The present study was conducted in aeroponic system to examine the effect of various P concentrations on different components of root system, shoot growth and P uptake of faba bean. The results indicated that increasing P concentration from 0.02 mM to 0.2 mM, there was a significant improvement in various growth parameters. Significant increase in leaf area and photosynthetic rate was observed only up to 0.2 mM P and further increase in P concentration did not increase these parameters. Response of lateral roots to P was greater than that of tap root. The increase in tap root surface area was less than two-fold whereas increase in lateral root surface area was eight-fold at 1 mM level of P concentration. Tap root maintained higher P content than lateral roots at all the P levels tested.
