A field experiment was conducted at the Agricultural College Farm, Bapatla during kharif 2012 to study the effect of organic sources of nutrients (poultry manure, FYM, neemcake and vermicompost) and recommended NPK fertilisers on drymatter accumulation and nutrient uptake of rice. The results of the investigation showed that higher drymatter accumulation N, P and K uptake were recorded with 100 % RDN through chemical fertilisers which was significantly followed by 100% RDN through poultry manure. At 90 DAT and at maturity, significantly higher drymatter accumulation, yield and nutrient uptake were observed with fertiliser treated plots, which was on a par with 50% RDN as basal+ 50% at 10 days before PI stage through poultry manure and it is on a par with 100% RDN through poultry manure and significantly superior to all other treatments.
