Abstract

One per cent (w/v) solutions of monoammonium and diammonium phosphates either in the presence or absence of 1% urea were applied in the axyl of the "D" leaves of young plants grown in soil filled pots. There was no statistical difference between the two P sources. On the other hand, the presence of urea showed tendency to decrease internal transport of the applied phosphates irrespective of the source used.
