Abstract

                                The net assimilation rate of ADT. 27 rice at different growth stages was not influenced by phosphorus levels. The relative growth rate was more influenced by the lower levels of 30 and 45 kg P,O,/ha than the higher levels. The effect of P,Os levels was more on the shoot/root ratio at tillering stage, and dry matter production was associated with phosphorus supply at all the stages studied. P,Os at 45 kg/ha recorded the maximum 1000 grain weight.
