conducted to study adaptable effects of P deficiency on root ecological and physiological ...
