Abstract

An experiment was carried out in pots, in the greenhouse, to evaluate the effects of phosphorus levels in soil solution (0.62, 3.25, 6.50, 9.75 and 19.50 uM P) and soil bulk density (1.05, 1.25 and 1.45 g. cm-3) on root growth and phosphorus uptake by tomato seedlings, cultivar ‘Campbell-27".
